Я создаю змею Pygame с меню, и я хорошо настраиваю ошибки и тому подобное, когда я сталкиваюсь с ошибкой
IndexError: список индекса выходит за пределы
ошибка действительно появляется после того, как я откройте вкладку и наведите на нее курсор
У меня есть слабое представление о том, что это на самом деле означает, но я совершенно новичок в python и кодировании в целом, поэтому я был бы признателен, если бы кто-то мог объяснить и показать решение,
большое спасибо и вот код
