Python Python Basics (2015) Letter Game App Even or Odd Loop

Am I decrementing correctly in this python challenge?

The last step is to decrement start by 1, which I think I've done, but it's not passing, and I'm also unsure how start relates to num.

even.py 
import random

start = 5

def even_odd(num):
    while start = true:
        num = random.randint(1,99)
        if num % 2 == 0:
            print("{} is even".format(num))
        elif num % 2 != 0:
            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

Dan:

Actually, the decrement statement should be indented under the while loop. Also you need the proper equality operator (==) in your while loop.

while start == true:
    ....
    start -= 1

jonlunsford Thank you. I made those changes, and now I'm getting an error that says I have the wrong number of prints. I have two prints, both which are specified in the directions. 

import random

start = 5

def even_odd(num):
    while start == true:
        num = random.randint(1,99)
        if num % 2 == 0:
            print("{} is even".format(num))
        elif num % 2 != 0:
            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

true has to be spelled like this: True
