Build a Caesar Cipher - Step 22

Tell us what’s happening:

the code runs without error so I can’t see anything wrong here. when I press check your code it tells me “You should set shift to - shift when encrypt is not truthy.”

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'

# User Editable Region

    if not encrypt:
        set(shift = - shift)

# User Editable Region

    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)
print(encrypted_text)

You don’t need set() here.
