stringToEncrypt = stringToEncrypt.lowerlower(), а присваиваешь переменной stringToEncrypt ссылку на него. Т.е. правильно будет: stringToEncrypt = stringToEncrypt.lower()stringToEncrypt = stringToEncrypt.lower вообще удалить, и сразу написать:stringToEncrypt = input("введи сообщение: ").lower()a словарь у тебя дважды повторяется? def caesar_cipher(string, shift, alphabet="abcdefghijklmnopqrstuvwxyz"):
