Python’s socket module provides an interface to the Berkeley sockets API. This is the module that you’ll use in this tutorial. The primary socket API functions and methods in this module are: socket() .bind() .listen() .accept() .connect() .connect_ex() .send() .recv() .close(...
except binding. The main difference between server and client program is, in server program, it needs to bind host address and port address together. See the below python socket client example code, the comment will help you to understand the code. ...

1）你先启动server，看是否可以正常启动。2）因为是基于TCP的，所以你试试telnet可否链接到server上，格式为 telnet 127.0.0.1 5007 如果telnet没有找到的话，就配置下启动telnet。3） 如果telnet没有成功的话，则看下是否允许python访问网络，在控制面板里配置下，如果不是要允许访问。4）最后，服务...
