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.

import turtle
scrin = turtle.Screen()
t = turtle.Turtle()
for i in range(15): #draw 15 trapezoids, 24 degrees apart
