Any comma-separated list of things is a tuple, unless enclosed in something that explicitly creates another type (like brackets for a list, braces for a dictionary, etc.).

Hie, maybe you would want to first define your variable 'str' in the function before "return", then put everything in brackets before the commas. Example: str = (something.upper()), (something.lower())....

Then you "return" your variable...return str
