In workspaces the code returned the correct strings in a tuple. The grader says incorrect strings.

Is it an error in the syntax?

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

You're close, but there is no string method named "capitalize".

The string method that produces title case is named "title".

Looks like instead of the capitalize() function, they want the title() function.

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