This Python code generates a beautiful heart-shaped drawing using mathematical functions to define the curve shape.
Features:
- Creates smooth and elegant heart shapes.
- Utilizes mathematical functions for precise control over the curve.
- Allows for customization by adjusting parameters within the code.
Instructions:

turtle
library installed. - To install
turtle
, runpip install turtle
in your terminal.

Explanation:
The code leverages the turtle
library to draw shapes based on mathematical functions. Here's a breakdown of the key parts:
- Import: The
import math
line imports themath
library for mathematical calculations.- The
from turtle import*
line imports all functions from theturtle
library for convenience.
- The
- Heart Functions:
hearta(k) = 15*math.sin(k)**3
defines a mathematical function to calculate the x-coordinate of a point on the heart curve using sine and cube operations.heartb(k) = 12*math.cos(k)-5*math.cos(2*k)-2*math.cos(3*k)-math.cos(4*k)
defines a mathematical function to calculate the y-coordinate of a point on the heart curve using cosine and multiple angles.
- Turtle Setup:
speed(0)
sets the turtle's drawing speed to the fastest for a smoother animation.bgcolor("black")
sets the background color to black for a contrasting effect.
- Heart Drawing Loop:
- The
for i in range(6000)
loop iterates 6000 times, creating many small line segments to form the smooth heart shape. - Inside the loop:
goto(hearta(i)*20, heartb(i)*20)
uses the defined functions to calculate the coordinates and moves the turtle to that point on the curve, scaled by 20 for larger size.
- The
- Fill and Reset (Optional):
- The commented-out section (
for j in range(5): color("red"); goto(0,0)
) can be uncommented to fill the heart shape with red color using another loop and then reset the turtle's position for potential additional drawing. - Consider adjusting the number of iterations in the fill loop and the color as desired.
- The commented-out section (
- Hold the Window Open:
done()
keeps the turtle window open after drawing is complete, allowing you to view the finished artwork.
This combination of mathematical functions and turtle graphics creates a visually appealing and mathematically defined heart shape.
Customization:
- You can adjust the scaling factor (currently 20) in the
goto
calls to control the size of the heart. - Experiment with different mathematical functions in the
hearta
andheartb
definitions to create variations in the heart shape.
Have fun exploring and customizing the code!
