What is the complete code for even.py? I can't seem to get it right and I'm frustrated. Help.

Someone help.

even.py 
import random
start =  5

while start = False:
    num = random.randint(1, 99)
    if even_odd(num) != 0:
        print("{} is even").format(num)
    else:
        print("{} is odd").format(num)
    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

Hey there, being frustrated is part of the learning process. You were really close to the answer, just minor issues.

First thing to be done is to make sure that the while loop finishes executing when start isn't truthy anymore. Change your condition too:

while start:

You're print statements have a small issue. You have one of the closing brackets in the wrong places. Correct both of these and you have the answer.

print("{} is even".format(num))

Thanks, I also needed to move the fuction before the while loop. Other than that I really appreciate your quick and helpful reply!

Cheers!

Hi,

I used this code and it worked:

import random

start = 5

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

while start != 0: x = random.randint(1,99) y = even_odd(x) if y is True: print("{} is even".format(x)) else: print("{} is odd".format(x))

start = start - 1

Hope it helps
