I don't understand why my code doesn't work, I've already checked the syntax many times.

It could be a problem of the system, when try to check my work the system says: Oops! it looks like Task1.....

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

Syntax is OK, but logic is not. :)

You have infinite loop, because you increase start

There are two problems with your code.

First... You have to repeat the loop until "start" is falsey, so you have to decrement it's value, not increment. You should put:

start -= 1

at the end of your loop.

And the second one is actually a little harder to find, if you don't try to run this code on your own and use only the challenge page. Inside your loop, you call "even_odd" function but the definition of this function is after the loop itself, so your program simply doesn't know this function. You have to move the declaration of your function to the beginning of the program (but after import random).
