a tuple of lowered, uppered, titlecased, and reversed string

Hi. my code doesnt seem like working in this century. I need some help please.

def split(string): string_list = string.split() return string_list

def uppercased(string_split): uppered = string_split.upper() return uppered

def lowercased(string_split): lower = string_split.lower() return lower

def titlecased(string_split): titlecased = string_list.title() return titlecased

def reverse(string_split): reverse = string_split[::-1] return reverse

def stringcases(string): a = uppercased() b = lowercased() c = titlecased() d = reverse() tuple(a, b, c, d) return (a, b, c, d)

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?
def split(string):
  string_list = string.split()
  return string_list

def uppercased(string_split):
  uppered = string_split.upper()
  return uppered

def lowercased(string_split):
  lower = string_split.lower()
  return lower

def titlecased(string_split):
  titlecased = string_list.title()
  return titlecased

def reverse(string_split):
  reverse = string_split[::-1]
  return reverse

def stringcases(string):
  a = uppercased()
  b = lowercased()
  c = titlecased()
  d = reverse()
  tuple(a, b, c, d)
  return (a, b, c, d)

You're not passing the string to a,b,c,d

def split(string):
  string_list = string.split()
  return string_list

def uppercased(string_split):
  uppered = string_split.upper()
  return uppered

def lowercased(string_split):
  lower = string_split.lower()
  return lower

def titlecased(string_split):
  titlecased = string_list.title()
  return titlecased

def reverse(string_split):
  reverse = string_split[::-1]
  return reverse

def stringcases(string):
  a = uppercased(string)
  b = lowercased(string)
  c = titlecased(string)
  d = reverse(string)
  return (a, b, c, d)

You don't need the parenthesis at the last return, but I would agree with the answer

In addition to not passing the string argument to the function calls in stringcases(), as mentioned by Emily, there is a syntax error in titlecased().

Traceback (most recent call last):
  File "<string>", line 32, in <module>
  File "<string>", line 28, in stringcases
  File "<string>", line 14, in titlecased
NameError: global name 'string_list' is not defined

"string_list" should be replaced with the defined parameter "string_split"

def titlecased(string_split):
  titlecased = string_split.title()  # <-- fixed
  return titlecased
