Anaconda Distribution

Anaconda Distribution

There is a way to install and use Python that is different to the ¨normal¨one, Anaconda Distribution.

Anaconda works great when you are doing Data Analysis and Machine Learning, and not ¨normal¨ Python development. In our case we won´t use it because it requires for us to buy licenses if we are going to use it in a big company.

In any case is a great option, worth exploring for learning and small projects, or paying in the case of commercial use.

Web Page

Check if Python is already installed

Open a Terminal (or Command) window.

Type python3 --version.

We expect the result to be Python 3.8 or more. Currently the latest version (2022-07-13) is 3.10.5.

If we don't have Python installed it shows like this:

If we have Python installed it shows like this:

If it is not installed it shows like this:

If we already have Python Installed we are good to go

Python Installation

The process is different for each Operating System.

The easy way

Install from the Python Webpage

MacOS installation using Homebrew

brew install python3

Linux

sudo apt install python3

OR

sudo yum install python3

Create a Virtual Environment

• Confirm Python is installed running python3 --version in a terminal or console.
• Create a directory for the Bootcamp.
• Move to the new directory.
• Create the virtual environment with: python3 -m venv venv

The command reads as follows: python3 --- Use the Python 3 interpreter -m venv --- Use a module named venv > venv -- Create the new Virtual Environment in the venv directory

• Activate the virtual environment
  • In MacOS and Linux run source venv/bin/activate
  • In Windows run .\env\Scripts\activate

• Confirm you are using the virtual environment
  • In MacOS and Linux run which python
  • In Windows run where python
