Choose one of these topics: a superhero, a boring school day, stranded on a desert island. + + Now give the player a change to choose a happy or a bad end, just like in the example code. + Program both the endings. + + ### Exercise 2 + Copy the story you've created in your own story adventure in the previous levels. + Find a way to add at least 2 `{if}` and `{else}` commands to your story. + This can be with a happy or bad ending, but you can also try to find other ways to incoporate the commands. + example_code: | + ``` + name {is} {ask} 'Who is walking in the forest?' + {print} name ' walks through the forest' + {print} name ' encounters a monster' + end {is} {ask} 'Would you like a good or a bad ending?' + {if} end {is} good {print} name ' takes the sword and the monster quickly runs away' + {else} {print} 'The monster eats ' name + ``` + 7: + story_text: | + In a story, someone says words several times. For example, when someone calls for help or sings a song. + You can put such repetitions in your story, in this level with `{repeat}`. + + ### Exercise + Add repetition to your own story. Go back to your saved programs, choose your story program from a previous level and + find a line containing `{print}` and repeat it! + example_code: | + ``` + {print} 'The prince kept calling for help' + {repeat} 5 {times} {print} 'Help!' + {print} 'Why is nobody helping me?' + ``` + 8: + story_text: | + In this level you can use multiple lines in your `{if}` commands, this way you can upgrade your happy or sad ending! + + ### Exercise 1 + The example code shows two different endings; one where the characters jump in a time machine and one where they do not. + Complete the blanks with at least one sentence per ending. + **Extra** Make the story longer. What happens in the story? You can also add a second `{ask}` with different options. + + ### Exercise 2 + Go back to your saved programs, choose your story program from level 5. Now write a good and a bad ending of at least three lines long each! + example_code: | + ``` + {print} 'OH NO! The T-rex is closing in!' + end = {ask} 'Do you want a happy or a sad ending?' + {if} end {is} happy + {print} 'Just in time Richard jumps back into the time machine!' + {print} _ + {else} + {print} 'Oh no! Richard is too slow...' + {print} _ + ``` + 9: + story_text: "In this level you can use `{if}` and `{repeat}` commands inside other `{if}` and `{repeat}` commands. \nThis gives you many options and really helps you to make your story interactive.\n\n### Exercise 1\nFinish the code so the `{if}` works correctly.\n\n### Exercise 2\nAdd an `{if}` and `{else}` for the part of the story where Robin goes home too.\n\n### Exercise 3\nGo back to your level 8 story and use at least two `{if}`s inside another `{if}`.\n" + example_code: | + ``` + {print} 'Robin is walking downtown' + location = {ask} 'Is Robin going into a shop, or does she go home?' + {if} location {is} shop + {print} 'She enters the shop.' + {print} 'Robin sees an interesting looking book' + book = {ask} 'Does Robin buy the book?' + {if} book {is} yes + _ {print} 'Robin buys the book and goes home' + _ {else} + _ {print} 'Robin leaves the shop and goes home' + {else} + {print} 'Robin goes home' + ``` + 10: + story_text: | + In this level you can use the {for} command in your story.

Now make sure quotation marks are added in the right places. + example_code: | + ``` + name = 'The Queen of England' + {print} name ' was eating a piece of cake, when suddenly…' + ``` + 13: + story_text: | + By using the `{and}` and `{or}` commands, you can make your stories more versatile. You can ask two questions and respond to the combination of answers. + + ### Exercise 1 + Look at the example code and finish it. Then add at least 2 more `{if}` codes with `{and}` or `{or}`. + + ### Exercise 2 + Find a story from a previous level, and add one `{and}` or `{or}`. + example_code: | + ``` + {print} 'Our hero is walking through the forest' + {print} 'The path splits two ways' + path = {ask} 'Which path should she choose?' + weapon = {ask} 'What weapon does she draw?' + {if} path {is} 'left' {and} weapon {is} 'sword' + _ + ``` + 15: + story_text: | + Using the `{while}` loop can make your stories more interesting. For example, you can use `{while} game == 'on'` so you can play until the game is over. + Or you can use `{while} sword == 'lost'` so the player can't continue the game until they have found something. + + ### Exercise + The example code shows you how to use the `{while}` loop in a story. Now **think of your own scenario** in which the player has to find something before they can continue. + example_code: | + ``` + keys = 'lost' + {print} 'You are standing in your garden and you have lost your keys.' + {print} 'Where do you want to look for them?' + {print} 'You can choose: tree, flowerbed, rock, postbox' + {while} keys == 'lost' + location = {ask} 'Where do you want to look?' + {if} location == 'flowerbed' + {print} 'Here they are!' + keys = 'found' + {else} + {print} 'Nope they are not at the ' location + {print} 'Now you can enter the house!' + ``` + 18: + story_text: | + We are going to print another story, but now we have to use brackets with `{print}`. + + ### Exercise 1 + Create a story of at least 5 sentences. You don't have to use 'name' just yet. + example_code: | + ``` + {print}('Welcome to this story!') + ``` + story_text_2: | + ### Exercise 2 + We have already prepared an `{input}` for you. First, use the `name` variable in your story. + Then add a second `{ask}` and use that variable as well. + Tip: Remember the commas in a `{print}` between text and variables! + example_code_2: | + ``` + naam = {input}("What's your name?") + {print}('Welcome to this story!') + ``` + add_remove_command: + name: '{add} {to_list} & {remove} {from}' + default_save_name: add_remove_command + description: introducing {add} {to_list} and {remove} {from} + levels: + 3: + story_text: | + ## Add to + You can add items to the list with the `{add} {to_list}` command. To add an item to a list you can simply type: `{add} penguin {to_list} animals` or you can use the `{ask}` command like in the example code. + example_code: | + ``` + animals {is} dog, cat, kangaroo + like {is} {ask} What is your favorite animal? + {add} like {to_list} animals + {print} I choose animals {at} {random} + ``` + story_text_2: | + ## Remove from + If you can add items to a list, of course you can also take them off. This is done with the `{remove} {from}` command. + example_code_2: | + ``` + animals {is} dog, cat, kangaroo + dislike {is} {ask} What animal do you not like? + {remove} dislike {from} animals + {print} I choose animals {at} {random} + ``` + story_text_3: | + ### Exercise + Try out the new commands in this virtual restaurant.

If you want to check two statements, you don't have to use two `{if}`s but can use `{and}` and `{or}`. + + If you use `{and}`, both statements, left and right of the `{and}` need to be true. We can also use `{or}`. Then only one statement needs to be correct. + example_code: | + ``` + name = {ask} 'what is your name?' + age = {ask} 'what is your age?' + {if} name {is} 'Hedy' {and} age {is} 2 + {print} 'You are the real Hedy!' + ``` + ask_command: + name: '{ask}' + default_save_name: ask_command + description: Introduction {ask} command + levels: + 1: + story_text: | + ## The ask command + Now that you can use the `{print}` command, you are ready to learn the next command: `{ask}`. With the `{ask}` command, you can ask a question. Check it out: + example_code: | + ``` + {print} Hello! + {ask} What is your name? + ``` + story_text_2: | + ## The `{echo}` command + If you want the computer to repeat the answer back to you, you can use the `{echo}` command. The answer will be echoed back at the end of the sentence, so in this example after hello. + example_code_2: | + ``` + {print} Hello! + {ask} What is your name? + {echo} hello + ``` + story_text_3: | + ### Exercise + Try out the `{ask}` and `{echo}` commands. Firstly, fill in the blanks to make this program work. + Then ask 2 more questions using the `{ask}` command, after each `{ask}` use an `{echo}` to print the answer on the screen. + example_code_3: | + ``` + _ How are you doing? + _ + ``` + 2: + story_text: | + ## The ask command + Now that we can use **variables** in our codes, we no longer need the `{echo}` command. + We can use variables to store the answers to our questions and this way we can use the answer to multiple questions in our codes. + Check it out: + + This way your code is becoming interactive! + example_code: | + ``` + name {is} {ask} What is your name? + {print} Hello name + age {is} {ask} How old are you? + {print} name is age years old. + ``` + story_text_2: | + ### Exercise + In the previous tab you have practised with setting variables with the `{is}` command. + You have created at least 3 variables and used them with a print command. + Now, instead of setting the variables we want you to make the variables interactive, like we did in our example. + + Copy your code from the previous tab and make the variables interactive by using `{ask}` commands. + example_code_2: | + ``` + favorite_animal {is} {ask} What is your favorite animal? + {print} I like favorite_animal + ``` + 18: + story_text: The final change we will need to make to get Python code is changing `{ask}` into `{input}`. + example_code: | + ``` + {print}('My name is Hedy!') + name = {input}('What is your name?') + {print}('So your name is ', name) + ``` + blackjack: + name: Blackjack + default_save_name: Blackjack + description: Try to get as close to 21 as you can + levels: + 17: + story_text: | + Blackjack is a simple game of cards in which you have to get as close to 21 points as possible. You get two cards. Each card is worth their numeral value, and the face cards (Jack, Queen and King) are worth 10 points. + The Ace is worth either 1 or 11 points (you can choose). The dealer, your opponent, also gets two cards. + If you want, you can get another card, and its points will be added to your total. The dealer can also choose to take another card. + But be careful not to get more than 21 points, because if you do, you lose! + The player who gets closest to 21, without going over it, wins! + + ### Exercise + In this adventure we code the first part of our Blackjack game. We'll create a function to calculate how many points a card is worth. + + ***Set the variables*** + Start by making a list of all the cards, from 2 to Ace. Next make a list of the face cards, so Jack, Queen and King. Then pick a random card from the list of cards to be card_1. + + ***Create a function to calculate the points*** + Create a function that calculates how many points a card is worth. + All the face cards are worth 10 points, the Ace is worth 11 and all the other cards are worth their numeral. + Return the variable `points` at the end of the function. + + ***Test the function*** + Test if your function is working properly. Finish the first print command by filling in which card you've drawn. Then finish the second line by calling the function with card_1. + Run the code a couple of times. Are you happy with the results? Great! Then you can remove the testing part and move on the the next tab! + example_code: | + ``` + {print} 'BLACKJACK' + + # Set these variables + cards = _ + face_cards = _ + card_1 = + + # Create a function to calculate the points + {define} calculate_points {with} card: + {if} card {in} face_cards: + points = _ + {elif} _ + _ + {else}: + _ + _ points + + # Test your function + {print} 'Your card is a ' _ + {print} 'That is worth ' _ ' points'. + ``` + blackjack_2: + name: Blackjack 2 + default_save_name: Blackjack_2 + description: Blackjack part 2 + levels: + 17: + story_text: | + ### Exercise + In this adventure we code the second part of our Blackjack game. + + ***Paste your code from the previous adventure*** + In the previous adventure you've started a list of variables and created a function to calculate how many points a card is worth. Copy your code and paste it here. Mind that you don't need the testing part, so if you haven't removed that yet, please do so now. + + ***Add more variables*** + You have already set the lists `cards` and `face_cards` and the variable `card_1`. Underneath those variables create 3 more variables: `card_2`, dealer_card_1` and `dealer_card_2`. These variables are all set to a random card from the list of cards. + + ***Add up points*** + To calculate how many points you have scored we call the function with card 1 and we do it again for card 2. Then we add both these scores together to get your total. + Do the same thing for the dealers points, but be sure to use the dealer's cards and not your own! + + ***2 Aces*** + You're doing great! Almost all scores can be calculated now. There is only one exception: 2 Aces. If you get 2 Aces, your total is 12 points and not 22 (because 22 points would be losing!). This of course also goes for the dealer. + + ***Show the score*** + Lastly, you want to tell the program to tell you which cards you have drawn and how many points that is. Then show which cards the dealer has and how many points they have. + + ***Continue in the next tab*** + Great! You have finished this part of the game! Copy your code and go to the next tab to learn how to ask for an extra card and to declare a winner. + example_code: | + ``` + # Paste your code from the previous adventure here + + # Add these variables to the list of variables + card_2 = _ + dealer_card_1 = _ + dealer_card_2 = _ + + # Add up your points + your_points_1 = {call} _ {with} card_1 + your_points_2 = _ + your_total = _ + + # Add up the dealers points + dealer_points_1 = _ + _ + _ + + # 2 Aces + {if} card_1 == 'Ace' {and} _ + your_total = 12 + {if} dealer_card_1 _ + dealer_total = _ + + # Show the score + {print} 'You have drawn a ' _ ' and a ' _ '.

First ask the player if they want an extra card. + If they do, pick a random card and print what they have drawn. If the card is not an Ace, you can call the function and add the points to your total. + In case the card is an Ace, you can't use the function, because the Ace can be either 1 point or 11 points, depending on how many points you already have earned. + If your total is less than 11, you want the ace to be 11 points (because this is closest to 21). So you add 11 points to your total. + If the total is more than or equal to 11, you want the ace to be 1 point (because you don't want more than 21 points). So you add 1 point to your total. + Lastly, print your new total of points. + + ***Extra card for the dealer*** The dealer can also get an extra card. The dealer doesn't need to be asked, because they always get an extra card if their total is less than 17. + Copy the 'Extra card for you code' and paste it in the dealers section. Then change it to fit the dealer picking an extra card and getting points added to their total. + example_code: | + ``` + # Paste your code from the previous adventure here + + # Extra card for you + hit = {ask} _ + {if} hit == 'yes': + card_3 = _ + {print} _ + {if} card_3 _ 'Ace': + your_points_3 = _ + your_total = _ + {else}: + {if} your_total _ + _ + {else}: + _ + {print} _ + + # Extra card for the dealer + {if} dealer_total < 17 + _ + ``` + blackjack_4: + name: Blackjack 4 + default_save_name: Blackjack_4 + description: Blackjack part 4 + levels: + 17: + story_text: | + In the last 3 adventures you have alsmost created a working blackjack game!

Hopefully you've already made some awesome codes! + In the first level you might've notice that the `{echo}` command can only save one bit of information at a time. + For example in the restaurant adventure, you could echo what the costumer wanted to eat, or what they wanted to drink, but not both in one sentence. + + That changes in level 2. In level 2 you'll learn to work with variables, that allow you to save multiple pieces of information and print them in any place you want. + So let's go to the next tab! + example_code: | + **Warning! This code does not work!** + In Hedy commands will change sometimes. `{echo}` for example only works in level 1.

You can also use variables to make lists. + And you can even let Hedy pick a random word out of a list, which allows you to make real games! + Take a quick look at the next tab! + 4: + story_text: | + In the previous levels you've been practising with variables, but you may have come across this problem. + You might have tried to run a code like this: + + Of course you wanted to print + + `My name is Sophie` + + but Hedy prints + + `My Sophie is Sophie`. + + In this level this problem is fixed by using quotation marks. + example_code: | + ``` + name {is} Sophie + {print} My name is name + ``` + 5: + story_text: | + In the previous levels you've already learned to use `{at} {random}` which made your games different every time you ran the code. + But it's not really interactive, the player doesn't have any influence on what happens in the game. + + In this level you'll learn the `{if}` command, that allows you to give different responses in your program. This way you can program a secret password for your computer for example. + So let's go to next tab for the new command! + example_code: | + ``` + password {is} {ask} 'What is the correct password?' + ``` + 6: + story_text: | + In the previous level you have practiced with `{ask}` and `{if}`. For example you can ask guests what they would like to eat. + What you can't yet do though, is calculate the price for everyone's dinner. + + This level makes it possible to use addition, subtraction and multiplication in your programs. This way you can calculate the prices in your restaurant, but you could also add a secret code to give your friends and family a discount. + Another option in this level is programming your own maths game, for your little brother or sister to practice their multiplications. + Go see for yourself! + example_code: | + ``` + food_price {is} 0 + drink_price {is} 0 + total_price {is} 0 + {print} 'Welcome to McHedy' + order {is} {ask} 'What would you like to eat?' + {if} order {is} hamburger food_price {is} 5 + {if} order {is} fries food_price {is} 2 + drink {is} {ask} 'What would you like to drink?' + {if} drink {is} water drink_price {is} 0 + {else} drink_price {is} 3 + total_price {is} food_price + drink_price + {print} 'That will be ' total_price ' dollars, please' + ``` + 7: + story_text: | + Great job! You've reached the next level, which means you have practiced with `{if}` and `{else}`. You have probably noticed that your codes are getting longer and longer. + For example if you want to program 'Happy Birthday'. + + That's a lot of code for mainly the same words over and over again. Luckily in the next tab you'll learn a solution with the `{repeat}` command, that allows you to repeat a line of code multiple times. + example_code: | + ``` + {print} 'happy birthday to you' + {print} 'happy birthday to you' + {print} 'happy birthday dear Hedy' + {print} 'happy birthday to you' + ``` + 8: + story_text: | + Now you've learned how to repeat one single line of code.

