Test post – Circle Spiral in Python

Using Turtle, learn how to create spiraling circles with different colours per circle.

Open IDLE and copy/paste the following code. Fell free to change the values and colours to see what happens.

import turtle
turtle.bgcolor("black")
turtle.speed(0)
colors = ["red", "yellow", "blue", "green"]
for x in range(360):
    turtle.pencolor( colors[ x % 4 ] )
    turtle.circle(x)
    turtle.left(90)
