Я занимаюсь разработкой простой текстовой игры Dungeon с использованием Python3. Сначала пользователю предлагается выбрать героя из файла screen.py.

Всякий раз, когда я запускаю этот код, я получаю эту ошибку: TypeError:в этом() принимает как минимум 2 аргумента (1 дано), что связано с Rogue () или другими классами героев. Вот's the hero.py.
