even_odd function stuck

def even_odd(number): if number in even_odd % 2 == 0: return True break else: return False

I am stuck here, getting only 'bummer try again' to direct me towards the solution, I have tried many variations but I am not having any luck on identifying where I am stuck. I am confused on the use of the random replacements for the parameters as well, do I need to introduce a new obscure variable somewhere, or is this mostly correct? Do I use if number % 2 == 0, a form of this, or do I need to introduce new pieces?

even.py 
def even_odd(number):
  if number in even_odd % 2 == 0:
    return True
    break
  else:
    return False

Hey Mark,

There seems to be a couple of things here:

  1. The if statement should be checking to see if the (number % 2) is equal to zero. This should return a boolean. I'm not sure why you have include a in even_odd? I think you may be confusing an if statement with a for loop.

  2. With an if/else clause, you cannot use a break statement. If something fails the if, the break will prevent it from ever reaching the else ... so incorrect syntax.

Below is the corrected code for you reference. I hope it will make sense. :)

def even_odd(number):
  if (number % 2) == 0:
    return True
  else:
    return False

Now, the if statement is checking the formula against the number passed into the method. If the result is zero, it will return true and execute the return True. If the result is false, the code in the else clause will execute instead.

:dizzy:
