Что я должен добавить здесь или где-либо еще в коде?

Итак, ваш код немного испорчен в начале, позвольте мне исправить это очень быстро, вы должны удалить неправильно размещенный («)

Теперь, когда это сделано, главный вопрос.

Вам нужно использовать циклы while, которые будут выполняться до тех пор, пока условие не станет ложным. В этом случае мы хотим, чтобы он повторялся до тех пор, пока пользователь не введет «нет». Поэтому вам нужно будет обернуть свой код while 1: Вот этим: (Плюс некоторые изменения, чтобы код работал)

This works perfect, if you need any help, post a comment!
