Please help with even.py!

I think I have followed all the steps but for some reason it’s saying that task 1 is not passing. Task 1 was to import random. I would appreciate any help!

even.py 
import random

start = 5

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

while start:

    number = random.randint(1, 99)

    if even_odd(number):
        print("{} is even".format(number))
    else:
        print("{} is odd".format(number))

    start--

Hi Ollie,

It's objecting to start-- Try using start -= 1. Your code works fine with that.

Steve.

Thanks Steve! I didn't think of re-checking that minor bit of code.
