Python---socketserver module

Serial processing of socket communication via the socket module in the "Python---socket module"

In Python, concurrent communication can be achieved through the Socketserver module, while the Socketserver can be implemented concurrently through IO multiplexing and multi-process, multithreading

The following is an example of using the Socketserver module for multithreading concurrent processing requests
