Need help with the quiz "even_odd"

Hey guys,

Can someone check my code and tell what I'm doing wrong?

even.py 
import random
start = 5

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

Hi, Alexander Antoshin !

Well here is the solution. 

import random  # Import random library
start = 5  # Create start variable

def even_odd(num): 
    return not num % 2  # This returns True for even and False for odd

while start:
    num = random.randint(1, 99)  # You must only run random.randint(1, 99) ONCE. Because each time it woulod return a new random.
    if even_odd(num):  # You check num.
        print("{} is even".format(num)) # Print this if function returns True
    else:
        print("{} is odd".format(num))  # Print this if function returns False
    start -= 1

Does it make any sense? If you need more help - just ask!

In general I got it but still have some questions:

  1. Am I right that while loop and even_odd function are in separate blocks?
  2. Can't understand why "return not % 2" returns True if even and False if odd.
