хорошо, проблема в том, что я продолжаю получать ошибку атрибута, которая говорит о том, что у моего Rect объекта нет атрибута rect, но я понятия не имею, почему это происходит? Я пытаюсь нарисовать прямоугольник (который должен быть веслом) по обе стороны окна для игры под названием понг, поэтому мне нужно включить прямоугольники в качестве класса для целей обнаружения столкновений, и в конце концов я хочу заставить весла двигаться. Я прочитал документацию и до сих пор не понимаю, почему это не работает
