from TurtleWorld import *
import math

bob = Turtle()
print(bob)

draw_circle(turtle, r):
    d = r*2
    c = d*math.pi
    degrees = 360/25
    length = c // 25
    for i in range(25):
        fd(turtle, length)
        rt(turtle, degrees)

draw_circle(bob, 25)

wait_for_user()

The problem in on line 7:

draw_circle(turtle, r):

The compiler only tells me that there is a syntax error and highlights the colon at the end of that line. I'm sure I'm missing something simple, but the code looks right to me.

in python, we define functions using the def keyword.. like

You need to write:

def draw_circle(turtle, r):

to define a function.

Your missing the def part?

I thought, just in case the other three answers weren't obvious enough, I should tell you that you need def first

def draw_circle(turtle, r):

@People duplicating: Seriously, could we get 1 more answer? I believe 3 (4 if you add me) isn't enough
