stringcases reversed string is working fine in workspaces

My stringcases code is working fine in workspaces but the code challenge is telling me that the function is returning the wrong value for the reversed case string.I can't seem to figure out where I am failing.

stringcases.py 
def stringcases(my_string):
    uppercase=my_string.upper()
    lower=my_string.lower()
    title=my_string.title()
    def reverse_case(a_string):
        reversed_case=''
        upper_alpha=('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z')
        for letter in a_string:
            if letter in upper_alpha:
                letter=letter.lower()
            else:
                letter=letter.upper()
            reversed_case+=letter
        return reversed_case


    return(uppercase,lower,title,reverse_case(my_string))

:warning: Be careful about testing a challenge in the workspace..

If you have misunderstood the challenge, it's also very likely that you will misinterpret the results.

In this case, you're reversing the letter case for the last variation. But what the challenge is asking for is a variation where the string itself is reversed. For example, if the string was "grab" then the 4th variation would be "barg".
