A simple web server and client for python

server:

     Create a connection socket when the client contacts

     Receive HTTP requests from this connection (*)

     Interpret the specific file requested by the request 
     Get the file from the server's file system

     and send the file content

     If the file does not exist, return "404 Not Found" (*)

Client:

    The client can establish a TCP connection with the server

    The client requests a file on the server side through a TCP connection

    Display the content of the introduced file on the client

Note: Before running this file, the server.py directory needs to contain the file folder, which contains the files in the server, and the client can request the files in the file from the server.

readme: First open server.py, open the server         and then open         client.py , enter the         file
        name, including the suffix . py
