Socketserver

Before the ethical socket module is a single process, only one client connection and request can be accepted, and the connection and request from other clients can be accepted only after the client disconnects. Of course, we can also use the multi-threading module of Python to write a socket that can receive multiple client connections and requests at the same time. But this is not necessary, because the Python standard library has built a multi-threaded socket module Socketserver, we directly call on it, there is absolutely no need to repeat the wheel.

We simply need to retrofit the previous socket demo service side, the client does not change

See, is not very concise, in fact, Socketserver is a multi-threaded and class technology to the original socket module has been encapsulated, we use it is so simple
