我正在为我的网络类工作，该网络类是一个客户端，与托管我们教授编写的基于文本的游戏的服务器进行交互。
我几乎所有事情都已经解决了，但我有一个主要问题，我不太了解python并且很难实现线程连续从服务器接收数据。
RuntimeError：主线程不在主循环中
这是我得到的错误，我相信这是因为tkinter必须始终在主线程中并且与我的接收函数冲突。我已经看到一个队列可能是这个问题的解决方案，但我无法理解如何在我的代码中实现这一点，任何帮助都将非常感谢。

答案 0 :(得分：1)
我很确定你遇到问题的原因是因为thread.join等待线程完成之后再做下一步。因此，在您的情况下，您实际上从未实际调用root.mainloop()。解决方案就是取出main中的thread.join行。
此外，在您的情况下，队列是必要的，因为您无法在另一个线程中更改Tkinter小部件。
如果没有太多的编辑，这就是您的代码的样子。
