Tell us what’s happening:

i have been stuck on this question since long. Help

Your code so far


# User Editable Region

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()
    )

    return text.translate(translation_table)


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


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


encrypted_text = encrypt('Pbhentr vf sbhaq va hayvxryl cynprf.', 13)
print(decrypted_text)

Build a Caesar Cipher - Step 25

2

Replace the value assigned to encrypted_text with the following string, which represents a message to decrypt: Pbhentr vf sbhaq va hayvxryl cynprf..

Assign ONLY the string. o not assign a function call. That string is already encrypted.

Next: Do you see an error in the console?

3

code removed by moderator shld be in this format.

since we already created a function for encrypt and decrypt we are going to just assign the text to it.

hi @enigma9

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
