Python Python Collections (Retired) Tuples Stringcases

stringcases.py function returning a tuple with case changes from a string input

Not sure what's wrong with code

# 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?

def stringcases(string):
  up = string.upper()
  lo = string.lower()
  tit = string.title()
  for itb in string:
    rev = itb[::-1]
  stringcases = (up, lo, tit, rev)
  return stringcases

To reverse the string you don't need the for loop. Just do: rev = string[::-1]

I could have sworn I tried that.. GRRRRrrrrrRRR! Haha

Thanks Kourosh!
