Python: tcp and udp network programming example of SocketServer

Example of a tcp network program written using the SocketServer module (socketserver in python3:

 

#! /Usr/bin/env python

# Server

From SocketServer import TCPServer as TCP, StreamRequestHandler as SRH

Class MyRequestHandler (SRH ):
Def handle (self ):
Print I am server and recved: % s from % s % (self. rfile. readline (). strip (), self. client_address)
Self. wfile. write (I am server)

TcpServ = TCP (HOST, PORT), MyRequestHandler)
TcpServ. serve_forever ()

While True:
TcpCliSock = socket (AF_INET, SOCK_STREAM)
TcpCliSock. connect (HOST, PORT ))
TcpCliSock. send (I am client)
Data = tcpCliSock. recv (BUFSIZE)
If not data:
Break
Print I am client and recved:, data
TcpCliSock. close ()

Example of a udp network program programmed using the SocketServer module:

 

#! /Usr/bin/env python

# Server

From SocketServer import into ramrequesthandler as DRH, UDPServer as UDP

Class MyRequestHandler (DRH ):
Def handle (self ):
Print I am server and recved: % s from % s % (self. rfile. readline (), self. client_address)
Self. wfile. write (I am server)
Ss = UDP ('localhost', 6543), MyRequestHandler)
Ss. serve_forever ()
