Okay, so Python isn't my strongest language, but there are a couple of issues I'm seeing.

def stringcases(some_string): # Yup, looks good.
    new_string = enumerate(some_string) # Why are you enumerating here?
    # enumerate() here would just return each index and character of the string.
    return new_string.uppercase() # The syntax here would just be upper(), no case.

Additionally, they are asking for all of the different cases detailed - not just one. So you'll need to return a tuple of all of the different modified strings: upper, lower, title, and reversed.

So, think of it as something like...

def stringcases(some_string):
    # 1. Create an all uppercase version of the string - syntax upper()
    # 2. Create an all lowercase version of the string - syntax lower()
    # 3. Create a titlecase version of the string, each word should be capitalized - syntax title()
    # 4. Create a reversed version of the string. This does not have a function, you will need to build it.
    #    Hint: There are several ways to do this. Maybe try using .join and reversed()?
    # 5. Return a tuple of all of the above. Tuples are immutable objects - syntax example = (1, 2, 3)

Try using the pseudo-code above to complete the challenge. If you're still having trouble, let me know and we can walk through a solution. Happy coding!
