How Can I fix my code?

I don't know what I did wrong

even.py 
import random
start = 5

while start:
  num = random.randint(1, 99)
  if even_odd(num):
    print("{} is even".format(num))
  else:
    print("{} is odd".format(num))
  start = start - 1

def even_odd(num):
    # If % 2 is 0, the number is even.
    # Since 0 is falsey, we have to invert it with not.
    return not num % 2

Hey Kevin, what is the error you are seeing? The only thing I can see is you might need to define your even_odd function before you use it in your while loop.

Cody's right. You need to put your loop after the function definition so you can call the function from inside your loop. Otherwise it looks good! :+1:
