I don't know what is wrong here ???

def stringcases(arg):
    uppers = arg.upper()
    lowers = arg.lower()
    caps = arg.capitalize()
    reverse = arg[::-1]
    return upper, lower, caps, reverse

Hello! You are doing splendid! :clap: But there are a few very minor mistakes.

  • Why are you are defining uppers, then returning upper?
  • Similarly with the variable lowers.
  • The function to "Titlecase" isn't .capitalize(). It's .title().

.capitalize() only capitalizes the very first character, but .title() capitalizes the first letter of every word in the string. The problem expects you to use .title().

Other than those, your code is perfect! :+1:

Happy coding! :zap: ~Alex