It would look like this: + + If you'd also want the next verse 'stomp your feet', and the next one, and the next one, you'd have to change the code completely. + In this level you'll learn the `{for}` command, which allows you to make a list of actions and repeat the code with another action each time! + Please take a look! + example_code: | + ``` + {repeat} 2 {times} + {print} 'if youre happy and you know it clap your hands' + {print} 'if youre happy and you know it and you really want to show it' + {print} 'if youre happy and you know it clap your hands' + ``` + 11: + story_text: | + You have reached level 11, you're doing great! In the higher levels, Hedy is focussing more and more on teaching you the programming language Python. + In Python there is no `{repeat}` command, but there is a command that works like {repeat}.

Lucky for you, in this level you'll learn how to do this without this extremely long code! + example_code: | + ``` + first_grade = {ask} 'What score did you get on your first test?' + second_grade = {ask} 'What score did you get on your second test?' + added = first_grade + second_grade + mean_grade = added / 2 + {if} mean_grade = 1 {or} mean_grade = 2 {or} mean_grade = 3 {or} mean_grade = 4 {or} mean_grade = 5 + {print} 'Oh no!

You have passed the subject!' + ``` + 15: + story_text: | + In this game below a code has been made to make sure the player can play on as long as they want... + But the code is ineffective and way too long. Also, what if the player wants to play 101 games instead of 100? + You can't play to infinity? + In this level you will learn a command that makes all of this a lot easier! + example_code: | + ``` + game = 'on' + {for} i {in} {range} 1 {to} 100 + {if} game == 'on' + answer = {ask} 'Do you want to continue?' + {if} answer == 'no' + game = 'over' + {if} answer == 'yes' + {print} 'Ok we will continue' + ``` + 16: + story_text: | + In this level we will grow a bit more towards real Python code.

Head to the next tab to see which parts you need to correct. + 17: + story_text: | + Now we are going to change indentation a little bit. Every time that we need an indentation, we need `:` at the line before the indentation. + + In this level you can also use a new command: `{elif}`. `{elif}` is short for ``{else} {if}`` and you need it when you want to make 3 (or more!) options. + Check it out! + 18: + story_text: | + Congratulations! You have reached the last level of Hedy!

It should say "You have to throw again" if you've thrown anything else. + **Extra** Maybe you want to recreate a die from a completely different game. That's fine too! Then make up your own reaction, e.g. 'yes' for 6 and 'pity' for something else. + example_code: | + ``` + choices {is} 1, 2, 3, 4, 5, earthworm + throw {is} choices {at} {random} + {print} 'you have thrown ' throw + _ throw {is} earthworm {print} 'You can stop throwing.' + _ {print} 'You have to throw it again!' + ``` + 6: + story_text: | + You can also make an Earthworm die again in this, but now you can also calculate how many points have been rolled. + You may know that the worm counts 5 points for Earthworms. Now after a roll you can immediately calculate how many points you have thrown. + This is the code to calculate points for one die: + + ### Exercise + Can you make the code so that you get the total score for 8 dice? To do that, you have to copy and paste some lines of the code. + example_code: | + ``` + choices = 1, 2, 3, 4, 5, earthworm + points = 0 + throw = choices {at} {random} + {print} 'you threw ' throw + {if} throw {is} earthworm points = points + 5 {else} points = points + throw + {print} 'those are ' points ' points' + ``` + example_code_2: | + Did you manage to calculate the score for 8 dice? That required a lot of copy and pasting, right? We are going to make that easier in level 7! + 7: + story_text: | + You can also make a dice again in this level.

In earlier levels, we used `{for}` with a list, but we can also use `{for}` with numbers. + We do that by adding a variable name, followed by `{in}` `{range}`. We then write the number to start at, `{to}` and the number to end at. + + Try the example to see what happens! In this level again, you will need to use indentations in lines below the `{for}` statements. + example_code: | + ``` + {for} counter {in} {range} 1 {to} 10 + {print} counter + {print} 'Ready or not. Here I come!' + ``` + 17: + story_text: | + Now we are going to change indentation a little bit.

Or have you ever played with a magic eight ball? + Then you probably know that they can't really predict your future, but it's still fun to play! + + In the upcoming levels you can learn how to create your own fortune telling machine! + In level 1 you can start off easy by letting Hedy introduce herself as a fortune teller and let her `{echo}` the players' answers. + Like this: + example_code: | + ``` + _ Hello, I'm Hedy the fortune teller! + _ Who are you? + _ Let me take a look in my crystal ball + _ I see... I see... + _ Your name is + ``` + story_text_2: | + ### Exercise + Copy the example code into your input screen and fill in the blanks to make the code work. + **Extra** Change the code and let the fortune teller not only predict your name, but also your age, your favorite sports team or something else about yourself. + 3: + story_text: | + In the previous levels you've created your first fortune telling machine, but Hedy couldn't really predict anything, only `{echo}`. + In this level you can use a variable and the `{at} {random}` command to really let Hedy choose an answer for you. Check out this code for instance: + example_code: | + ``` + {print} I’m Hedy the fortune teller! + question {is} {ask} What do you want to know? + {print} This is what you want to know: question + answers {is} yes, no, maybe + {print} My crystal ball says... + {sleep} 2 + {print} answers {at} {random} + ``` + story_text_2: | + ### Exercise + Now, Hedy can only answer yes, no or maybe. Can you give Hedy more answer options, like 'definitely' or 'ask again'. + 4: + story_text: | + ### Exercise + We have removed all the quotation marks from this example code, can you add them in all the right places? + + ### Exercise 2 + Go back to the previous level and copy your fortune teller code. Make the code work in this level by adding quotation marks in the right spots. + example_code: | + ``` + _ Add the quotation marks to this code _ + {print} Im Hedy the fortune teller! + question {is} {ask} What do you want to know? + {print} This is your question: question + answers {is} yes, no, maybe + {print} My crystal ball says... + {sleep} 2 + {print} answers {at} {random} + ``` + 5: + story_text: | + ### Exercise + In the example code you see how to make a fortune teller program that allows you to tip the odds in your favor. This cheating program always tells you that you will win the lottery, but your friends will never win. + + Use this to make your own program, be creative! For example you could create a code that predicts that: + * your favorite sports team will beat all the competitors! + * your favorite movie will be chosen for movie night! + * you win tickets to your favorite show! + * you are the fairest of them all, like Snow White's magic mirror. + Let your imagination do the work! + + Your program has to exist of at least 10 lines of code and need to have at least one `{if}` and `{else}` command. + example_code: | + ``` + friends {is} Jordan, Lucy, Dave + {print} 'I can predict if you will win the lottery tomorrow!' + person {is} {ask} 'Who are you?' + good_answer {is} Hurray!

I see...' + {sleep} + {print} fortunes {at} {random} + ``` + functions: + name: functions + default_save_name: functions + description: functions + levels: + 12: + story_text: | + In this level you'll learn how to use **functions**. A function is a block of code you can easily use multiple times. Using functions helps us organize pieces of code that we can use again and again. + To create a function, use `{define}` and give the function a name. Then put all the lines you want in the function in a indented block under the `{define}` line. + Leave one empty line in your code to make it look nice and neat. Great job! You have created a function! + + Now, whenever we need that block of code, we just use {call} with the function's name to call it up! We don't have to type that block of code again. + + Check out this example code of a game of Twister. The function 'turn' contains a block of code that chooses which limb should go where. + + ### Exercise + Finish this code by setting the 2 variables chosen_limb and chosen_color. + Then, choose how many times you want to call the function to give the twister spinner a spin. + + ### Exercise 2 + Improve your code by adding a variable called 'people'. Use the variable to give all the players their own command in the game. + For example: 'Ahmed, right hand on green' or 'Jessica, left foot on yellow'. + example_code: | + ``` + sides = 'left', 'right' + limbs = 'hand', 'foot' + colors = 'red', 'blue', 'green', 'yellow' + + {define} turn + chosen_side = sides {at} {random} + chosen_limb = limbs _ + chosen_color = colors _ + {print} chosen_side ' ' chosen_limb ' on ' chosen_color + + {print} 'Lets play a game of Twister!' + {for} i {in} {range} 1 {to} _ + {call} turn + {sleep} 2 + ``` + 13: + story_text: | + Now that you've learned how to use functions, you'll learn how to use a function with an argument. + An **argument** is a variable that is used within a function. It is not used outside the function. + + For example in this code we've programmed the first verse of the song 'My Bonnie is over the ocean'. + In this example code the argument 'place' is used. Place is a variable that is only used in the function, so an argument. + To use 'place' we have placed `{with} place` after `{define} song`. + When the function is called, the computer will replace the argument 'place', with the piece of text after `{call} song {with}`. + + ### Exercise + The next verse of this song goes: + + ```not_hedy_code + Last night as I lay on my pillow + Last night as I lay on my bed + Last night as I lay on my pillow + I dreamed that my Bonnie is dead + ``` + + Can you program this verse in the same way as the example? + example_code: | + ``` + {define} song {with} place + {print} 'My Bonnie is over the ' place + + {call} song {with} 'ocean' + {call} song {with} 'sea' + {call} song {with} 'ocean' + ``` + 14: + story_text: | + In the previous levels you have learned to create functions and use arguments with them. Another great use of a function is to let it calculate something for you. + You can give the function a calculation and it will give you the answer of the calculation. This answer is called a **return value**. + + For example, in this code the function calculate_new_price will calculate the new price of any item. It will give you the new price as a return value. + + ### Exercise + Finish this code. We have already made the variable new_price for you, you only need to set it. + You should finish the line of code by calling the function that calculates the new price. + example_code: | + ``` + {define} calculate_new_price {with} amount, percentage + percentage = percentage / 100 + discount_amount = amount * percentage + {return} amount - discount_amount + + old_price = {ask} 'How much is on the price tag?' + discount = {ask} 'What percentage is the discount?' + + new_price = _ calculate_new_price {with} old_price, _ + {print} 'The new price is ' new_price ' dollar' + ``` + 18: + story_text: | + Let's make functions the Pythons way! To define a function, we no longer use: + + `{define} name_function {with} argument_1, argument_2:` + + but we use: + + `{def} name_function(argument_1, argument_2):`. + + + If you don't want to use arguments, you just leave the space between the parantheses empty. + To call a function, we don't need the `{call}` command anymore. You just type the name of the function. + example_code: | + ``` + {def} calculate_score(answer, correct_answer): + {if} answer == correct_answer: + score = 1 + {elif} answer == '?': + score = 0 + {else}: + score = -1 + {return} score + + answer = {input} ('Where can you find the Eiffel Tower?') + correct_answer = 'Paris' + score = calculate_score(answer, correct_answer) + {print} ('Your score is...

Now make an empty list for guessed_letters as well. + Then we fill in how many mistakes were made. At the start of the game, this should be 0. + The variable `amount_letters` tells us how many letters are in the answer. Ask Player 1 to tell us how many letters their word has. + Lastly we tell the computer if the game is over. We use the variable `game_over` and set it to `False`. + + ***Choosing the answer*** We want Player 1 to be able to choose the answer.

Fill in the while command accordingly. Now, Player 2 is allowed to guess a letter, so ask Player 2 to guess a letter. + We need to check if their answer is correct, so check if their `guess` is (somewhere) in the (list) `answer`. Then we let the computer figure out which of the letter(s) is the guess. We have already programmed that part for you. + Next we want to compliment the player for finding a correct letter and we want to print the list `guessed_letters`, so the player can see their progress. + + The next part we're going to program is what happens when the player has guessed all of the letters. So if their list of `guessed_letters` is the same as our list `answer`. + If the lists are the same, congratulate Player 2 with their victory and set the variable `game_over` to `True`. + + Next we'll program what happens when Player 2 guesses wrong (so the `{else}` command). First, tell the player that their guess was wrong. Then increase the `mistakes_made` variable by 1. + + For the last part we'll program what happens when Player 2 has made 10 mistakes.

An exercise allows you to practise the new commands and concepts, and lets you give your own twist to the example codes. + In this exercise you will see a pink blank space. You have to fill something in the place of the blank space before the code can be run. + + Fill in the `{print}` command in the blank space and then add five more lines of code. Each line has to start with a `{print}` command. + Have fun! + example_code_2: | + ``` + _ Hello! + ``` + 18: + story_text: |- + We arrived at real Python code!

Also the words you used to store something with `{is}`. + Most programming languages also use quotation marks when printing, so we are also getting a step closer to real programming! + example_code: | + ``` + {print} 'You need to use quotation marks from now on!' + answer {is} {ask} 'What do we need to use from now on?' + {print} 'We need to use ' answer + ``` + story_text_2: | + ## Contractions + Important! Mind that now that we're using quotation marks, Hedy will get confused when you use the apostrophe for contractions like I'm or What's. + Make sure to remove those apostrophes and change the spelling to I am or What is. + Check out the example code to see the wrong way of using apostrophes. + example_code_2: | + ``` + _ This is the wrong way of using apostrophes _ + {print} 'I'm babysitting my sister's kids' + {print} 'What's more fun than that?' + ``` + 12: + story_text: | + **All texts need to be in quotation marks** + For this level on you will also have to use quotation marks when storing a text with `=`: + example_code: | + ``` + name = 'Hedy the Robot' + {print} 'Hello ' name + ``` + story_text_2: | + **All items in lists need quotation marks too** + Lists are texts, so they need quotation marks too.

