Python even.py challenge

So I did the code challenge as asked, but now I always get the "Bummer! Try again!" error message. When I try it out in my own code editor it seems to work fine. I don't know what to do about it.

even.py 
import random

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

start = 5
while start:
    number = random.randint(1, 99)
    if even_odd(number):
        print("{} is even.".format(number))
    else:
        print("{} is odd.".format(number))
    start -= 1

Your code is correct. The challenge is just very picky about exactly what gets printed. If you remove the periods from the end of your strings you will pass the challenge.
