Answer: Turtle Challenge #234

Here’s what the code from Turtle Challenge #234 draws. This picture was made by running the code for real.

The answers

How many circles will the turtle draw? 8 circles, one each time round the loop.

Why does the turtle turn 45 degrees after each circle? Because 8 × 45 = 360, so the circles spread evenly all the way round, like petals on a flower.

What colours will the circles be? They take turns: turquoise, darkorange.

How the code works

t.circle(40) draws a whole circle and brings the turtle back to the same spot. Turning a little between circles makes a flower pattern.

import turtle

t = turtle.Turtle()
t.speed(0)
t.pensize(2)
colours = ["turquoise", "darkorange"]

for petal in range(8):
    t.pencolor(colours[petal % 2])
    t.circle(40)
    t.left(45)

t.hideturtle()
turtle.done()
