Python Basics End challange

I can't get it right it says task one is no longer passing. It would be nice to have a proper example like the actual code so I can see what i'm doing wrong because right now i have no idea i've checked my indentations and all but luck's not on me today :P So please if anyone could give me an example that'd be very nice :D! (Already asked for help multiple times and I only got hints i'd like the actual code now please.)

1) For this challenge, we're going to need to use the random library. Add an import to the top of your file to bring it in.

2) Make a new variable, outside of the even_odd function, named start that's assigned to the number 5.

3) Make a while loop that runs until start is falsey. Inside the loop, use random.randint(1, 99) to get a random number between 1 and 99. If that random number is even (use even_odd to find out), print "{} is even", putting the random number in the hole. Otherwise, print "{} is odd", again using the random number. Finally, decrement start by 1.

Thanks in advance

even.py 
import random
start = 5


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

  else:

    print("{} is odd".format(num))
    start = 4






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

I removed the line after "even_odd" function and decreased start by 1, instead of setting it to 4 I was able to get this after the two changes:

# CODE STARTS HERE

import random
start = 5

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

# CODE ENDS HERE

Thanks for the answer but I still get the same error that task one is no longer passing I don't know what to do :/

For Python3, I had to move the even_odd function before using it, somehow my previous code works on Python2, I was using Python Shell and using the following command exec(open('C:/location_tomy_file/even.py').read())

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

Question, am I supposed to be seeing an 5 values returned? I just ran the code sample above and I got this

19 is odd
8 is even
36 is even
20 is even
23 is odd

Thanks.
