Мне нужно открыть файл CSV. Прочитать его и, используя информацию из файла CSV, чтобы дать каждому ученику среднюю оценку (я сделал это уже в своем коде), когда я запускаю этот код, я получаю "2018-05-21 17: 53: 03.256 Python [15593: 2403648] Не удалось найти или прочитать файл строк. SlicesStrings "Я использовал много методов, но все еще получаю эту ошибку.

pls help ..
