Answer: Turtle Challenge #129

Here’s what the code from Turtle Challenge #129 draws. This picture was made by running the code for real.

The answers

What will the line look like? A zigzag, like a lightning bolt or the edge of a crown. The turtle goes up, then down, again and again.

How many points will stick up? 8, one for each time round the loop.

How the code works

Each time round the loop the turtle turns right 60 degrees, draws, then turns left 60 degrees and draws again. Right then left, right then left: that’s a zigzag.

import turtle

t = turtle.Turtle()
t.speed(0)
t.pensize(6)
t.pencolor("forestgreen")
t.left(30)

for zig in range(8):
    t.forward(50)
    t.right(60)
    t.forward(50)
    t.left(60)

t.hideturtle()
turtle.done()