We also keep the quotation marks around each item like we have learned in previous levels. + We use square brackets to point out a place in a list. For example: `friends[1]` is the first name on the list of friends, as you can see in the first part of the example code. + The second part of the example code shows you that we can also match 2 lists using the variable i. + example_code: | + ``` + friends = ['Ahmed', 'Ben', 'Cayden'] + {print} friends[1] ' is the first friend on the list.' + {print} friends[2] ' is the second friend on the list.' + {print} friends[3] ' is the third friend on the list.' + #now we will match 2 lists using the variable i + lucky_numbers = [15, 18, 6] + {for} i {in} {range} 1 {to} 3 + {print} friends[i] 's lucky number is ' lucky_numbers[i] + ``` + story_text_2: |- + Now that you've learned to use the brackets in lists, you can also start using the {at} {random} command in the Python way! + You simply type the name of your list with `[random]` behind it! + example_code_2: |- + ``` + fruit = ['apple', 'banana', 'cherry'] + {print} fruit[random] + ``` + repeat_command: + name: '{repeat}' + default_save_name: repeat_command + description: '{repeat} command' + levels: + 7: + story_text: | + ## Repeat! Repeat! Repeat! + Level 7 adds the `{repeat}` command. `{repeat}` can be used to execute one line of code multiple times. Like this: + + ### Exercise + Play around with the `{repeat}` command. Can you make the happy birthday song in only 3 lines of code instead of 4 now? + example_code: | + ``` + {repeat} 3 {times} {print} 'Hedy is fun!' + ``` + 8: + story_text: | + ### Repeat commands and indentation + In this level you can repeat multiple lines of code with only 1 repeat command. + You do this by making a block of lines that you want to repeat. + The lines in this block will need **indentation** . + That means putting four spaces at the beginning of each line. You will also have to indent when you just want to create a block of one line. + example_code: | + ``` + {repeat} 5 {times} + {print} 'Hello everyone' + {print} 'This is all repeated 5 times' + ``` + 9: + story_text: | + Great job! You've reached another new level! In the previous level you've learned to use multiple lines of code in an `{if}` or `{repeat}` command. + But you can't yet combine the two... + + Good news! In this level you will be allowed to put an `{if}` inside an `{if}`, `{repeat}` inside a `{repeat}` command and in eachother. + Give it a try! + example_code: | + ``` + {repeat} 3 {times} + order = {ask} 'What would you like to order?' + {if} order {is} pizza + {print} 'Yammie' + {else} + {print} 'pizza is better!' + ``` + repeat_command_2: + name: '{repeat} 2' + default_save_name: repeat_command_2 + description: '{repeat} command 2' + levels: + 7: + story_text: | + ## Repeat with other commands and with variables + You have practiced the `{repeat}` command in combination with the `{print}` command now, but did you know you could also use other commands with `{repeat}` ? + In this example code you can see that `{repeat}` can also be used with an `{ask}`, `{if}` or `{else}` command. + example_code: | + ``` + {repeat} 2 {times} answer = {ask} 'Did you know you could ask a question multiple times?' + {if} answer {is} yes {repeat} 2 {times} {print} 'You knew that already!' + {else} {repeat} 3 {times} {print} 'You have learned something new!' + ``` + story_text_2: | + Another interesting thing you can do with the `{repeat}` command is using variables to set the amount of times something should be repeated. In the example code you can see that we first ask the person how old they are. + Then, in line 3, the question is repeated 'age' times. So we have used the variable 'age' with the `{repeat}` command. + example_code_2: | + ``` + {print} 'Yay! It is your birthday!' + age = {ask} 'How old are you now?' + {repeat} age {times} {print} 'Hip Hip Hurray!' + ``` + 8: + story_text: | + ### In the block or not? + In this level you have to think carefully which lines of code should be in the block and which shouldn't. + For example: If you want to sing the song *the muffin man*. You only want the line with 'the muffin man' to be repeated twice. + This means the last line shouldn't start with indentation as it doesn't belong to the block. + If you do start the last line with indentation the song will turn out wrong. + + ### Exercise + Each line in the example code starts with a blank. Remove the blanks and try to figure out which line need indentation and which don't to make the muffin man song. + example_code: | + ``` + _ {print} 'Do you know the muffin man?' + _ {repeat} 2 {times} + _ {print} 'The muffin man' + _ {print} 'Do you know the muffin man, who lives on Drury Lane?' + ``` + restaurant: + name: Restaurant + default_save_name: Restaurant + description: Create your own virtual restaurant + levels: + 1: + story_text: | + In level 1 you can make your own virtual restaurant and take your guests' orders. + story_text_2: | + ### Exercise + Copy the example code into your input screen by clicking the yellow button. + Firstly, fill in the correct command on the blanks to make to code work properly. + Then add at least 4 more lines of code to the restaurant program. + Ask the costumer what they would like to drink and ask if they want to pay with cash or card. + Lastly, think of a nice way to say goodbye to your costumer. + example_code_2: | + ``` + {print} Welcome to Hedy's restaurant 🍟 + _ What would you like to order? + {echo} So you would like to order + {print} Thank you for your order! + {print} It's on its way! + ``` + 2: + story_text: | + In level 2 you could expand your restaurant by using variables. In level 1 Hedy could only `{echo}` the order once and only remember the last thing that was ordered. + Now you can use variables and Hedy can remember both the food and the toppings! + example_code: | + ``` + {print} Welcome to Hedy's restaurant! + {print} Today we're serving pizza or lasagna. + food {is} {ask} What would you like to eat? + {print} Great choice! The food is my favorite! + topping {is} {ask} Would you like meat or veggies on that? + {print} food with topping is on its way! + ``` + story_text_2: | + ### Exercise + Copy your own restaurant code from to previous level to the input screen below. + Fix the code by replacing the `{ask}` and `{echo}` commands and using variables, like you've learned in this level. + + Now that your code is working again, it's time to add something more. + Look at the last line of the example code: `{print} food with topping is on its way!` + In this single line 2 variables have been used to create a summary of the order. + Now add your own summary of the food and drinks ordered by the customer. + + **Extra** Now that you've learned how to use variables, you can use as many variables in one line as you'd like. Can you add more variables to your code, like eat in or take-away, cash or card, with or without a straw etc.? + 3: + story_text: | + Having trouble to decide what you wanna have for dinner? You can let Hedy choose for you! + Simply add lists of your favorite (or least favorite) meals and Hedy can randomly choose your dinner. + You can also have a bit of fun, by letting Hedy choose the price for your dinner as well! What will you get? + example_code: | + ``` + dishes {is} spaghetti, brussels sprouts, hamburgers + {print} You will have dishes {at} {random} tonight! + prices {is} 1 euro, 10 euros, 100 euros + {print} That will be prices {at} {random} please. + ``` + story_text_2: | + ### Exercise + Now make your own version of the random restaurant. + Make a list of starts, mains, desserts, drinks and prices yourself. + Then use `{print}` and `{at} {random}` commands to tell the costumer what will be on their menu tonight. + example_code_2: | + ``` + {print} Welcome to your own random restaurant! + starters {is} _ + mains {is} _ + desserts {is} _ + drinks {is} _ + prices {is} _ + _ + ``` + 4: + story_text: | + In the restaurant you have to use quotation marks too when using the `{print}` or `{ask}` command. + + ### Exercise + Add the quotation marks to this code to make it work! Be careful: variables should not be in quotation marks. + Then, use the `{clear}` command to only show one line at a time in your output screen. + + ### Exercise 2 + Go back to the previous level and copy your restaurant code. Make the code work in this level by adding quotation marks in the right spots and add some `{clear}` commands. + example_code: | + ``` + _ Add the quotation marks to this code _ + {print} Welcome to Restaurant Chez Hedy! + {print} Today we are serving pizza or lasagna. + food {is} {ask} What would you like to eat? + {print} Great choice! The food is my favorite! + topping {is} {ask} Would you like meat or veggies on that? + {print} food with topping is on its way! + drinks {is} {ask} What would you like to drink with that? + {print} Thank you for your order. + {print} Your food and drinks will be right there! + ``` + 5: + story_text: | + ### Exercise + The example code shows how you could program that you've run out of a menu item in your restaurant. + Copy your own restaurant code from the previous levels.

This list is filled with 9 dots, since there are no x's and o's yet at the start of our game. + + ***Create a function that prints the field*** Firstly, clear the screen so the old playing fields will be removed. Then we print the first line of our Tic Tac Toe field. This line constists of the first 3 spots in our list field. + We have already programmed this line for you. Now finish the field by printing spot 4, 5, and 6 on the second row and spot 7, 8 and 9 in the third row. + + ***Call the function that prints the field*** Now call the function. +

This means you have to make this for the other 2 rows, 3 columns and 2 diagonals. + If you've finished all the other options, the function should return the variable `game_over` so we can use it in our game. + + ***Call the function in the game*** Go to the line `game_over = {ask} 'Did you win?'` and change it to `game_over = {call} detect_winner {with} field, sign`.

Now you'll learn how to create the game! + + ### Exercise + ***Paste your code*** Start by pasting your code from the previous adventure here. + + ***Add variables*** Underneath your list called `field` we'll add 2 more variables that we'll need to program the game. + The variable `game_over` tells us if the game is over, and should be 'no' at the start of the game. + The variable `sign` tells us if it's the turn of player x or player o. Set the variable to 'x'. + + ***The game*** First use a {while} command, to make sure the game keeps on playing the variable while game_over is set to no. + During the game, we first ask the player which spot they choose. Then we change the field with the number they chose into their sign. + Then we print the field again and we ask the player if they've won yet. Lastly we want to switch whose turn it is, so if the sign is 'x' it should be 'o' and the other way around. + + ***Test your game*** Does your game work? Great, have fun playing the game!

The short explanation at the beginning of each level and the short example programs help to give the children a quick insight into what is new in the chosen level. The different assignments that the children can choose also work very well. You see the children choose assignments that appeal to them and they then get to work with them, through the levels.

The adventures can be done by the students individually, or you can use them in a classical instruction. + + The adventures also include a code example, to make sure the less digitally informed teachers are able to use Hedy too! + Of course Hedy also caters to the creative teachers that love to make their own lessonplans and adventures! + + After programming all the adventures of a certain level, your students can test their knowledge in the quiz. + You can track your students' work and their progress on the class page. + - title: Devices + text: |- + Hedy is web-based, which means it works on any device with a browser (Google Chrome, Firefox, Edge etc), so laptops, Chromebooks, tablets and even smartphones are suitable to use Hedy. + There's no need to download anything before working with Hedy, just go to the website and you're all set! + - title: The Hedy Community + text: |- + All Hedy teachers, programmers and other fans are welcome to join our Discord server. This is the ideal place to chat about Hedy: we have channels where you can show your cool projects and lessons, channels to report bugs, and channels to chat with other teachers and with the Hedy team. + Here you can find a video on how to join the Discord Community. + - title: Hedy and the GDPR + text: |- + Organizations in the EU have to comply with the GDPR (General Data Protection Regulation) when processing personal data. + Because this is a complex issue for many schools, you can use all Hedy programming functionalities without sharing personal data. + The easiest way to do this is to use Hedy without creating accounts for the teacher and students. Without accounts, all functionality is available, with the exception of personalizing levels, saving students' programs and viewing their progress. That is limiting, but there are schools that use Hedy in that way. + + A second way is for a teacher to create an account with an email address without personal data, for example "docent25@email.com". Apart from an email address, which is only required to reset your password, you do not need to share any information when you create a teacher account. + With a teacher account, you can create anonymous accounts for students, e.g. rainbow-student1, rainbow-student2, etc (See 'Teaching preparations' for a detailed manual). This way you can use all functionality of Hedy, including saving progress, without sharing personal data of yourself or your students. + + If the above is not sufficient for your context, we can sign a processing agreement for the processing of your personal data. +- title: Tutorial + key: tutorial + subsections: + - title: Tutorial + text: Do you want to follow the tutorial (again)? Click here. +- title: Teaching preparations + key: preparations + subsections: + - title: For teachers + text: You can prepare your classes at the For Teachers page. On this page you'll find everything you'll need to teach with Hedy, like your classes, your adventures and slides. All the functionalities of the for teachers page are explained below. + - title: Creating a Class + text: |- + As a teacher, you can create a class for your students. In this class you can see the students' accounts and their programs and you could monitor their progress. + This video shows you how to quickly create a class in Hedy. + - title: Duplicate a class + text: |- + Are you teaching multiple classes? Then you don't have to customize each class individually. Simply make a class, costumize the class (see "Customize your Class" to learn how) and then duplicate this class as many times as you want. + You can duplicate the class on the 'For Teachers' page. If you duplicate a class, all the class settings are duplicated as well. This means that all the levels and adventures you've mande unavailable for the first class will now be unavailable for the new class(es) as well. + The student accounts and second teacher accounts in your class will not be duplicated into the new class. + - title: Add a second teacher + text: |- + Are you not the only teacher that teaches your class? Then you can now add another teacher to the class. Go to the 'For teachers' page and click on the class. Then choose 'Invite a teacher' and fill in the username of your colleague. + Your colleague will get an invitation on their account to join your class. They can see that invitation message by clicking on their username in the upper right corner of the screen and selecting 'My account'. + Once the other teacher accepts the invitation they can customize the class as well. + To remove a second teacher from your class, go to the class page and remove the second teacher. The teacher who's created the class cannot be removed. + - title: Customize your Class + text: |- + You can customize your class and choose which adventures are available for your students. This way your students won't be overwhelmed by the amount of adventures and levels, and they can specifically focus on the adventures you'd like them to practice with. + Click on your class on the for teachers page and choose 'customize class'. On this page you can select levels, set opening dates, unlock level thresholds and more. + + **Select and order adventures** + + In this section you can select and order adventures. The pink tabs are adventures with new commands. The gray tabs are regular adventures. To rearrange the order of the adventures, you can drag the tabs. However, we do advise you to use the regular order of adventures as the Hedy team made sure the adventures go from easiest to hardest. + If you want to remove an adventure for your students, simply click the cross on the adventure's tab. + + If you want to add adventures, for instance your own adventure or an adventure you accidentally removed, use this menu to add the adventure to your students' adventures. Simply click the adventure you want to add and it (re)appears in the line of adventures. To undo all your changes to the adventures, click 'Reset'. + + **Opening dates** + + With this feature you can set opening dates for the levels. This way you can make a lesson plan before your course begins and not worry about opening new levels each week. In the image above the first level is opened directly, the second will open the 23th of september, and the 3rd level the week after. The other levels are closed. + Don't want to set opening dates? No problem, just leave this section blank. + + **Unlock level thresholds** + + This featue allows you to set a threshold for your students' quiz grade, before they can continue to the next level. For example, if you enter "80" your students have to score at least 80% on the quiz before they are allowed to go to the next level. If they haven't met the threshold, they are not allowed to continue and have to retake the quiz. + Don't want to use the threshold? No worries, just keep this section blank. + + + **Other settings** + + There are some other setting that could be usefu to you aswell. Our first extra setting is 'Mandatory developer's mode'. In developers mode the students only see their input and output screens and the run button. The adventures are hidden and there are no cheatsheets available. This might come in handy in a test situation. + If this option is not selected the developer's mode is available for students too as a voluntary option. + + If you want all your students to be visible in de class highscore, you can select the second option. + With all the other options you can choose to hide some functions or content for your students, this might help them focus more. + + **Save** + + Don't forget to save your changes when you're done customizing your class. + - title: Student Accounts + text: |- + To add students to your class go to the class page by clicking in the class name on the 'for teachers' page. Then click 'add students'. There are 2 ways to let your students join your class: You can create accounts for them, or they could create their own accounts. + + **You create accounts for your students** + The easiest way to add students to your class is by creating an account for them. This can be done by clicking the 'create student accounts' button and filling in the usernames and passwords for them. + The students can login with the username and password that you chose. Afterwards, they can change their username or password if they'd like and they'll still remain in your class. + This video shows how to add students to your class in the quickest and easiest way. + + **Students make their own accounts** + Your students can also go to the Hedy website and create their own accounts, just like you did. To get them into your class, they simply have to click the invite link. + You can find the invite link on the class page and send it to your students. Mind that your students have to be logged in to Hedy when they click the link, in order to make it work smoothly. + You can also manually invite a student to your class with the button 'Invite by username'. + - title: Setting preferred language + text: |- + When students create profiles they are supposed to choose a 'preferred language'. Hedy will always be loaded in this selected language. + Changing this language can always be done later on by navigating to 'My account' and 'My personal settings' again. + + **For non-English speakers** + Not only can you change the language of the adventures to your own language. You can also choose which language the keywords (for example 'print' or 'ask') should be in. + This way you can teach your students to code with English keywords, but you can also let them program in their own language. For example, Dutch students can use the command 'vraag' instead of 'ask'. + If a student wants to switch languages, they can click the keyword switcher. It will switch the keywords from English to the preferred language and back. + Fun fact! Students are allowed program in both English and their own language at the same time! So, if they have trouble remembering some keywords in English, but easily remember other ones they can use both at the same time. + + + **Video** + This video show you how to set a preferred language and change the keywords to you preferred language as well. + - title: Storing programs + text: |- + When you are logged in, you'll see My programs next to your profile icon. + This option exists for your students too. In My programs you can find all the programs that you've worked on. + By default, programs will be saved to 'My programs' when you run the code, and every 10 seconds, under their default name + and their level (for example: Story 5). If you want to store a program under a new name, just type the new name in the name bar. + Currently, only one program can be saved per level, per tab. + + You (and your students) can also share programs using the share button next to program names. + These programs will be posted on our explore page, for everybody to see and use. + If you want to unshare your program, go to 'My programs' and click 'Unshare'. + + The paper plane icon can be used to hand in programs to the teacher of a class. Programs that have been handed is will no longer be editable. +- title: Teaching with Hedy + key: teaching + subsections: + - title: Teaching with Hedy + text: |- + Hedy contains a lot of different levels that each teach a different new skill. We recommend to teach one level per lesson. + This gives your students the time to fully grasp a new command or concept and practice with it, before moving on to the next level. + We use this structure in our lessons: Introduction, New concepts and commands, let's get to work, puzzles and quizzes. + - title: Slides + text: |- + When giving instructions you might want to use our slides. Our slides are available on the 'For teachers' page. There is a set of slides for each level. In the slides all the new commands for that level are explained. We have aimed to explain why these changes are nessecary or how the new commands come in handy. + We also give some examples of how the new commands can be used. You could of course also use your own slides, or just open Hedy and show your students around the website. Whichever you prefer to give the best Hedy lessons! + - title: Introduction + text: |- + You can start your lessons by activating your students' prior knowledge: What do they already know about the subject, what did they learn in the previous lesson and which mistakes did they make that they've now learned from? + This way all the previously learned commands and frequently made mistakes are fresh in your students' memories, when you start introducing the new lesson. + - title: Introduction of new concepts and commands + text: |- + The new concepts and commands can be very hard for some students to fully understand. + That's why it's of importance to model the proper use of the new commands to your students. + Especially in the lower levels, where some students have no experience with programming at all, it can be hard for them to understand the new abstract concepts. + Showing a lot of examples makes an abstract concept (for instance: 'What is a variable?') more recognizable and easier to understand ('Look, the variable pet changed into dog'). Our slides could help you with that. + - title: Let's get to work + text: |- + Each level contains different adventures that you can find in the pink tabs. The first pink tab explains the new commands in this level. + The following tabs are adventures that the students can try out and make their own. + The adventures are arranged from easiest to hardest, so we recommend to start on the left and your your way to the right. + The last tab 'what's next' gives a little teaser of what you'll learn in the next level. Of course, you can select the adventures you want your students to do for each level. + They don't always have to make every adventure. Every adventure contains an example code, that the students can try out with the green button. + The example code gets copied to the workfield, where the students can try out the code and adjust it to make it their own. + Stimulate your students to turn the example code into their own projects by adding their own ideas and making their own variation of the adventure. + - title: Quizzes and puzzles + text: |- + To test whether your students have picked up all the new info in the level, you can let them take the quiz. + The quiz contains 10 multiple choice questions about the new concepts and command to that level. + Not every level has a quiz yet, as we are still building the quizzes. + Some levels also contain puzzles. Puzzles show the students a couple of line of code that the students have to put in the right order. + + This video shows the quizzes and puzzles. + - title: Evaluation + text: |- + Round up your lesson by having a brief evaluation. What did the students learn? Which hardships did they come across? + How did they learn from their mistakes? And of course: What did they create? + Students are often very proud of their own creations, so it's nice to save a little time and give your students the opportunity to show their work to their classmates. +- title: Teacher Statistics + key: teacher_statistics + subsections: + - title: Live Dashboard + text: |- + If you would like to keep track of your students' progress, you can make use of the live dashboard. You can find the live dashboard by clicking 'Live statistics' on your class page. + + All the features of this dashboard are explained below. + - title: Level Selection + text: |- + + Firstly, you can select the levels you'd like to see on the dahsboard. Select the levels your students are currently working on by clicking on the number of that level. Deselect levels that you do not want to see by clicking them again. + In this example level 1 and 2 are selected. You can click on refresh to refresh the dashboard and get the most current stats. + - title: Class Overview + text: |- + + In the class overview you can see which adventure your students are working on right now. You can see that one student is working on the 'Rock, Paper, Scissors' adventure in level 1, one is working on the 'Fortune Teller' in level 1 and one student is working on the 'Rock, Paper, Scissors' adventure in level 2. + If you'd like to know which of your students is working on the adventure, simply click the number and their accountnames will appear. + You can also see how many of your students have finished the quiz. In this case, one student finished the quiz in level 1. Again, you can click the 1 to see which of your students it is. + + You can also see one of the students is 'missing' from this overview. That's because he's working on an adventure in level 4, which is not selected. + - title: Student List + text: |- + + Here you can find a list of your students and you can see their individual progress. The blue ring shows you what your students are currently working on. + + It is important to notice that the blue dots means that a students 'attempted' the adventure. This means that they ran a code in this adventure and went on to the next adventure, so this does not automatically mean that they did a good job! + If you want to see how an individual student is getting along, you can click their name in this overview. This is what you see if you click on marleen_h3a for example: + + You see that Marleen is having some trouble programming. She tried to run a program that contains blanks multiple times, so she might not realize that she has to change the code examples before running them. + In this way this overview can give you a better understanding of what a student is struggling with. + - title: Common Errors + text: |- + + If you're not only interested in individual struggles of your students, but you'd like to know what the whole class seems to be doing wrong, you can use this oversight of common errors. + The most common error messages that your students are recieving will appear in this oversight for you, so you could give some more instructions to the whole class if needed. + By clicking the error, you can see which students are having trouble with this error. By clicking resolve, you'll remove this error from the list. + - title: Overview of programs per adventure + text: |- + + Another useful overview of all the programs your students made in a level can be found on your class page. Go to the class page and click 'Overview of programs per adventure'. Here you'll find this overview. + You could use this overview to check your students' work. If they have made a program in an adventure, an eye appears in your overview. Click the eye to view their work. Did you like it? Then you can check the box and a green tick will appear. + This way you create a nice overview for yourself of your students' results. +- title: Extra Hedy features + key: features + subsections: + - title: Make your own adventure + text: It is also possible for teachers to create your own adventure. This video shows you how to create your own adventure as a teacher and add it to your class(es). + - title: Explore page + text: |- + On the explore page you can view the work of other Hedy users. You can try out their programs and use them as inspiration to create something cool yourself. + You can also add a program you've made to the explore page yourself by clicking 'Save and share code' in the coding screen or go to My Programs and click 'Share'. + Don't want to share your work anymore? Simply go to 'My Programs' and click 'Unshare'. + If you want more information about the explore page, check out this video. + - title: My achievements + text: |- + If you click on your username in the topright corner of your screen, you can go to My achievements.

