Build a Caesar Cipher - Step 25

Python
1

Tell us what’s happening:

please help, i think have made it right, but it’s not working

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

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


# User Editable Region

encrypted_text = encrypt('Pbhentr vf sbhaq va hayvxryl cynprf.', 3)
print(encrypted_text)

decrypted_text = decrypt(encrypted_text, 13)
print(decrypted_text)

Hi @nokyardiyansyah,

encrypted_text = encrypt('freeCodeCamp', 3)

print(encrypted_text)

This was the starting code for this step.

You are asked to remove the assignment to the existing ecrypted_text variable and replace it with the string 'Pbhentr vf sbhaq va hayvxryl cynprf.'

Happy coding!

I’ve replaced it, but it still doesn’t work
