function to lower upper reverse and titlecase the string into a tuple

Hi. I cant figure out what part of my code is going wrong. Here it comes:

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?

string = "python quizes are fine" string_list = [] def split(string): string_list = string.split() return string_list

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

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

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

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

def stringcases(string):

a = uppercased(string_list) b = lowercased(string_list) c = titlecased(string_list) d = reverse(string_list) target = tuple(a, b, c, d) return target

string = "python quizes are fine"
string_list = []
def split(string):
  string_list = string.split()

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

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

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

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

def stringcases(string):

  a = uppercased(string_list)
  b = lowercased(string_list)
  c = titlecased(string_list)
  d = reverse(string_list)
  target = tuple(a, b, c, d)
  return target

There are two errors in stringcases(). The statements should use the passed parameter string instead of string_list. Also, tuple() takes 1 argument, but 4 are given. You can create the tuple without the function:

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

def  Stringcases(astring):
    return astring.upper(), astring.lower(), astring.title(), astring[::-1]
