Bummer where's stringcases()?

Okay so I have this code here and I would like to know what I'm doing wrong

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 stringcases(string):
    string = "Fischer Fritz fischt frische fische"
    a = string.upper()
    b = string.lower()
    c = string.title()
    e = string[-1:-36:-1]
    f = a, b, c, d, e 
    return f

You are returning a variable named "d" inside that tuple that doesn't exist. And there's no need to create the string inside the function, you are receiving it as a parameter You could do it without all the variables:

# 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(str_value):

    return (str_value.upper(), str_value.lower(), str_value.title(), str_value[::-1]) 

I hope that helps a little bit

I received the same message initially after pasting my code from my ide pycharm, but was solved by typing the code manually into the Challenge.

"""python

def stringcases(my_string): new_string = my_string.upper(), my_string.lower(), my_string.title(), my_string[::-1] return new_string

"""

Markdown is not wanting to format, so remember to not just copy and paste this code - format /indent where required.
