Скачать или смотреть Python Turtle Code: Rotating Trapezoid

A spirograph created by 15 trapezoids stamped as images of a rotating figure. The Python Turtle code uses a loop. The "normal" orientation of the turtle in this case is facing the first side of the last trapezoid drawn.

t.pensize(5)

for i in range(15): #draw 15 trapezoids, 24 degrees apart
t.color("blue")
t.forward(250)
t.left(120)
t.color("black")
t.forward(100)
t.left(60)
t.color("red")
t.forward(150)
t.left(60)
t.color("blue")
t.forward(100)
t.left(144) #new_trapezoid: rotate turtle 120 + 24 degrees
