what is wrong with this code, when I run it I see it gives what is expected.

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

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

Perhaps your testing was not quite what the verifier might use. It would be easy to miss the issue if you were only using a single word to test. Try using a string that contains several words.

you should use s.title() for the titlecased version instead of s.capitalize() because s.capitalize() would do the following:

lets say the string is "hello my name is Peter"

with s.capitalize() you are changing that string to: "Hello my name is Peter"

and with s.title() it would change to the form that the want the string: "Hello My Name Is Peter

I hope i could help you
