Turtle Art Gallery

Every picture here was drawn by a short Python turtle program, using the same commands you learn in Python for Kids: forward, left, circle and loops. The pictures were made by running the code below for real.

The code for these pictures

Spiral galaxy

import turtle

t = turtle.Turtle()
t.speed(0)
t.pensize(2)
turtle.bgcolor("black")
colours = ["deeppink", "orange", "gold", "turquoise"]
for i in range(360):
    t.pencolor(colours[i % 4])
    t.forward(i * 1.5)
    t.left(59)

t.hideturtle()
turtle.done()

Rainbow flower

import turtle

t = turtle.Turtle()
t.speed(0)
t.pensize(2)

for i in range(36):
    t.pencolor(colours[i % 6])
    t.circle(120)
    t.left(10)
