Question

我正在尝试实现此处编写的代码：

https://www.geeksforgeeks.org/simple-chat-room-using-python/

我可以使其正常运行，但找不到关闭连接的方法。该代码一直运行到我输入键盘中断为止。我想实现一个关键字，它将关闭客户端和服务器并释放端口。

我已经实现了客户端代码，以在消息“退出”时退出，但是相同的技术在服务器代码中不起作用。我一直被“ conn，addr = server.accept（）”这一行所吸引，并返回错误

Traceback (most recent call last):
  File "newServer.py", line 66, in <module>
    conn, addr = server.accept()
  File "/Users/######/anaconda3/lib/python3.7/socket.py", line 212, in accept
    fd, addr = self._accept()
ConnectionAbortedError: [Errno 53] Software caused connection abort

任何帮助将不胜感激！

编辑：添加代码
