Python Python Collections (2016, retired 2019) Tuples Stringcases

returning tuple

I keep getting error messages, not sure what i'm doing wrong here

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

1 Answer

tuple is not an identifier. Try using single_string instead. Also, instead of tuple([::-1]), try single_string[::-1]
