Я пытаюсь написать обработчик / контроллер для сервера Minecraft. Моя проблема в том, что я не могу заставить писать и читать правильно работать. Когда клиент выполняет команду, которая использует метод класса сервера serverCom, текст / журнал сервера Minecraft начинает поступать в окно Python / консоль Python, и подключенный клиент зависает. Кроме того, кажется, что после того, как я использую Popen, сервер Minecraft не запускается, пока я не выполню запись на сервер (метод serverCom). Если кому-то интересно, Popen отправляется в пакетный файл, который открывает файл .jar. Это на Windows XP.
