Even_Odd function will work in Workspaces, but not in the Challenge

I am writing a while loop that iterates for as long as the counter variable is True. The loop is supposed to get a random number between 1 and 99, then pass that number into a function that evaluates whether it is even or odd. Once the function finishes, an if statement is supposed to print out statements, saying whether the number is even or odd. I can get this code to work in my workspaces, but it is not acceptable to the code challenge. I don't know about this one, please help!! Thanks!

even.py 
import random
start = 5
def even_odd(num):
    # If % 2 is 0, the number is even.
    if num % 2 is 0:
    # Since 0 is falsey, we have to invert it with not.
        return not num % 2

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

The challenges are very picky about returned strings.

You apparently added some punctuation (periods) that was not asked for in the instructions. It looks nice, but it makes the challenge checker think the output is wrong.

Hey Steven,

Thanks for your comment, but could you be a bit more specific? I'm not seeing any extra periods, or punctuation that is unnecessary..

Here's one of them. The challenge asked for "{} is even" (with no period), but you wrote this:

        print("{} is even.".format(num))
#                        ^
#                        that's the period I'm talking about
