I don't understand why this works in workspace but the challenge tells me it is wrong

Please see my string cases code and help me understand why the challenge is saying it is the wrong output. It is supposed to return a tuple.

stringcases.py
# Handy functions:
# .upper() - uppercases a string
# .lower() - lowercases a string
# .title() - titlecases a string
# There is no function to reverse a string.
# Maybe you can do it with a slice?
my_string = "I am what I am"

def stringcases(my_string):
  a = my_string.upper()
  b = my_string.lower()
  c = my_string.title()
  my_list = my_string.split()
  my_list_reverse = my_list[len(my_string)::-1]
  d = " ".join(my_list_reverse)
  e = (a, b, c, d)
  return e

stringcases(my_string)

I think by "reverse a string" it's asking to the reverse it character by character, not word by word. Essentially "ma I tahw ma I", not "am I what am I".
