tuple

So what's wrong with this code?

stringcases.py 
def stringcases(single_string):
    single_string.upper(),single_string.lower(),single_string.title(),single_string[::-1]

You aren't actually returning anything. Try returning the tuple you made.

def stringcases(single_string):
    return (single_string.upper(),
            single_string.lower(),
            single_string.title(),
            single_string[::-1])

(Note that I extended the tuple to multiple lines. This isn't required, but it looks nicer in my opinion.)
