            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)

            final_message += alphabet[new_index]
    
    return final_message

#encrypted/decrypted
encryption = vigenere(text, custom_key, 1)
print(encryption)
decryption = vigenere(encryption, custom_key, -1)
print(decryption)

Hello Menonciro,

They meant you should update your existing comments to change encode in your first comment to encode/decode. And to change encrypted in your second comment to encrypted/decrypted.

This is because you changed the function to be able to do both now in stead of only encode and encrypt. So for clearance it asks you to change the comments to mention both.
