tuple test

why is my code marked as wrong why i type in workspace, but works fine in IDLE or Athom.

I can't seem to see my mistake.

stringcases.py 
def stringcases(arg):
    lower_arg = tuple((arg.lower()).split())
    upper_arg = tuple((arg.upper()).split())
    title_arg = tuple((arg.title()).split())
    reverse_arg = (arg.split())[::-1]

The function is supposed to return a tuple of string values. Your function doesn't return anything.

aa... of course. Instead of 'return' I was using print() XD

stringcases.py 
def stringcases(word):
    return word.upper(), word.lower(), word.capitalize(), word[::-1]

why is that marked as wrong?
