Answer: Turtle Challenge #331

Here’s what the code from Turtle Challenge #331 draws. This picture was made by running the code for real.

The answers

How many points will the star have? 24 points. The turtle draws 24 lines and makes a sharp point at every turn.

How far does the turtle turn altogether? 24 × 105 = 2520 degrees. That’s 7 whole turns, so the star closes up neatly.

How the code works

Turning by a big angle like 105 degrees makes the turtle cross back over its own lines, which makes a star instead of a plain shape. Because 24 × 105 is an exact number of full turns (7), the turtle ends up back at the start.

import turtle

t = turtle.Turtle()
t.speed(0)
t.pensize(3)
t.pencolor("dodgerblue")

for point in range(24):
    t.forward(180)
    t.left(105)

t.hideturtle()
turtle.done()
