套接字通信Python与多线程&；多客户端到多服务器

我是Python套接字通信新手。我有一个关于多客户端和多线程的问题。我正在为服务器使用SocketTest3应用程序。我打开4个“SocketTest3”程序。它们都在本地主机上工作，但端口条目不同。后来，我创建的线程打开了我的客户机。到目前为止没有问题。但是我的客户端线程是按顺序打开的。问题就从这里开始。我希望这些线程同时启动。因为如果队列顶部的客户端无法连接到服务器，我的代码就会在其他客户端被允许连接之前爆炸。关于那个话题你能帮我吗？我的客户代码是

if __name__ == "__main__":
    runz = ClientSockets("localhost",8787,"localhost",8788,"localhost",8789,"localhost",8790)
    runz.run()

当我没有启动“8787”时，这是从Sockettest3程序连接的第一个端口，我的代码在启动之前停止工作

致以最诚挚的问候。

您是否尝试过将每个客户端连接包装到自己的try-except中？因为它们都是相同的，所以如果1失败，自然就不能得到2、3或4。@user3832673我将客户机连接从init移动到每个客户机方法中，问题就解决了。现在，即使第一个客户端的端口不活动，我也可以连接其他客户端。谢谢你的建议。
