How to fix the code?

import random
def even_odd():
    start = 5
    while start > 0: 
        num = random.randint(1, 99) 
        if num % 2 == 0: 
            print("{} is even".format(num))
        else: 
            print("{} is odd".format(num))
        start-= 1
    # If % 2 is 0, the number is even.
    # Since 0 is falsey, we have to invert it with not.
    return not num %2


even_odd()

I have corrected this code as per my knowledge and it works well.

There were the following problems with your code:

• The defined function wasn't called in the main body of your code.
• 'start' variable had to defined in the function or should have been fed to the function using a parameter. I used the former.
• The parameter (random.randint(1, 99)) could have been fed to the function but i preferred to make the function such that it didn't require any parameters to initiate.

Hope this helps.

Hi Madeline

Here are the major points of the challenge:

1. Do not modify the even_odd function. The function is already written for you and you are not asked to change it in any way. What you are asked to do, though, is use it to determine whether a number is even or odd. The function is already set up to do that. It returns True if the number is even, and False if it is odd.
2. The while loop in task 3 needs to be outside of even_odd. In this while loop, you will call even_odd in order to check if a number is even or odd. The logic that you have in the loop is definitely on the right track, but you will need to use even_odd in the if condition, instead of "num % 2 == 0".

While Hassaan's code does pass the challenge, I think it is important to point out that it does not actually meet the specific requirements of what the challenge was asking. There is a big difference between modifying a function and modifying the code that calls the function, even if the results seem to be the same for a specific situation.

I only bring this up because correctly determining the constraints of a problem can be just as important as arriving at a solution. In practice, functions can be used many times over throughout a project and if you happen to modify one that you shouldn't, it could cause a lot of problems in other areas of the code.

The code for this challenge should end up taking the following format:

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:
    # write your code here

Hope this helps.
