bug - import random

The error message says task 1 - import random - no longer works but its clearly at the top of the code.

Is this a bug?

also, pointers would be appreciated on the next steps... why isn't this working?

even.py
import random

start = 5

while (start>0):
    randnum = random.randint(1, 99)
    oddeven = even_odd(randnum)
    print ("{} is {}".format(randnum,oddeven))
    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.
    if num % 2 == 0:
        return even
    else:
        return odd

The message may be a bit misleading.

But it's because you've introduced a few errors in the program:

  • you reference even_odd before it is defined
  • inside even_odd you reference even and odd, and neither have been defined.

You could fix these and pass the challenge, but I don't think the challenge actually intended for you to modify the even_odd function. For task 3, you should write new code that makes use of the even_odd function as it was originally provided to satisfy the requirements.