There are hidden badges too, of which you'll have to find out yourself how to earn them. + If you want more information on the achievements, check out this video. + - title: High Scores + text: |- + On this page you can see the high scores of all Hedy users. + In this videoyou can learn some more about the high scores. + - title: Debugger + text: |- + Is your (student's) code not working? There must be a bug (coding mistake) in it! You can use the debugger to find the mistake. + The debugger is the ladybug button in your coding screen. If you press it, you can run your code line by line to find your mistake. + Have you found the mistake? Press the red stop button and the debugger will shut off. + - title: Read aloud + text: Do you want the output of your program to be read aloud? Then you can use the read aloud function that is found under the 'run code' button in your coding screen. + - title: Programmers mode + text: |- + Distracted by all the adventures, or do you want to make a long program? Then check out the 'Programmers Mode' switch at the bottom of your coding screen. + Programmers mode allows you and your students to use a bigger coding screen. + - title: Cheat sheets + text: |- + In every level there is a button with this emoji 🤔. You and your students can find the "cheat sheets" there. On this cheat sheet, you can find all the commands that are usable in this level in their correct form. + So if you've forgotten how a command works, simply take a peek at the cheat sheet! + - title: Video + text: This video shows you even more features of Hedy, like the cheatsheets and the keyword switcher. +- title: After Hedy + key: after + subsections: + - title: What to do after Hedy? + text: |- + Congratulations on reaching the end of Hedy! Your students have now learned how to create their own basic programs in the Python programming language. + Of course, you could keep programming in our Hedy compiler, but it might be more exciting for your students to transfer to a "real" Python interface. + Would you like to continue teaching Python? Then please visit the Python website to learn how to get started in another compiler. + + Now that your students have a basic knowledge of programming in general, you could also show them around in other textual programming languages. The language might change but the concepts do not, so Hedy will still give them a big advantage. +- title: Answers to the exercises + key: answers + intro: |- + The answers to all the exercises can be found on the public profile of the useraccount 'Hedy_answers'. We often encourage students to use their own creativity in their answers, so these answers are merely a guideline as to what a possible correct answer could look like. + + To go to the 'Hedy_answers' profile, please click here. +- title: Common mistakes + key: common_mistakes + intro: |- + You can learn from your mistakes, especially in coding! Making mistakes is unavoidable, and a great opportunity to learn, but for teachers, it can be a challenge to find the correct fix for a mistake! Especially as the programs get longer and longer as the students progress through the levels. That's why we've made a list with frequently made mistakes in each level, and their solutions. + levels: + - level: '1' + sections: + - title: Students forget to type commands + example: + error_text: For example they type a sentence without using print. + error_code: Hedy can't print this + solution_text: Teach your students to always start a line of code with a command. + solution_code: '{print} Hedy can print this!' + - title: Students use capitals when typing commands + example: + error_text: Commands won't work if they are in capitals. + error_code: |- + Ask Why does my code fail? + Print Because I'm using capitals. + solution_text: Remove the capitals. + solution_code: |- + {ask} Why does my code work now? + {print} Because I removed the capitals! + - title: Students use echo without ask + example: + error_text: Echo is made to repeat an answer after an ask command. Without ask echo won't do anything. + error_code: '{echo} Your name is' + solution_text: Add an ask command to make it work. + solution_code: |- + {ask} What's your name? + {echo} Your name is + - title: Students want their echo word (variable) to be in the middle of a sentence + example: + error_text: And they are right! That's why they will learn to use proper variables in the next level. + error_code: |- + {ask} Which programming language is the most fun? + {echo} is the best! + solution_text: 'In level 1 we have to keep it at this:' + solution_code: |- + {ask} Which programming language is the most fun? + {echo} The best is... + - title: 'Turtle: Students let the turtle walk off of the screen' + example: + error_text: Often students love to try out big numbers when using the turtle, which causes the arrow to walk off the screen. + error_code: |- + {forward} 300 + {turn} 90 + solution_text: In the example, students tend to think that the turn command failed; even though it did what it what supossed to. What happened is the turtle walked past the screen limits. Use smaller numbers to prevent this from happening. + solution_code: |- + {forward} 100 + {turn} 90 + - title: "Turtle: Students use the command backward, but there's no such command." + example: + error_text: Backward is not a command. + error_code: backward 100 + solution_text: 'To make the turtle go backwards, you use the forward command and a negative number. For example:' + solution_code: '{forward} -100' + - level: '2' + sections: + - title: Students make typos in their commands + example: + error_text: Hedy can't recognize a command with a typo. + error_code: prinnt Don't make typos + solution_text: Teach your students to read the error messages. This way they can find out themselves what went wrong. + solution_code: "{print} Don't make typos" + - title: Students forget that the ask command has changed + example: + error_text: In this level students learn about variables. The ask command requires a variable as well, but students forget this. + error_code: ask what would you like to eat + solution_text: In this level you have to tell Hedy where to save your answer, so it can be used later on. This is called a variable. + solution_code: order {is} {ask} What would you like to eat + - title: Students try to use the `{echo}` command + example: + error_text: For some students it might be frustrating to learn that the `{echo}` command doesn't work anymore. That's why it's very important to explain the advantages of using variables. For example you can use multiple variables in a code, and you can put them anywhere you like in a sentence! + error_code: |- + answer {is} {ask} Why doesn't {echo} work anymore?! + {echo} + solution_text: Use a variable instead. + solution_code: |- + answer {is} {ask} Why doens't {echo} work anymore?! + {print} answer + - title: Students use a variable name or as a normal word + example: + error_text: In the example below the word 'name' is used as a variable, but also as a normal text. The output of this code will be 'Hi my Hedy is Hedy'. + error_code: |- + name {is} Hedy + {print} Hi my name is name + solution_text: So don't use a word you want to use in the text as a variable name. In level 4 this is solved with quotation marks. + solution_code: |- + name {is} Hedy + {print} Hi I'm name + - title: Students use long variable names containing two words. + example: + error_text: A variable should be named with one word. You could use an underscore to connect two words. That counts as one. + error_code: chosen door is ask Which door do you pick + solution_text: Add an underscore. + solution_code: chosen_door {is} {ask} which door do you pick + - title: Students might use two different names for the same variable + example: + error_text: In this example the student has used 'horse' and 'name' for the same variables. + error_code: |- + horse {is} {ask} What is your horse called + {print} Your horse is called name + solution_text: Always check whether the variable has the same name throughout the code. Slight differences can be hard to spot (for example plurals) but they will interfere with the code. + solution_code: |- + name {is} {ask} What is your horse called + {print} Your horse is called name + - level: '3' + sections: + - title: Students try to print whole lists + example: + error_text: A list can't be printed. You can only print one item from the list with {at} {random}. + error_code: |- + groceries {is} apples, milk, chocolate + {print} groceries + solution_text: To print a list of all the groceries, you simply need to put them after a `{print}` command. Else you can use the list to print one item with `{at}` `{random}`. + solution_code: |- + {print} apples, milk, chocolate + + # or + + groceries {is} apples, milk, chocolate + {print} groceries {at} {random} + - title: Students use the name of a variable or list as regular text + example: + error_text: This problem probably occured in level 2 as well. Now it can happen with lists too. + error_code: |- + name {is} Hedy + {print} Hi my name is name + + # or + + animal {is} rhino, bee, swan + {print} The best animal is... animal {at} {random} + solution_text: Don't use the names of variables or lists in regular text to print. In level 4 this problem is solved with quotation marks. + solution_code: |- + name {is} Hedy + {print} Hi I'm name + + # or + + animals {is} rhino, bee, swan + {print} The best animal is... animals {at} {random} + - title: Students forget `{at}` in `{at}` `{random}` + example: + error_text: Like in the example + error_code: |- + birds {is} sparrow, seagull, robin + {print} birds random + solution_text: This problem is solved by adding the word at. + solution_code: |- + birds {is} sparrow, seagull, robin + {print} birds {at} {random} + - title: Students forget to use the `{print}` command when also using the `{at}` `{random}` command + example: + error_text: Or they will sometimes put `{at}` `{random}` at the beginning of the line. + error_code: |- + fruit {is} apple, cherry, banana + fruit {at} {random} + solution_text: Emphasize to your students that you always need a print to print text. + solution_code: |- + fruit {is} apple, cherry, banana + {print} fruit {at} {random} + - title: Students forget to use commas in their lists + example: + error_text: In a list items are seperated with a comma. + error_code: |- + pizzas {is} funghi tonno quattro stagioni + {print} pizzas {at} {random} + solution_text: After each item on your list, there should be a comma + solution_code: |- + pizzas {is} funghi, tonno, quattro stagioni + {print} pizzas {at} {random} + - title: Students try to use `{at}` `{random}` without a list + example: + error_text: For example + error_code: |- + clubs {is} Manchester United + {print} clubs {at} {random} + solution_text: Hedy can't print anything at random, because there is no list to choose from. + solution_code: |- + clubs {is} Manchester United, Bayrn Munchen, FC Barcelona + {print} clubs {at} {random} + - title: Students try to use add/remove without a list + example: + error_text: In the example below 'names' is not a list, but a variable. You cannot add anything to it. + error_code: |- + names {is} Jake + your_name {is} {ask} Who are you? + {add} your_name {to} names + {print} names {at} {random} + solution_text: There has to be a list first, so you have to add a second name to turn names into a list, for example Amy. If you don't want amy on your list, you can use remove to remove it after. + solution_code: |- + names {is} Jake, Amy + your_name {is} {ask} Who are you? + {add} your_name {to} names + {print} names {at} {random} + - title: Students forget to use `{to}`/`{from}` in `{add}`/`{remove}` + example: + error_text: Without to/from the add/remove command won't work. + error_code: |- + adventures {is} story, parrot, dice + choice {is} Which adventure do you like best? + {add} choice + {remove} dice + {print} I love adventures {at} {random} + solution_text: Hedy has to know which list the item should be added to/removed from. + solution_code: |- + adventures {is} story, parrot, dice + choice {is} Which adventure do you like best? + {add} choice {to_list} adventures + {remove} dice {from} adventures + {print} I love adventures {at} {random} + - level: '4' + sections: + - title: Students forget to use quotation marks on both sides of the text + example: + error_text: In this level print and ask need a set of quotation marks.

For example, you can use `{while} game == 'on'` so you can play until the game is over. + Or you can use `{while} sword == 'lost'` so the player can't continue the game until they have found something. + + ### Exercise + The example code shows you how to use the `{while}` loop in a story. Now **think of your own scenario** in which the player has to find something before they can continue. + example_code: | + ``` + keys = 'lost' + {print} 'You are standing in your garden and you have lost your keys.' + {print} 'Where do you want to look for them?' + {print} 'You can choose: tree, flowerbed, rock, postbox' + {while} keys == 'lost' + location = {ask} 'Where do you want to look?' + {if} location == 'flowerbed' + {print} 'Here they are!' + keys = 'found' + {else} + {print} 'Nope they are not at the ' location + {print} 'Now you can enter the house!' + ``` + 18: + story_text: | + We are going to print another story, but now we have to use brackets with `{print}`. + + ### Exercise 1 + Create a story of at least 5 sentences. You don't have to use 'name' just yet. + example_code: | + ``` + {print}('Welcome to this story!') + ``` + story_text_2: | + ### Exercise 2 + We have already prepared an `{input}` for you. First, use the `name` variable in your story. + Then add a second `{ask}` and use that variable as well. + Tip: Remember the commas in a `{print}` between text and variables! + example_code_2: | + ``` + naam = {input}("What's your name?") + {print}('Welcome to this story!') + ``` + add_remove_command: + name: '{add} {to_list} & {remove} {from}' + default_save_name: add_remove_command + description: introducing {add} {to_list} and {remove} {from} + levels: + 3: + story_text: | + ## Add to + You can add items to the list with the `{add} {to_list}` command. To add an item to a list you can simply type: `{add} penguin {to_list} animals` or you can use the `{ask}` command like in the example code. + example_code: | + ``` + animals {is} dog, cat, kangaroo + like {is} {ask} What is your favorite animal? + {add} like {to_list} animals + {print} I choose animals {at} {random} + ``` + story_text_2: | + ## Remove from + If you can add items to a list, of course you can also take them off.

If you want to check two statements, you don't have to use two `{if}`s but can use `{and}` and `{or}`. + + If you use `{and}`, both statements, left and right of the `{and}` need to be true. We can also use `{or}`. Then only one statement needs to be correct. + example_code: | + ``` + name = {ask} 'what is your name?' + age = {ask} 'what is your age?' + {if} name {is} 'Hedy' {and} age {is} 2 + {print} 'You are the real Hedy!' + ``` + ask_command: + name: '{ask}' + default_save_name: ask_command + description: Introduction {ask} command + levels: + 1: + story_text: | + ## The ask command + Now that you can use the `{print}` command, you are ready to learn the next command: `{ask}`. With the `{ask}` command, you can ask a question. Check it out: + example_code: | + ``` + {print} Hello! + {ask} What is your name? + ``` + story_text_2: | + ## The `{echo}` command + If you want the computer to repeat the answer back to you, you can use the `{echo}` command. The answer will be echoed back at the end of the sentence, so in this example after hello. + example_code_2: | + ``` + {print} Hello! + {ask} What is your name? + {echo} hello + ``` + story_text_3: | + ### Exercise + Try out the `{ask}` and `{echo}` commands. Firstly, fill in the blanks to make this program work. + Then ask 2 more questions using the `{ask}` command, after each `{ask}` use an `{echo}` to print the answer on the screen. + example_code_3: | + ``` + _ How are you doing? + _ + ``` + 2: + story_text: | + ## The ask command + Now that we can use **variables** in our codes, we no longer need the `{echo}` command. + We can use variables to store the answers to our questions and this way we can use the answer to multiple questions in our codes. + Check it out: + + This way your code is becoming interactive! + example_code: | + ``` + name {is} {ask} What is your name? + {print} Hello name + age {is} {ask} How old are you? + {print} name is age years old. + ``` + story_text_2: | + ### Exercise + In the previous tab you have practised with setting variables with the `{is}` command. + You have created at least 3 variables and used them with a print command. + Now, instead of setting the variables we want you to make the variables interactive, like we did in our example. + + Copy your code from the previous tab and make the variables interactive by using `{ask}` commands. + example_code_2: | + ``` + favorite_animal {is} {ask} What is your favorite animal? + {print} I like favorite_animal + ``` + 18: + story_text: The final change we will need to make to get Python code is changing + `{ask}` into `{input}`. + example_code: | + ``` + {print}('My name is Hedy!') + name = {input}('What is your name?') + {print}('So your name is ', name) + ``` + blackjack: + name: Blackjack + default_save_name: Blackjack + description: Try to get as close to 21 as you can + levels: + 17: + story_text: | + Blackjack is a simple game of cards in which you have to get as close to 21 points as possible. You get two cards. Each card is worth their numeral value, and the face cards (Jack, Queen and King) are worth 10 points. + The Ace is worth either 1 or 11 points (you can choose). The dealer, your opponent, also gets two cards. + If you want, you can get another card, and its points will be added to your total. The dealer can also choose to take another card. + But be careful not to get more than 21 points, because if you do, you lose! + The player who gets closest to 21, without going over it, wins! + + ### Exercise + In this adventure we code the first part of our Blackjack game. We'll create a function to calculate how many points a card is worth. + + ***Set the variables*** + Start by making a list of all the cards, from 2 to Ace. Next make a list of the face cards, so Jack, Queen and King. Then pick a random card from the list of cards to be card_1. + + ***Create a function to calculate the points*** + Create a function that calculates how many points a card is worth. + All the face cards are worth 10 points, the Ace is worth 11 and all the other cards are worth their numeral. + Return the variable `points` at the end of the function. + + ***Test the function*** + Test if your function is working properly. Finish the first print command by filling in which card you've drawn. Then finish the second line by calling the function with card_1. + Run the code a couple of times. Are you happy with the results? Great! Then you can remove the testing part and move on the the next tab! + example_code: | + ``` + {print} 'BLACKJACK' + + # Set these variables + cards = _ + face_cards = _ + card_1 = + + # Create a function to calculate the points + {define} calculate_points {with} card: + {if} card {in} face_cards: + points = _ + {elif} _ + _ + {else}: + _ + _ points + + # Test your function + {print} 'Your card is a ' _ + {print} 'That is worth ' _ ' points'. + ``` + blackjack_2: + name: Blackjack 2 + default_save_name: Blackjack_2 + description: Blackjack part 2 + levels: + 17: + story_text: | + ### Exercise + In this adventure we code the second part of our Blackjack game. + + ***Paste your code from the previous adventure*** + In the previous adventure you've started a list of variables and created a function to calculate how many points a card is worth. Copy your code and paste it here. Mind that you don't need the testing part, so if you haven't removed that yet, please do so now. + + ***Add more variables*** + You have already set the lists `cards` and `face_cards` and the variable `card_1`. Underneath those variables create 3 more variables: `card_2`, dealer_card_1` and `dealer_card_2`. These variables are all set to a random card from the list of cards. + + ***Add up points*** + To calculate how many points you have scored we call the function with card 1 and we do it again for card 2. Then we add both these scores together to get your total. + Do the same thing for the dealers points, but be sure to use the dealer's cards and not your own! + + ***2 Aces*** + You're doing great! Almost all scores can be calculated now. There is only one exception: 2 Aces. If you get 2 Aces, your total is 12 points and not 22 (because 22 points would be losing!). This of course also goes for the dealer. + + ***Show the score*** + Lastly, you want to tell the program to tell you which cards you have drawn and how many points that is. Then show which cards the dealer has and how many points they have. + + ***Continue in the next tab*** + Great! You have finished this part of the game! Copy your code and go to the next tab to learn how to ask for an extra card and to declare a winner. + example_code: | + ``` + # Paste your code from the previous adventure here + + # Add these variables to the list of variables + card_2 = _ + dealer_card_1 = _ + dealer_card_2 = _ + + # Add up your points + your_points_1 = {call} _ {with} card_1 + your_points_2 = _ + your_total = _ + + # Add up the dealers points + dealer_points_1 = _ + _ + _ + + # 2 Aces + {if} card_1 == 'Ace' {and} _ + your_total = 12 + {if} dealer_card_1 _ + dealer_total = _ + + # Show the score + {print} 'You have drawn a ' _ ' and a ' _ '.

If the card is not an Ace, you can call the function and add the points to your total. + In case the card is an Ace, you can't use the function, because the Ace can be either 1 point or 11 points, depending on how many points you already have earned. + If your total is less than 11, you want the ace to be 11 points (because this is closest to 21). So you add 11 points to your total. + If the total is more than or equal to 11, you want the ace to be 1 point (because you don't want more than 21 points). So you add 1 point to your total. + Lastly, print your new total of points. + + ***Extra card for the dealer*** The dealer can also get an extra card. The dealer doesn't need to be asked, because they always get an extra card if their total is less than 17. + Copy the 'Extra card for you code' and paste it in the dealers section. Then change it to fit the dealer picking an extra card and getting points added to their total. + example_code: | + ``` + # Paste your code from the previous adventure here + + # Extra card for you + hit = {ask} _ + {if} hit == 'yes': + card_3 = _ + {print} _ + {if} card_3 _ 'Ace': + your_points_3 = _ + your_total = _ + {else}: + {if} your_total _ + _ + {else}: + _ + {print} _ + + # Extra card for the dealer + {if} dealer_total < 17 + _ + ``` + blackjack_4: + name: Blackjack 4 + default_save_name: Blackjack_4 + description: Blackjack part 4 + levels: + 17: + story_text: | + In the last 3 adventures you have alsmost created a working blackjack game!

We do that by comparing who has the highest score. Is your total higher than the dealer's total, then you are the winner. If not, the dealer wins. + Lastly, in all other scenarios (e.g. you have more than 21 points and the dealer doesn't, or you both have more than 21 points) you are the loser. + + ***Enjoy the game!*** + Does your game work properly?

