 Mastering Python Turtle Graphics: Create Colorful Patterns with Code

Install command:

pip install PythonTurtle

import turtle

import colorsys

# Create a turtle object

t = turtle.Turtle()

# Create a screen object and set the background color

s = turtle.Screen()

s.bgcolor('black')

# Set the turtle's speed to the maximum

t.speed(0)

# Define the number of colors

n = 70

# Initialize the hue value

h = 0

# Loop for 360 degrees

for i in range(360):

    # Convert the hue value to an RGB color

    c = colorsys.hsv_to_rgb(h, 1, 1)

    # Increment the hue value

    h += 1 / n

    # Set the turtle's color to the generated color

    t.color(c)

    # Turn the turtle left by 1 degree

    t.left(1)

    # Move the turtle forward by 1 unit

    t.forward(1)

    # Loop to draw two circles

    for j in range(2):

        # Turn the turtle left by 2 degrees

        t.left(2)

        # Draw a circle with a radius of 100 units

        t.circle(100)

# Keep the turtle graphics window open

turtle.done()

Explanation:

• The bgcolor() method is called on the Screen object s instead of chaining it after the Screen() call.
• The bgcolor() method is passed the string 'black' to set the background color.
• The third parameter of the colorsys.hsv_to_rgb() function is removed because it is not required.
• The fd() method is changed to forward() to specify the distance the turtle should move forward. In this case, it's set to 1.
• The turtle.done() function is called at the end to keep the turtle graphics window open.
