Answer: Turtle Challenge #328

Here’s what the code from Turtle Challenge #328 draws. This picture was made by running the code for real.

The answers

How many points will the star have? 36 points. The turtle draws 36 lines and makes a sharp point at every turn.

How far does the turtle turn altogether? 36 × 170 = 6120 degrees. That’s 17 whole turns, so the star closes up neatly.

How the code works

Turning by a big angle like 170 degrees makes the turtle cross back over its own lines, which makes a star instead of a plain shape. Because 36 × 170 is an exact number of full turns (17), the turtle ends up back at the start.

import turtle

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

for point in range(36):
    t.forward(150)
    t.left(170)

t.hideturtle()
turtle.done()