In this level you'll learn a better way to echo answers back. + ``` + {print} Welcome at Hedy's + {ask} What would you like to eat? + {echo} So you want + {ask} what would you like to drink? + {echo} So you want + ``` + 3: + story_text: | + In the previous level you've learned what a variable is and how you can use it to make your adventures more interactive. + But... that's not the only thing you can do with variables! You can also use variables to make lists. + And you can even let Hedy pick a random word out of a list, which allows you to make real games! + Take a quick look at the next tab! + 4: + story_text: | + In the previous levels you've been practising with variables, but you may have come across this problem. + You might have tried to run a code like this: + + Of course you wanted to print + + `My name is Sophie` + + but Hedy prints + + `My Sophie is Sophie`. + + In this level this problem is fixed by using quotation marks. + example_code: | + ``` + name {is} Sophie + {print} My name is name + ``` + 5: + story_text: | + In the previous levels you've already learned to use `{at} {random}` which made your games different every time you ran the code. + But it's not really interactive, the player doesn't have any influence on what happens in the game. + + In this level you'll learn the `{if}` command, that allows you to give different responses in your program. This way you can program a secret password for your computer for example. + So let's go to next tab for the new command! + example_code: | + ``` + password {is} {ask} 'What is the correct password?' + ``` + 6: + story_text: | + In the previous level you have practiced with `{ask}` and `{if}`. For example you can ask guests what they would like to eat. + What you can't yet do though, is calculate the price for everyone's dinner. + + This level makes it possible to use addition, subtraction and multiplication in your programs. This way you can calculate the prices in your restaurant, but you could also add a secret code to give your friends and family a discount. + Another option in this level is programming your own maths game, for your little brother or sister to practice their multiplications. + Go see for yourself! + example_code: | + ``` + food_price {is} 0 + drink_price {is} 0 + total_price {is} 0 + {print} 'Welcome to McHedy' + order {is} {ask} 'What would you like to eat?' + {if} order {is} hamburger food_price {is} 5 + {if} order {is} fries food_price {is} 2 + drink {is} {ask} 'What would you like to drink?' + {if} drink {is} water drink_price {is} 0 + {else} drink_price {is} 3 + total_price {is} food_price + drink_price + {print} 'That will be ' total_price ' dollars, please' + ``` + 7: + story_text: | + Great job! You've reached the next level, which means you have practiced with `{if}` and `{else}`. You have probably noticed that your codes are getting longer and longer. + For example if you want to program 'Happy Birthday'. + + That's a lot of code for mainly the same words over and over again. Luckily in the next tab you'll learn a solution with the `{repeat}` command, that allows you to repeat a line of code multiple times. + example_code: | + ``` + {print} 'happy birthday to you' + {print} 'happy birthday to you' + {print} 'happy birthday dear Hedy' + {print} 'happy birthday to you' + ``` + 8: + story_text: | + Now you've learned how to repeat one single line of code. This comes in handy, but it's not always enough. Sometimes you want to repeat multiple lines at once. + This level allows you to group a couple of lines of code, and repeat that little group of lines all at once! + example_code: | + ``` + {repeat} 5 {times} {print} 'In the next tab you can repeat multiple lines of code at once!' + ``` + 9: + story_text: | + Great job! You've reached another new level! In the previous level you've learned to use multiple lines of code in an {if} or {repeat} command. But you can't yet combine the two... + Good news! In this level you will be allowed to put an {if} inside an {if}, or inside a {repeat} command. Putting a block of code inside another block of code is called nesting. ``` Putting a block of code inside another block of code is called nesting. + example_code: | + ``` + answer = {ask} 'Are you ready to learn something new?' + {if} answer {is} yes + {print} 'Great! You can learn to use the repeat command in the if command!' + {print} 'Hooray!' + {print} 'Hooray!' + {print} 'Hooray!' + {else} + {print} 'Maybe you should practice some more in the previous level' + 10: + story_text: | + You're doing great! In the previous levels we still faced a small problem. You have learned to repeat lines, but what if you'd want to slightly change the line. + For example if you want to sing the song 'if you're happy and you know it'. It would look like this: + + If you'd also want the next verse 'stomp your feet', and the next one, and the next one, you'd have to change the code completely. + In this level you'll learn the `{for}` command, which allows you to make a list of actions and repeat the code with another action each time! + Please take a look! + example_code: | + ``` + {repeat} 2 {times} + {print} 'if youre happy and you know it clap your hands' + {print} 'if youre happy and you know it and you really want to show it' + {print} 'if youre happy and you know it clap your hands' + ``` + 11: + story_text: | + You have reached level 11, you're doing great! In the higher levels, Hedy is focussing more and more on teaching you the programming language Python. + In Python there is no `{repeat}` command, but there is a command that works like {repeat}. Are you curious to find out how to say `{repeat}` in Python language? Quickly go on to find out! + 12: + story_text: | + Maybe you have tried using decimal numbers in your restaurant adventure. If you did, you probably noticed that Hedy didn't understand them yet and always rounded off. + From this level on you can use decimal numbers. + example_code: | + ``` + burger = 5 + drink = 2 + total = burger + drink + print 'You have ordered a burger and a drink' + print 'That costs ' total ' dollars please' + ``` + 13: + story_text: | + In the previous levels you've learned how to put two `{if}`commands inside each other. This works fine, but it does give you very long and unhandy codes like this one: + + In this system you have to give both the correct username and the correct password. + In this level you will learn the `{and}` command that will make this code a lot shorter and more understandable! + Check it out! + example_code: | + ``` + username = {ask} 'What is your username?' + password = {ask} 'What is your password?' + {if} username {is} 'Hedy' + {if} password {is} 'secret' + {print} 'Welcome Hedy!' + {else} + {print} 'Access denied' + {else} + {print} 'Access denied!' + ``` + 14: + story_text: | + With the example code you can calculate if you've passed a subject at school (so, a grade of six or higher). + You can see this code is extremely inefficient, due to the very long code in line 5. + All the different grades from 1 to 5 had to be programmed separately. Lucky for you, in this level you'll learn how to do this without this extremely long code! + example_code: | + ``` + first_grade = {ask} 'What score did you get on your first test?' + second_grade = {ask} 'What score did you get on your second test?' + added = first_grade + second_grade + mean_grade = added / 2 + {if} mean_grade = 1 {or} mean_grade = 2 {or} mean_grade = 3 {or} mean_grade = 4 {or} mean_grade = 5 + {print} 'Oh no! You have failed the subject...' + {else} + {print} 'Great! You have passed the subject!' + ``` + 15: + story_text: | + In this game below a code has been made to make sure the player can play on as long as they want... + But the code is ineffective and way too long. Also, what if the player wants to play 101 games instead of 100? + You can't play to infinity? + In this level you will learn a command that makes all of this a lot easier! + example_code: | + ``` + game = 'on' + {for} i {in} {range} 1 {to} 100 + {if} game == 'on' + answer = {ask} 'Do you want to continue?' + {if} answer == 'no' + game = 'over' + {if} answer == 'yes' + {print} 'Ok we will continue' + ``` + 16: + story_text: | + In this level we will grow a bit more towards real Python code. You will also learn how to match two lists together. + This way you can program a code in which the correct animal is matched to the right sound. + Because the two codes below... Are obviously nonsense! + example_code: |- + ``` + animals = 'chicken', 'horse', 'cow' + sounds = 'cluck', 'neigh', 'moo' + {for} animal {in} animals + {print} 'A ' animal ' says ' sounds {at} {random} + ``` + You could also try to make it work this way, but.... + ``` + animals = 'chicken', 'horse', 'cow' + sounds = 'cluck', 'neigh', 'moo' + {for} animal {in} animals + {for} sound {in} sounds + {print} 'A ' animal ' says ' sound + ``` + Note: These codes will not work like this in this level. Head to the next tab to see which parts you need to correct. + 17: + story_text: | + Now we are going to change indentation a little bit. Every time that we need an indentation, we need `:` at the line before the indentation. + + In this level you can also use a new command: `{elif}`. `{elif}` is short for ``{else} {if}`` and you need it when you want to make 3 (or more!) options. + Check it out! + 18: + story_text: | + Congratulations! You have reached the last level of Hedy! The code you have created here can be copied to real Python environments like replit or PyCharm, and you can continue learning there! + Note however that Python can only read English commands, so if you have been using other languages, you will need to switch to English now. + dice: + name: Dice + default_save_name: Dice + description: Make your own dice + levels: + 3: + story_text: | + In this level we can choose from a list. With that we can let the computer choose one side of the die. + Take a look at the games you have in your closet at home. + Are there games with a (special) die? You can also copy it with this code. + For example, the dice of the game Earthworms with the numbers 1 to 5 and an earthworm on it. + + ![Die of earthworms with 1 to 5 and an earthworm on it](https://cdn.jsdelivr.net/gh/felienne/hedy@24f19e9ac16c981517e7243120bc714912407eb5/coursedata/img/dobbelsteen.jpeg) + example_code: | + ``` + choices {is} 1, 2, 3, 4, 5, earthworm + {print} You threw _ {at} {random} ! + ``` + story_text_2: | + ### Exercise + The dice in the example above are dice for a specific game. Can you make normal dice? + Or other special dice from a different game? + example_code_2: | + ``` + choices {is} _ + ``` + 4: + story_text: | + In this level you can also create dice. But this time you can try it yourself, without an example code! + + ### Exercise + Make your own dice in this level. + Tip: If you have no idea how to make dice. Take a peek at your dice from the previous level, but don't forget to add quotation marks. + 5: + story_text: | + We are going to add the `{if}` and `{else}` commands to our dice! + + ### Exercise + Complete the sample code so that the code says "You can stop throwing" once you have thrown an earthworm. It should say "You have to throw again" if you've thrown anything else. + **Extra** Maybe you want to recreate a die from a completely different game. That's fine too! Then make up your own reaction, e.g. 'yes' for 6 and 'pity' for something else. + example_code: | + ``` + choices {is} 1, 2, 3, 4, 5, earthworm + throw {is} choices {at} {random} + {print} 'you have thrown ' throw + _ throw {is} earthworm {print} 'You can stop throwing.' + _ {print} 'You have to throw it again!' + ``` + 6: + story_text: | + You can also make an Earthworm die again in this, but now you can also calculate how many points have been rolled. + You may know that the worm counts 5 points for Earthworms. Now after a roll you can immediately calculate how many points you have thrown. + This is the code to calculate points for one die: + + ### Exercise + Can you make the code so that you get the total score for 8 dice? To do that, you have to copy and paste some lines of the code. + example_code: | + ``` + choices = 1, 2, 3, 4, 5, earthworm + points = 0 + throw = choices {at} {random} + {print} 'you threw ' throw + {if} throw {is} earthworm points = points + 5 {else} points = points + throw + {print} 'those are ' points ' points' + ``` + example_code_2: | + Did you manage to calculate the score for 8 dice? That required a lot of copy and pasting, right? We are going to make that easier in level 7! + 7: + story_text: | + You can also make a dice again in this level. With the `{repeat}` code you can easily roll a whole hand of dice. + + ### Exercise + Try to finish the sample code! **Extra** Think of a game you know that involves a dice and program that using a `{repeat}`. + example_code: | + ``` + choices = 1, 2, 3, 4, 5, 6 + _ _ _ _ _ _ _ + ``` + 10: + story_text: | + ### Exercise + Is everybody taking too long throwing the dice? In this level you can let Hedy throw all the dice at once! + Change the names into names of your friends or family, and finish the code. + example_code: | + ``` + players = Ann, John, Jesse + choices = 1, 2, 3, 4, 5, 6 + _ _ _ _ + {print} player ' throws ' choices {at} {random} + {sleep} + ``` + 15: + story_text: | + ### Exercise + In this level you can create a little game in which you'll have to throw 6 as fast as possible. + We have started the code, it's up to you to get the game to work! + + Firstly, add a `{while}` loop that checks if 6 has been thrown or not. + As long as you haven't thrown 6 already, throw the dice on a random number. + Print what the player has thrown. + Add a try to the amount of tries + Wait a second before you throw again, or - in case you've thrown a 6 - before the game ends. + example_code: | + ``` + options = 1, 2, 3, 4, 5, 6 + {print} 'Throw 6 as fast as you can!' + thrown = 0 + tries = 0 + _ + _ + _ + _ + _ + {print} 'Yes!

Hack the program by removing your name from the list with the `{remove}` `{from}` command. + 4: + story_text: | + With quotation marks you can make your dishwashing program even better. + + ### Exercise + First, fill in right symbols or commands on the blanks to make this example program work. + Did you get it? Great! Now copy your own code from the previous level and make it work in this level by adding quotation marks in the right spots. + example_code: | + ``` + people {is} mom, dad, Emma, Sophie + {print} _ the dishes are done by _ + {sleep} + {print} people {at} _ + ``` + 5: + story_text: | + With the `{if}` you can now have more fun with choice in the program. You can have your program respond to the choice that the computer has made. + ### Exercise + Can you finish the code so that it prints 'too bad' when it is your turn and otherwise 'yes!'? + Don't forget the quotes! + example_code: | + ``` + people {is} mom, dad, Emma, Sophie + dishwasher {is} people {at} {random} + _ dishwasher {is} Sophie {print} _ too bad I have to do the dishes _ + _ {print} 'luckily no dishes because ' _ ' is already washing up' + ``` + 6: + story_text: | + How often is everyone going to do the dishes?

That's not fair! + To create a fairer system you can use the `{remove}` command to remove the chosen person from the list. This way you don't have to do the dishes again until everybody has had a turn. + + Monday and Tuesday are ready for you! Can you add the rest of the week? + And… can you come up with a solution for when your list is empty? + example_code_2: | + ``` + people = mom, dad, Emma, Sophie + dishwasher = people {at} {random} + {print} 'Monday the dishes are done by: ' dishwasher + {remove} dishwasher {from} people + dishwasher = people {at} {random} + {print} 'Tuesday the dishes are done by: ' dishwasher + {remove} dishwasher {from} people + ``` + 7: + story_text: | + With the `{repeat}` you can repeat pieces of code. You can use this to calculate who will be washing dishes for multiple days! + ### Exercise + Use the `{repeat}` command to decide on who needs to wash the dishes for an entire week. Each blank needs to be filled with one command or number! + **Extra** Can you think of other tasks in the house? Adapt the code so it decides on three household chores. Do not forget to print what tasks it concerns! + example_code: | + ``` + people = mom, dad, Emma, Sophie + {repeat} _ _ {print} 'Dishwashing will be done by ' _ _ _ + ``` + 10: + story_text: | + In this level you can make a schedule for the whole week in an easy way! + + ### Exercise + Add a second chore, such as vacuuming or tidying up, and make sure it is also divided for the whole week. +
**Extra** The program is not fair, you can be unlucky and wash up all week. How could you make the program more fair? + example_code: | + ``` + days = Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday + names = mom, dad, Emma, Sophie + {for} day {in} days + {print} names {at} {random} ' does the dishes on ' day + ``` + elif_command: + name: '{elif}' + default_save_name: elif + description: '{elif}' + levels: + 17: + story_text: | + In this level you can also use a new command: `{elif}`. `{elif}` is a combination of the keywords `{else}` and `{if}` and you need it when you want to make 3 (or more!) options. + Check it out! + example_code: | + ``` + prizes = ['1 million dollars', 'an apple pie', 'nothing'] + your_prize = prizes[{random}] + {print} 'You win ' your_prize + {if} your_prize == '1 million dollars' : + {print} 'Yeah!

With `{for}` you can make a list and use all elements. + `{for}` creates a block, like `{repeat}` and `{if}` so all lines in the block need to start with 4 spaces. + example_code: | + ``` + animals = dog, cat, blobfish + {for} animal {in} animals + {print} 'I love ' animal + ``` + story_text_2: | + ### Exercise + Finish this code by adding `{for} action {in} actions` to line 2. + example_code_2: | + ``` + actions = clap your hands, stomp your feet, shout Hurray! + _ + {repeat} 2 {times} + {print} 'If youre happy and you know it, ' action + {sleep} 2 + {print} 'If youre happy and you know it, and you really want to show it' + {print} 'If youre happy and you know it, ' action + {sleep} 3 + ``` + 11: + story_text: |- + In this level, we add a new form of the `{for}`. In earlier levels, we used `{for}` with a list, but we can also use `{for}` with numbers. + We do that by adding a variable name, followed by `{in}` `{range}`. We then write the number to start at, `{to}` and the number to end at. + + Try the example to see what happens! In this level again, you will need to use indentations in lines below the `{for}` statements. + example_code: | + ``` + {for} counter {in} {range} 1 {to} 10 + {print} counter + {print} 'Ready or not. Here I come!' + ``` + 17: + story_text: | + Now we are going to change indentation a little bit. Every time that we need an indentation, we need `:` at the line before the indentation. + example_code: | + ``` + {for} i {in} {range} 1 {to} 10: + {print} i + {print} 'Ready or not, here I come!' + ``` + 18: + story_text: | + Lastly, we'll turn `{for} i {in} {range} 1 to 5` into real Python code, like this: + example_code: | + ``` + {for} i {in} {range}(1,5): + {print} (i) + ``` + fortune: + name: Fortune teller + default_save_name: Fortune Teller + description: Let Hedy predict the future + levels: + 1: + story_text: | + Have you ever been to a carnival and had your future predicted by a fortune teller? Or have you ever played with a magic eight ball? + Then you probably know that they can't really predict your future, but it's still fun to play! + + In the upcoming levels you can learn how to create your own fortune telling machine! + In level 1 you can start off easy by letting Hedy introduce herself as a fortune teller and let her `{echo}` the players' answers. + Like this: + example_code: | + ``` + _ Hello, I'm Hedy the fortune teller! + _ Who are you? + _ Let me take a look in my crystal ball + _ I see... I see... + _ Your name is + ``` + story_text_2: | + ### Exercise + Copy the example code into your input screen and fill in the blanks to make the code work. + **Extra** Change the code and let the fortune teller not only predict your name, but also your age, your favorite sports team or something else about yourself. + 3: + story_text: | + In the previous levels you've created your first fortune telling machine, but Hedy couldn't really predict anything, only `{echo}`. + In this level you can use a variable and the `{at} {random}` command to really let Hedy choose an answer for you. Check out this code for instance: + example_code: | + ``` + {print} I’m Hedy the fortune teller! + question {is} {ask} What do you want to know? + {print} This is what you want to know: question + answers {is} yes, no, maybe + {print} My crystal ball says... + {sleep} 2 + {print} answers {at} {random} + ``` + story_text_2: | + ### Exercise + Now, Hedy can only answer yes, no or maybe. Can you give Hedy more answer options, like 'definitely' or 'ask again'. + 4: + story_text: | + ### Exercise + We have removed all the quotation marks from this example code, can you add them in all the right places? + + ### Exercise 2 + Go back to the previous level and copy your fortune teller code. Make the code work in this level by adding quotation marks in the right spots. + example_code: | + ``` + _ Add the quotation marks to this code _ + {print} Im Hedy the fortune teller! + question {is} {ask} What do you want to know? + {print} This is your question: question + answers {is} yes, no, maybe + {print} My crystal ball says... + {sleep} 2 + {print} answers {at} {random} + ``` + 5: + story_text: | + ### Exercise + In the example code you see how to make a fortune teller program that allows you to tip the odds in your favor. This cheating program always tells you that you will win the lottery, but your friends will never win. + + Use this to make your own program, be creative! For example you could create a code that predicts that: + * your favorite sports team will beat all the competitors! + * your favorite movie will be chosen for movie night! + * you win tickets to your favorite show! + * you are the fairest of them all, like Snow White's magic mirror. + Let your imagination do the work! + + Your program has to exist of at least 10 lines of code and need to have at least one `{if}` and `{else}` command. + example_code: | + ``` + friends {is} Jordan, Lucy, Dave + {print} 'I can predict if you will win the lottery tomorrow!' + person {is} {ask} 'Who are you?' + good_answer {is} Hurray! You win!, You will definitely win!, We have a winner! + bad_answer {is} Bad luck! Try again!, Another person will win, You lose! + {if} person {in} friends {print} good_answer {at} {random} + {else} {print} bad_answer {at} {random} + ``` + 6: + story_text: | + In this level you can use math in your predictions as a fortune teller. This allows you to make up (silly) formulas to calculate the future. + For example you could calculate how rich you'll get or how many kids you will have when you grow up. + + + + ### Exercise + Can you think of your own (silly) fortune telling machine? + example_code: | + ``` + {print} 'I am Hedy the fortune teller!' + {print} 'I can predict how many kids youll get when you grow up!' + age = {ask} 'How old are you?' + siblings = {ask} 'How many siblings do you have?' + length = {ask} 'How tall are you in centimetres?' + kids = length / age + kids = kids - siblings + {print} 'You will get ...' + {sleep} + {print} kids ' kids!' + ``` + 7: + story_text: | + ### Exercise + Finish this program that tells you if your crush loves you back or not. + example_code: | + ``` + {print} 'I have a flower with magic petals' + {print} 'If you pick the petals the flower will tell you if your crush loves you back' + amount = {ask} 'How many petals do you want to pick?' + options = they love you, they love you not + _ _ _ _ options {at} {random} + ``` + 8: + story_text: | + In the next example you can have your fortune teller ask multiple questions and also print them! + + ### Exercise + Can you fill in right command on the blanks? + example_code: | + ``` + {print} 'I am Hedy the fortune teller!' + {print} 'You can ask me 3 questions.' + answers = yes, no, maybe + _ _ _ + question = {ask} 'What do you want to know?' + {print} question + {sleep} + {print} 'My crystal ball says... ' answers {at} {random} + ``` + 10: + story_text: | + In this level you'll learn how to program the game MASH (mansion, apartment, shack, house). In this game you can predict for all the players at once, what their future will look like. + + ### Exercise + Fil in the blanks by using the new command that you've learned this level. + example_code: | + ``` + houses = mansion, apartment, shack, house + loves = nobody, a royal, their neighbour, their true love + pets = dog, cat, elephant + names = Jenna, Ryan, Jim + _ + {print} name ' lives in a ' houses {at} {random} + {print} name ' will marry ' loves {at} {random} + {print} name ' will get a ' pets {at} {random} ' as their pet.' + {sleep} + ``` + 12: + story_text: |- + From level 12 on, you will also have to use quotation marks in lists, before and after each item. + + ### Exercise + Add two predictions to the list + example_code: | + ``` + fortunes = 'you will slip on a banana peel', _ + {print} 'I will take a look in my crystal ball for your future.' + {print} 'I see... I see...' + {sleep} + {print} fortunes {at} {random} + ``` + functions: + name: functions + default_save_name: functions + description: functions + levels: + 12: + story_text: | + In this level you'll learn how to use **functions**. A function is a block of code you can easily use multiple times. Using functions helps us organize pieces of code that we can use again and again. + To create a function, use `{define}` and give the function a name. Then put all the lines you want in the function in a indented block under the `{define}` line. + Leave one empty line in your code to make it look nice and neat. Great job! You have created a function! + + Now, whenever we need that block of code, we just use {call} with the function's name to call it up! We don't have to type that block of code again. + + Check out this example code of a game of Twister. The function 'turn' contains a block of code that chooses which limb should go where. + + ### Exercise + Finish this code by setting the 2 variables chosen_limb and chosen_color. + Then, choose how many times you want to call the function to give the twister spinner a spin. + + ### Exercise 2 + Improve your code by adding a variable called 'people'. Use the variable to give all the players their own command in the game. + For example: 'Ahmed, right hand on green' or 'Jessica, left foot on yellow'. + example_code: | + ``` + sides = 'left', 'right' + limbs = 'hand', 'foot' + colors = 'red', 'blue', 'green', 'yellow' + + {define} turn + chosen_side = sides {at} {random} + chosen_limb = limbs _ + chosen_color = colors _ + {print} chosen_side ' ' chosen_limb ' on ' chosen_color + + {print} 'Lets play a game of Twister!' + {for} i {in} {range} 1 {to} _ + {call} turn + {sleep} 2 + ``` + 13: + story_text: | + Now that you've learned how to use functions, you'll learn how to use a function with an argument. + An **argument** is a variable that is used within a function. It is not used outside the function. + + For example in this code we've programmed the first verse of the song 'My Bonnie is over the ocean'. + In this example code the argument 'place' is used. Place is a variable that is only used in the function, so an argument. + To use 'place' we have placed `{with} place` after `{define} song`. + When the function is called, the computer will replace the argument 'place', with the piece of text after `{call} song {with}`. + + ### Exercise + The next verse of this song goes: + + ```not_hedy_code + Last night as I lay on my pillow + Last night as I lay on my bed + Last night as I lay on my pillow + I dreamed that my Bonnie is dead + ``` + + Can you program this verse in the same way as the example? + example_code: | + ``` + {define} song {with} place + {print} 'My Bonnie is over the ' place + + {call} song {with} 'ocean' + {call} song {with} 'sea' + {call} song {with} 'ocean' + ``` + 14: + story_text: | + In the previous levels you have learned to create functions and use arguments with them. Another great use of a function is to let it calculate something for you. + You can give the function a calculation and it will give you the answer of the calculation. This answer is called a **return value**. + + For example, in this code the function calculate_new_price will calculate the new price of any item. It will give you the new price as a return value. + + ### Exercise + Finish this code. We have already made the variable new_price for you, you only need to set it. + You should finish the line of code by calling the function that calculates the new price. + example_code: | + ``` + {define} calculate_new_price {with} amount, percentage + percentage = percentage / 100 + discount_amount = amount * percentage + {return} amount - discount_amount + + old_price = {ask} 'How much is on the price tag?' + discount = {ask} 'What percentage is the discount?' + + new_price = _ calculate_new_price {with} old_price, _ + {print} 'The new price is ' new_price ' dollar' + ``` + 18: + story_text: | + Let's make functions the Pythons way! To define a function, we no longer use: + + `{define} name_function {with} argument_1, argument_2:` + + but we use: + + `{def} name_function(argument_1, argument_2):`. + + + If you don't want to use arguments, you just leave the space between the parantheses empty. + To call a function, we don't need the `{call}` command anymore. You just type the name of the function. + example_code: | + ``` + {def} calculate_score(answer, correct_answer): + {if} answer == correct_answer: + score = 1 + {elif} answer == '?': + score = 0 + {else}: + score = -1 + {return} score + + answer = {input} ('Where can you find the Eiffel Tower?') + correct_answer = 'Paris' + score = calculate_score(answer, correct_answer) + {print} ('Your score is...

