Python Python Collections (2016, retired 2019) Tuples Stringcases

Can anyone help me figure out whats wrong with my code to return uppercase, lowercase, titlecase, and reverse?

the method I have written works on my powershell not with the treehouse compiler. what I have to do is create a function that takes a string makes tuples of that string in uppercase, lowercase, titlecase and in reverse. Can't see what I've done wrong when my code works in powershell.

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

There is no need to convert each individual string into a tuple

def stringcases(a_string):
    upper = a_string.upper()
    lower = a_string.lower()
    title = a_string.title()
    reverse = a_string[::-1]
    return upper, lower, title, reverse

Otherwise your code looks good

thanks a lot appreciate the help

or you can do like this to make the code more pythonic:

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