can't pass this even odd challenge

I saved my code and ran it on my terminal, and it worked. But my code just wouldn't pass the challenge.

even.py 
import random

start = 5

def even_odd(num):
    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 -=1

This is the most ridiculous reason for a challenge not passing, but your answer is the periods that you have in your print sentences. Remove those and you should be good to go.

import random

def even_odd(num):
    return not num % 2

start = 5

while start:
    random_number = random.randint(1, 99)
    if even_odd(random_number):
        print("{} is even".format(random_number))  # No period
    else:
        print("{} is odd".format(random_number))  # No period
    start -= 1

HI Jingru Zhang

Basically, the only reason you cannot put periods is because of the specific answers the code checker is programmed to look for. Some (a very few) of the challenges would let it pass, but it really depends on the language and the type of return the checker is expecting..

So, it's not that your answer was incorrect, it just did satisfy the, often very picky, code checker. I look at it this way... more often than not, our own code needs to be very specific, so in a way, this help us to practice being very specific and helps us to develop a strong sense of the fine details. Honestly, I catch a lot more now than I did when I first started here. :smiley:

Keep Coding! :dizzy:
