Мне нужно знать, как я могу обновить текст метки, не создавая новое окно.У меня есть следующий код, но когда я пытаюсь изменить метку output_box на выходную переменную, определенную в import_csv(), я получаю ошибку 'function' object has no attribute 'output_box'.

Извините за избыточный код, но у меня действительно естьПонятия не имею, что является причиной проблемы.
