        else:        
            # Find the right key character to encode
            key_char = key[key_index % len(key)]
            key_index += 1

            # Define the offset and the encrypted letter
            offset = alphabet.index(key_char)
            index = alphabet.find(char)
            new_index = (index + offset) % len(alphabet)
            encrypted_text += alphabet[new_index]

Hello @remuschilom1489,
You have to add direction as the third parameter.

Instead of using comment above please use it in front of them!

Happy Coding :man_technologist:

You need to have 3 parameters defined for the vigenere function.

Can you share your full code again?
