Build a Caesar Cipher - Step 23

Python
1

Tell us what’s happening:

Step 23 of Caesar Cipher

def encrypt(text, shift):
return ‘caesar(text, shift)’
def decrypt(text, shift):
return ‘caesar(text, shift)’

I created the encrypt and decrypt functions just like how I created the caesar function. But it keeps saying that the encrypt function must return the caesar function? Am I reading this correctly? I also did a number of modifications and the one above is my latest attempt.

Your code so far

def caesar(text, shift, encrypt=True):

    if not isinstance(shift, int):
        return 'Shift must be an integer value.'

    if shift < 1 or shift > 25:
        return 'Shift must be an integer between 1 and 25.'

    alphabet = 'abcdefghijklmnopqrstuvwxyz'

    if not encrypt:
        shift = - shift
    
    shifted_alphabet = alphabet[shift:] + alphabet[:shift]
    translation_table = str.maketrans(alphabet + alphabet.upper(), shifted_alphabet + shifted_alphabet.upper())
    encrypted_text = text.translate(translation_table)
    return encrypted_text

encrypted_text = caesar('freeCodeCamp', 3)

Done! Sorry for the trouble. In one of my coding, I put encrypt=False in the decrypt function as an argument, it turns out it was not quite there. I tried so many mixes that everything got jumbled in my head.

Man, how do you solve it? I’m trying for hours.

def encrypt(text, shift):
    return caesar(text, shift)

def decrypt(text, shift):
    return caesar(text, shift, False)

Is that correct?