Now make an empty list for guessed_letters as well. + Then we fill in how many mistakes were made. At the start of the game, this should be 0. + The variable `amount_letters` tells us how many letters are in the answer. Ask Player 1 to tell us how many letters their word has. + Lastly we tell the computer if the game is over. We use the variable `game_over` and set it to `False`. + + ***Choosing the answer*** We want Player 1 to be able to choose the answer. We'll ask them, as many times as necessary, what the next letter is. + Then we add that letter to the answer. Lastly, we add an empty _ to the list of guessed letters, so we get as many _s as there are letters in the answer. + + ***Player 2's turn*** + Tell Player 2 its their turn. Then tell Player 2 how many letters there are in the answer.

Fill in the while command accordingly. Now, Player 2 is allowed to guess a letter, so ask Player 2 to guess a letter. + We need to check if their answer is correct, so check if their `guess` is (somewhere) in the (list) `answer`. Then we let the computer figure out which of the letter(s) is the guess. We have already programmed that part for you. + Next we want to compliment the player for finding a correct letter and we want to print the list `guessed_letters`, so the player can see their progress. + + The next part we're going to program is what happens when the player has guessed all of the letters. So if their list of `guessed_letters` is the same as our list `answer`. + If the lists are the same, congratulate Player 2 with their victory and set the variable `game_over` to `True`. + + Next we'll program what happens when Player 2 guesses wrong (so the `{else}` command). First, tell the player that their guess was wrong. Then increase the `mistakes_made` variable by 1. + + For the last part we'll program what happens when Player 2 has made 10 mistakes. We'll print that Player 1 has won the game. Then we'll print the correct answer. And finally, we'll set our `game_over` variable to `True`, so the game stops. + + ***Go to the next tab*** Amazing work!

We have already made step 1 for you. + + ***Test the function*** Test the function by calling the function with 10. If you are happy with the function, remove the line that calls the function for now. We will call the function when the player makes a mistake. + + ***Paste your hangman game under your function*** Go back to the previous tab and copy your hangman game. Paste the game underneath your function. + + ***Call the function when the player makes a mistake*** Under the line `mistakes_made = mistakes_made + 1` we will call the function.

In this level you will be allowed to put an `{if}` inside an `{if}`, `{repeat}` inside a `{repeat}` command and in eachother. + Give it a try! + example_code: | + ``` + {repeat} 3 {times} + order = {ask} 'What would you like to order?' + {if} order {is} pizza + {print} 'Yammie' + {else} + {print} 'pizza is better!' + ``` + repeat_command_2: + name: '{repeat} 2' + default_save_name: repeat_command_2 + description: '{repeat} command 2' + levels: + 7: + story_text: | + ## Repeat with other commands and with variables + You have practiced the `{repeat}` command in combination with the `{print}` command now, but did you know you could also use other commands with `{repeat}` ? + In this example code you can see that `{repeat}` can also be used with an `{ask}`, `{if}` or `{else}` command. + example_code: | + ``` + {repeat} 2 {times} answer = {ask} 'Did you know you could ask a question multiple times?' + {if} answer {is} yes {repeat} 2 {times} {print} 'You knew that already!' + {else} {repeat} 3 {times} {print} 'You have learned something new!' + ``` + story_text_2: | + Another interesting thing you can do with the `{repeat}` command is using variables to set the amount of times something should be repeated. In the example code you can see that we first ask the person how old they are. + Then, in line 3, the question is repeated 'age' times. So we have used the variable 'age' with the `{repeat}` command. + example_code_2: | + ``` + {print} 'Yay! It is your birthday!' + age = {ask} 'How old are you now?' + {repeat} age {times} {print} 'Hip Hip Hurray!' + ``` + 8: + story_text: | + ### In the block or not? + In this level you have to think carefully which lines of code should be in the block and which shouldn't. + For example: If you want to sing the song *the muffin man*. You only want the line with 'the muffin man' to be repeated twice. + This means the last line shouldn't start with indentation as it doesn't belong to the block. + If you do start the last line with indentation the song will turn out wrong. + + ### Exercise + Each line in the example code starts with a blank. Remove the blanks and try to figure out which line need indentation and which don't to make the muffin man song. + example_code: | + ``` + _ {print} 'Do you know the muffin man?' + _ {repeat} 2 {times} + _ {print} 'The muffin man' + _ {print} 'Do you know the muffin man, who lives on Drury Lane?' + ``` + restaurant: + name: Restaurant + default_save_name: Restaurant + description: Create your own virtual restaurant + levels: + 1: + story_text: | + In level 1 you can make your own virtual restaurant and take your guests' orders. + story_text_2: | + ### Exercise + Copy the example code into your input screen by clicking the yellow button. + Firstly, fill in the correct command on the blanks to make to code work properly. + Then add at least 4 more lines of code to the restaurant program. + Ask the costumer what they would like to drink and ask if they want to pay with cash or card. + Lastly, think of a nice way to say goodbye to your costumer. + example_code_2: | + ``` + {print} Welcome to Hedy's restaurant 🍟 + _ What would you like to order? + {echo} So you would like to order + {print} Thank you for your order! + {print} It's on its way! + ``` + 2: + story_text: | + In level 2 you could expand your restaurant by using variables.

This list is filled with 9 dots, since there are no x's and o's yet at the start of our game. + + ***Create a function that prints the field*** Firstly, clear the screen so the old playing fields will be removed. Then we print the first line of our Tic Tac Toe field. This line constists of the first 3 spots in our list field. + We have already programmed this line for you. Now finish the field by printing spot 4, 5, and 6 on the second row and spot 7, 8 and 9 in the third row. + + ***Call the function that prints the field*** Now call the function. +
+ Run the code. Your output should look like this: +

Please add the colons in the correct spots. + + ***Create a function that detects if someone's won*** We have started the function for you, paste it under the function `print_field` and finish the function. You can see that this first piece of code checks to see if spot 1, 2 and 3 are the same, because if they are you have 3 in a row. + It also checks if they are not a dot, because if they are, the line might have the same symbols on them, but that's just because it's still empty. + If all these conditions are met, the game is over and the winner is printed. + Finish this function with all possible ways to win. This means you have to make this for the other 2 rows, 3 columns and 2 diagonals. + If you've finished all the other options, the function should return the variable `game_over` so we can use it in our game. + + ***Call the function in the game*** Go to the line `game_over = {ask} 'Did you win?'` and change it to `game_over = {call} detect_winner {with} field, sign`.

Now you'll learn how to create the game! + + ### Exercise + ***Paste your code*** Start by pasting your code from the previous adventure here. + + ***Add variables*** Underneath your list called `field` we'll add 2 more variables that we'll need to program the game. + The variable `game_over` tells us if the game is over, and should be 'no' at the start of the game. + The variable `sign` tells us if it's the turn of player x or player o. Set the variable to 'x'. + + ***The game*** First use a {while} command, to make sure the game keeps on playing the variable while game_over is set to no. + During the game, we first ask the player which spot they choose. Then we change the field with the number they chose into their sign. + Then we print the field again and we ask the player if they've won yet. Lastly we want to switch whose turn it is, so if the sign is 'x' it should be 'o' and the other way around. + + ***Test your game*** Does your game work? Great, have fun playing the game! If not, use the ladybug button to debug your code. + You might have noticed one mistake in the code though, you can steal the other player's spot!

You can create your own classes, lesson plans and follow how kids are doing. + * You do not need to know a lot of programming if you begin, Hedy works step by step, also for you! + * You can use Hedy in your native tongue because it has been translated into many other languages! + * Every kid can programme!! Hedy is especially helpful for kids who have vision problems because it can read material aloud to you without the need for a mouse. + * We are here to help, you can find us for example on [Discord](https://discord.gg/8yY7dEme9r) or you can [email-us](hello@hedy.org). +- title: Teachers about Hedy + text: |- + Various teachers worldwide have expressed their passion for Hedy, as some have shared with us: + + *Incredibly inspiring! Super good way to make programming a lot more accessible for yourself, but also for students. Very fun to play with and a lot of potential to use with the students. I think it is a very nice tool! I believe this is a valuable way for children to start learning programming. Python and coding have always been very exciting, because the barrier to learning is very high. Now everything is a bit lower and it was explained that it can actually be very easy. I enjoyed seeing how Hedy tries to make programming as accessible as possible for users!* + Netherlands: Mathematics teachers in training (secondary school) + + *Simple interface and good examples.* Teacher: 3rd - 6th grades (elementary) + + *Multilingual programming and just the gradual programming concept itself.* US: middle school, 6th-8th grade + + *The gradual nature of introducing programming.* Australia: High school + + *Continues automatically.* Netherlands: 2 HAVO-VWO + + *Both that the explanation can be in Dutch (and the code in English), and that it builds up with more and more possibilities.* Netherlands: Plus class group + + *But Hedy and its gradual levels...what an idea, I wanted to personally thank you for creating this. I cannot thank you enough. Also, I have never seen the level of engagement and enthusiasm of my students, as I have seen with Hedy. We have covered till level 5, and plan to spend one more week on it in classes and labs, before starting Python.* Pakistan + + *The 'realness' of programming, it resembles how it is in reality.* Netherlands: Plus class group 4 to 8 + + *Step-by-step activities. Fun activities.* Netherlands: 1e All levels, 2e VWO/HAVO 2e VWO +, 3e HAVO 3e VWO + + *I really like Hedy very much and it is also nicely set up, which makes it good to use in primary school. Hedy's gradual approach works very well. The short explanation at the beginning of each level and the short example programs help to give the children a quick insight into what is new in the chosen level. The different assignments that the children can choose also work very well. You see the children choose assignments that appeal to them and they then get to work with them, through the levels. Hedy is great fun for children who are good at programming and want to get a taste of a real programming language. It is good preparation for secondary school as soon as more ICT education is given there.* Netherlands: Oegstgeest Montessori school + + *The construction is so good.* Netherlands: Lower secondary school HAVO-VWO + + *I can keep the pace of the class.* Netherlands: group 7 en 8 + + ![Felienne teaching kids](/images/teacherfeedback/Fkids1.JPG) *Felienne teaching kids* + + + ![Kids learning about Hedy](/images/teacherfeedback/Fkids2.JPG) *Kids learning about Hedy* +teacher-guide: +- title: Introduction + key: intro + subsections: + - title: What's Hedy? + text: |- + Hedy is a textual programming language, specifically developed for (pre-)teens (10 to 15 years old). + In contrast to programming languages for kids, like Scratch, Hedy doesn't use code blocks but textual code. + So with Hedy you'll learn how to type code like the real programmers do, but in small steps with playful exercises. + This way Hedy can function as a stepping stone to real programming languages like Python in an accessible and mostly fun way! + If you want to know more, you can watch this video about the development of Hedy as a programming language. + - title: Target audience + text: |- + Hedy is developed with middle school and junior high school students in mind (ages 10 - 15). + It's important for the students to be able to read well. We recommend not to start with Hedy before the students have achieved at least a 3rd grade reading level. + Students (and teachers!) don't need any programming experience before starting with Hedy. + - title: How does Hedy work? + text: |- + Hedy is divided into levels, in which new commands are taught. Each level contains a variety of adventures to practice the newly learned commands. + As a teacher, you get to decide which adventures are available for your students. Will they be making a restaurant, a calculator or a haunted house this level? Within each level, the adventures are arranged from easiest to hardest. + So your students keep getting challenged. The adventures can be done by the students individually, or you can use them in a classical instruction. + + The adventures also include a code example, to make sure the less digitally informed teachers are able to use Hedy too! + Of course Hedy also caters to the creative teachers that love to make their own lessonplans and adventures! + + After programming all the adventures of a certain level, your students can test their knowledge in the quiz. + You can track your students' work and their progress on the class page. + - title: Devices + text: |- + Hedy is web-based, which means it works on any device with a browser (Google Chrome, Firefox, Edge etc), so laptops, Chromebooks, tablets and even smartphones are suitable to use Hedy. + There's no need to download anything before working with Hedy, just go to the website and you're all set! + - title: The Hedy Community + text: |- + All Hedy teachers, programmers and other fans are welcome to join our Discord server. This is the ideal place to chat about Hedy: we have channels where you can show your cool projects and lessons, channels to report bugs, and channels to chat with other teachers and with the Hedy team. + Here you can find a video on how to join the Discord Community. + - title: Hedy and the GDPR + text: |- + Organizations in the EU have to comply with the GDPR (General Data Protection Regulation) when processing personal data. + Because this is a complex issue for many schools, you can use all Hedy programming functionalities without sharing personal data. + The easiest way to do this is to use Hedy without creating accounts for the teacher and students. Without accounts, all functionality is available, with the exception of personalizing levels, saving students' programs and viewing their progress. That is limiting, but there are schools that use Hedy in that way. + + A second way is for a teacher to create an account with an email address without personal data, for example "docent25@email.com". Apart from an email address, which is only required to reset your password, you do not need to share any information when you create a teacher account. + With a teacher account, you can create anonymous accounts for students, e.g. rainbow-student1, rainbow-student2, etc (See 'Teaching preparations' for a detailed manual). This way you can use all functionality of Hedy, including saving progress, without sharing personal data of yourself or your students. + + If the above is not sufficient for your context, we can sign a processing agreement for the processing of your personal data. +- title: Tutorial + key: tutorial + subsections: + - title: Tutorial + text: Do you want to follow the tutorial (again)?

