Tell us what’s happening:

I am stranded again, someone please assist me with this

Your code so far


# User Editable Region

alphabet = 'abcdefghijklmnopqrstuvwxyz'
shift = 5
shifted_alphabet = alphabet[shift:] + alphabet[:shift]
translation_table = str.maketrans(alphabet, shifted_alphabet)
text = 'hello world'
encrypted_text = text.translate(translation_table)
print(encrypted_text)
def caesar(encrypted_text):
    alphabet = 'abcdefghijklmnopqrstuvwxyz'
    shift = 5
    shifted_alphabet = alphabet[shift:] + alphabet[:shift]
    translation_table = str.maketrans(alphabet, shifted_alphabet)

2

Put all your existing code within the function body.

This should be interpreted as move or cut and paste. You should not end up with duplicate lines of code.

3

Can shed more light on this statement: “You should not end up with duplicate lines of code.”

4

You have lines of code that are the same outside and inside your function

alphabet is defined twice.
shift is definied twice.


alphabet = 'abcdefghijklmnopqrstuvwxyz'    # duplicate
shift = 5
shifted_alphabet = alphabet[shift:] + alphabet[:shift]
translation_table = str.maketrans(alphabet, shifted_alphabet)
text = 'hello world'
encrypted_text = text.translate(translation_table)
print(encrypted_text)
def caesar(encrypted_text):
    alphabet = 'abcdefghijklmnopqrstuvwxyz'    # duplicate
    shift = 5                                      
    shifted_alphabet = alphabet[shift:] + alphabet[:shift]
    translation_table = str.maketrans(alphabet, shifted_alphabet)
5

still the same

Put all your existing code within the function body.

Don’t modify any lines.
alphabet isn’t a valid line of code.

Move all your existing code within the function body.

Really just put “def caesar” at the top and indent the rest.

existing code

To make that code a function:

def function():
    existing code

Thanks, really grateful
