我希望客户端也可以从广播服务器套接字 python 发送私人消息

Question

我已经制作了一个广播服务器和客户端，我使用了一条消息作为命令，如@private 作为命令工作，它将列出所有用户，然后我希望它应该是 select 其中之一，然后它只能与聊天只有他选择并在后端广播的那些客户也为其他人工作

我已经为它调用了一个 function，它是chatwithtwo()但问题是当select_username变量正在接收值时其他线程也在同时工作，所有这些都搞砸了请帮助我解决这个问题

只需从线程 function 中删除for i in range(len(clients)): this 即可完成

每次客户端连接到服务器时，它都会运行您的线程，就像如果一个客户端已连接，那么它将运行 1 次 threads=1 running 然后第二次运行然后它的值将为 2 并且循环将运行两次并且线程值填充被添加到最后一个，就像现在正在运行的线程是 1，在循环 2 之后将添加更多线程，现在线程是 3，依此类推。
