Python Python Collections (2016, retired 2019) Tuples Stringcases


Not sure what i'm doing wrong here , but i don't exactly where the problem is. Any idea please?

def stringcases(""):
    letters = 'treehouse'
    for letter,case in enumerate(letters.upper()):
    for letter,case in enumerate(letters.lower()):
    for letter,case in enumerate(letters.title()):
    for letter,case in enumerate(letters([::-1])):

     return letters

There seems to be a few issues, here are some hints:

  • the parameter name cannot be an empty string literal
  • you will need to work with the supplied argument instead of the word "treehouse"
  • you won't need any loops
  • you won't need to enumerate anything
  • the return value needs to be a tuple containing all 4 variations of the argument
  • the "return" line is indented one space too far