On this page you'll find everything you'll + need to teach with Hedy, like your classes, your adventures and slides. All + the functionalities of the for teachers page are explained below. + - title: Creating a Class + text: |- + As a teacher, you can create a class for your students. In this class you can see the students' accounts and their programs and you could monitor their progress. + This video shows you how to quickly create a class in Hedy. + - title: Duplicate a class + text: |- + Are you teaching multiple classes? Then you don't have to customize each class individually. Simply make a class, costumize the class (see "Customize your Class" to learn how) and then duplicate this class as many times as you want. + You can duplicate the class on the 'For Teachers' page. If you duplicate a class, all the class settings are duplicated as well. This means that all the levels and adventures you've mande unavailable for the first class will now be unavailable for the new class(es) as well. + The student accounts and second teacher accounts in your class will not be duplicated into the new class. + - title: Add a second teacher + text: |- + Are you not the only teacher that teaches your class? Then you can now add another teacher to the class. Go to the 'For teachers' page and click on the class. Then choose 'Invite a teacher' and fill in the username of your colleague. + Your colleague will get an invitation on their account to join your class. They can see that invitation message by clicking on their username in the upper right corner of the screen and selecting 'My account'. + Once the other teacher accepts the invitation they can customize the class as well. + To remove a second teacher from your class, go to the class page and remove the second teacher. The teacher who's created the class cannot be removed. + - title: Customize your Class + text: |- + You can customize your class and choose which adventures are available for your students. This way your students won't be overwhelmed by the amount of adventures and levels, and they can specifically focus on the adventures you'd like them to practice with. + Click on your class on the for teachers page and choose 'customize class'. On this page you can select levels, set opening dates, unlock level thresholds and more. + + **Select and order adventures** + + In this section you can select and order adventures. The pink tabs are adventures with new commands. The gray tabs are regular adventures. To rearrange the order of the adventures, you can drag the tabs. However, we do advise you to use the regular order of adventures as the Hedy team made sure the adventures go from easiest to hardest. + If you want to remove an adventure for your students, simply click the cross on the adventure's tab. + + If you want to add adventures, for instance your own adventure or an adventure you accidentally removed, use this menu to add the adventure to your students' adventures. Simply click the adventure you want to add and it (re)appears in the line of adventures. To undo all your changes to the adventures, click 'Reset'. + + **Opening dates** + + With this feature you can set opening dates for the levels. This way you can make a lesson plan before your course begins and not worry about opening new levels each week. In the image above the first level is opened directly, the second will open the 23th of september, and the 3rd level the week after. The other levels are closed. + Don't want to set opening dates? No problem, just leave this section blank. + + **Unlock level thresholds** + + This featue allows you to set a threshold for your students' quiz grade, before they can continue to the next level. For example, if you enter "80" your students have to score at least 80% on the quiz before they are allowed to go to the next level. If they haven't met the threshold, they are not allowed to continue and have to retake the quiz. + Don't want to use the threshold? No worries, just keep this section blank. + + + **Other settings** + + There are some other setting that could be usefu to you aswell. Our first extra setting is 'Mandatory developer's mode'. In developers mode the students only see their input and output screens and the run button. The adventures are hidden and there are no cheatsheets available. This might come in handy in a test situation. + If this option is not selected the developer's mode is available for students too as a voluntary option. + + If you want all your students to be visible in de class highscore, you can select the second option. + With all the other options you can choose to hide some functions or content for your students, this might help them focus more. + + **Save** + + Don't forget to save your changes when you're done customizing your class. + - title: Student Accounts + text: |- + To add students to your class go to the class page by clicking in the class name on the 'for teachers' page. Then click 'add students'. There are 2 ways to let your students join your class: You can create accounts for them, or they could create their own accounts. + + **You create accounts for your students** + The easiest way to add students to your class is by creating an account for them. This can be done by clicking the 'create student accounts' button and filling in the usernames and passwords for them. + The students can login with the username and password that you chose. Afterwards, they can change their username or password if they'd like and they'll still remain in your class. + This video shows how to add students to your class in the quickest and easiest way. + + **Students make their own accounts** + Your students can also go to the Hedy website and create their own accounts, just like you did. To get them into your class, they simply have to click the invite link. + You can find the invite link on the class page and send it to your students. Mind that your students have to be logged in to Hedy when they click the link, in order to make it work smoothly. + You can also manually invite a student to your class with the button 'Invite by username'. + - title: Setting preferred language + text: |- + When students create profiles they are supposed to choose a 'preferred language'. Hedy will always be loaded in this selected language. + Changing this language can always be done later on by navigating to 'My account' and 'My personal settings' again. + + **For non-English speakers** + Not only can you change the language of the adventures to your own language. You can also choose which language the keywords (for example 'print' or 'ask') should be in. + This way you can teach your students to code with English keywords, but you can also let them program in their own language. For example, Dutch students can use the command 'vraag' instead of 'ask'. + If a student wants to switch languages, they can click the keyword switcher. It will switch the keywords from English to the preferred language and back. + Fun fact! Students are allowed program in both English and their own language at the same time! So, if they have trouble remembering some keywords in English, but easily remember other ones they can use both at the same time. + + + **Video** + This video show you how to set a preferred language and change the keywords to you preferred language as well. + - title: Storing programs + text: |- + When you are logged in, you'll see My programs next to your profile icon. + This option exists for your students too. In My programs you can find all the programs that you've worked on. + By default, programs will be saved to 'My programs' when you run the code, and every 10 seconds, under their default name + and their level (for example: Story 5). If you want to store a program under a new name, just type the new name in the name bar. + Currently, only one program can be saved per level, per tab. + + You (and your students) can also share programs using the share button next to program names. + These programs will be posted on our explore page, for everybody to see and use. + If you want to unshare your program, go to 'My programs' and click 'Unshare'. + + The paper plane icon can be used to hand in programs to the teacher of a class. Programs that have been handed is will no longer be editable. +- title: Teaching with Hedy + key: teaching + subsections: + - title: Teaching with Hedy + text: |- + Hedy contains a lot of different levels that each teach a different new skill. We recommend to teach one level per lesson. + This gives your students the time to fully grasp a new command or concept and practice with it, before moving on to the next level. + We use this structure in our lessons: Introduction, New concepts and commands, let's get to work, puzzles and quizzes. + - title: Slides + text: |- + When giving instructions you might want to use our slides. Our slides are available on the 'For teachers' page. There is a set of slides for each level. In the slides all the new commands for that level are explained. We have aimed to explain why these changes are nessecary or how the new commands come in handy. + We also give some examples of how the new commands can be used. You could of course also use your own slides, or just open Hedy and show your students around the website. Whichever you prefer to give the best Hedy lessons! + - title: Introduction + text: |- + You can start your lessons by activating your students' prior knowledge: What do they already know about the subject, what did they learn in the previous lesson and which mistakes did they make that they've now learned from? + This way all the previously learned commands and frequently made mistakes are fresh in your students' memories, when you start introducing the new lesson. + - title: Introduction of new concepts and commands + text: |- + The new concepts and commands can be very hard for some students to fully understand. + That's why it's of importance to model the proper use of the new commands to your students. + Especially in the lower levels, where some students have no experience with programming at all, it can be hard for them to understand the new abstract concepts. + Showing a lot of examples makes an abstract concept (for instance: 'What is a variable?') more recognizable and easier to understand ('Look, the variable pet changed into dog'). Our slides could help you with that. + - title: Let's get to work + text: |- + Each level contains different adventures that you can find in the pink tabs. The first pink tab explains the new commands in this level. + The following tabs are adventures that the students can try out and make their own. + The adventures are arranged from easiest to hardest, so we recommend to start on the left and your your way to the right. + The last tab 'what's next' gives a little teaser of what you'll learn in the next level. Of course, you can select the adventures you want your students to do for each level. + They don't always have to make every adventure. Every adventure contains an example code, that the students can try out with the green button. + The example code gets copied to the workfield, where the students can try out the code and adjust it to make it their own. + Stimulate your students to turn the example code into their own projects by adding their own ideas and making their own variation of the adventure. + - title: Quizzes and puzzles + text: |- + To test whether your students have picked up all the new info in the level, you can let them take the quiz. + The quiz contains 10 multiple choice questions about the new concepts and command to that level. + Not every level has a quiz yet, as we are still building the quizzes. + Some levels also contain puzzles. Puzzles show the students a couple of line of code that the students have to put in the right order. + + This video shows the quizzes and puzzles. + - title: Evaluation + text: |- + Round up your lesson by having a brief evaluation. What did the students learn? Which hardships did they come across? + How did they learn from their mistakes? And of course: What did they create? + Students are often very proud of their own creations, so it's nice to save a little time and give your students the opportunity to show their work to their classmates. +- title: Teacher Statistics + key: teacher_statistics + subsections: + - title: Live Dashboard + text: |- + If you would like to keep track of your students' progress, you can make use of the live dashboard. You can find the live dashboard by clicking 'Live statistics' on your class page. + + All the features of this dashboard are explained below. + - title: Level Selection + text: |- + + Firstly, you can select the levels you'd like to see on the dahsboard. Select the levels your students are currently working on by clicking on the number of that level. Deselect levels that you do not want to see by clicking them again. + In this example level 1 and 2 are selected. You can click on refresh to refresh the dashboard and get the most current stats. + - title: Class Overview + text: |- + + In the class overview you can see which adventure your students are working on right now. You can see that one student is working on the 'Rock, Paper, Scissors' adventure in level 1, one is working on the 'Fortune Teller' in level 1 and one student is working on the 'Rock, Paper, Scissors' adventure in level 2. + If you'd like to know which of your students is working on the adventure, simply click the number and their accountnames will appear. + You can also see how many of your students have finished the quiz. In this case, one student finished the quiz in level 1. Again, you can click the 1 to see which of your students it is. + + You can also see one of the students is 'missing' from this overview. That's because he's working on an adventure in level 4, which is not selected. + - title: Student List + text: |- + + Here you can find a list of your students and you can see their individual progress. The blue ring shows you what your students are currently working on. + + It is important to notice that the blue dots means that a students 'attempted' the adventure. This means that they ran a code in this adventure and went on to the next adventure, so this does not automatically mean that they did a good job! + If you want to see how an individual student is getting along, you can click their name in this overview. This is what you see if you click on marleen_h3a for example: + + You see that Marleen is having some trouble programming. She tried to run a program that contains blanks multiple times, so she might not realize that she has to change the code examples before running them. + In this way this overview can give you a better understanding of what a student is struggling with. + - title: Common Errors + text: |- + + If you're not only interested in individual struggles of your students, but you'd like to know what the whole class seems to be doing wrong, you can use this oversight of common errors. + The most common error messages that your students are recieving will appear in this oversight for you, so you could give some more instructions to the whole class if needed. + By clicking the error, you can see which students are having trouble with this error. By clicking resolve, you'll remove this error from the list. + - title: Overview of programs per adventure + text: |- + + Another useful overview of all the programs your students made in a level can be found on your class page. Go to the class page and click 'Overview of programs per adventure'. Here you'll find this overview. + You could use this overview to check your students' work. If they have made a program in an adventure, an eye appears in your overview. Click the eye to view their work. Did you like it? Then you can check the box and a green tick will appear. + This way you create a nice overview for yourself of your students' results. +- title: Extra Hedy features + key: features + subsections: + - title: Make your own adventure + text: It is also possible for teachers to create your own adventure. This video shows you how to create your own adventure as a teacher + and add it to your class(es). + - title: Explore page + text: |- + On the explore page you can view the work of other Hedy users. You can try out their programs and use them as inspiration to create something cool yourself. + You can also add a program you've made to the explore page yourself by clicking 'Save and share code' in the coding screen or go to My Programs and click 'Share'. + Don't want to share your work anymore? Simply go to 'My Programs' and click 'Unshare'. + If you want more information about the explore page, check out this video. + - title: My achievements + text: |- + If you click on your username in the topright corner of your screen, you can go to My achievements.

Then check out the 'Programmers Mode' switch at the bottom of your coding screen. + Programmers mode allows you and your students to use a bigger coding screen. + - title: Cheat sheets + text: |- + In every level there is a button with this emoji 🤔. You and your students can find the "cheat sheets" there. On this cheat sheet, you can find all the commands that are usable in this level in their correct form. + So if you've forgotten how a command works, simply take a peek at the cheat sheet! + - title: Video + text: This video + shows you even more features of Hedy, like the cheatsheets and the keyword switcher. +- title: After Hedy + key: after + subsections: + - title: What to do after Hedy? + text: |- + Congratulations on reaching the end of Hedy! Your students have now learned how to create their own basic programs in the Python programming language. + Of course, you could keep programming in our Hedy compiler, but it might be more exciting for your students to transfer to a "real" Python interface. + Would you like to continue teaching Python? Then please visit the Python website to learn how to get started in another compiler. + + Now that your students have a basic knowledge of programming in general, you could also show them around in other textual programming languages. The language might change but the concepts do not, so Hedy will still give them a big advantage. +- title: Answers to the exercises + key: answers + intro: |- + The answers to all the exercises can be found on the public profile of the useraccount 'Hedy_answers'. We often encourage students to use their own creativity in their answers, so these answers are merely a guideline as to what a possible correct answer could look like. + + To go to the 'Hedy_answers' profile, please click here. +- title: Common mistakes + key: common_mistakes + intro: |- + You can learn from your mistakes, especially in coding! Making mistakes is unavoidable, and a great opportunity to learn, but for teachers, it can be a challenge to find the correct fix for a mistake!
