Problem with code from previous task (Task 1 is no loger working). I've not changed anything.

Hi,

I've a problem with Task 3, the code from previous task (Task 1 is no loger working?). I've not changed anything.

Is it possible it's the page or have I overlooked something.

Thanks & rgds, Jamie

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

Hey Jamie,

That error is a bit misleading. It always means that you have introduced a Syntax Error into the code Task you are currently working on, not a previous task.

Here, you introduced a Syntax Error when opening the while loop. You are using a single equal sign to try and compare a value. But a single equal sign assigns values, it does not compare. Here you need to use a double equal sign.

But to make things even DRYer, when you are checking for a boolean, you don't need to actually have any type of comparison. You could just have the statement like this:

while start:

This is the easiest way to say "While the variable start is truthy ...

Hope that helps. Keep Coding! :) :dizzy:
