g'day парни,
У меня небольшая ошибка с моей программой, когда при попытке сохранить в файл возникает ошибка, которая говорит: «Требуемая привилегия не удерживается клиентом». Я не уверен, как это исправить, поскольку я запускаю его на своем ноутбуке, которым пользуюсь только я, и если я не настроил статус администратора правильно, я не знаю, что происходит.
Я разместил свой код ниже, чтобы быть уверенным
Приветствие.
