Python chat room implementation method based on in-process communication

This article describes how to implement a python chat room based on in-process communication. Share it with you for your reference. The details are as follows:

#!/usr/bin/env python# Added by <ctang@redhat.com>import sysimport osfrom multiprocessing import connectionADDR = ('', 9997)AUTH_KEY = '12345'class Server(object):  def __init__(self, username):    self.auth_key = AUTH_KEY    self.addr = ADDR    self.username = username    self.listener = connection.Listener(self.addr, authkey=self.auth_key)  def listen(self):    while True:      conn = self.listener.accept()      while True:        try:          request = conn.recv()          response = self.response(request)          conn.send(response)        except EOFError:          break      conn.close()  def reply(self):    message = raw_input("%s: " % self.username)    return message  def output_request(self, request):    sys.stdout.write('%s says: %s\n' % request)  def response(self, request):    self.output_request(request)    response = (self.username, self.reply())    return responseclass Client(object):  def __init__(self, username):    self.auth_key = AUTH_KEY    self.addr = ADDR    self.username = username    self.display_name = self.make_display_name(username)  def make_display_name(self, username):    return "%s: " % username  def connect(self):    self.conn = connection.Client(self.addr, authkey=self.auth_key)    while True:      message = raw_input(self.display_name)      self.send(message)      response = self.conn.recv()      self.output_response(response)   def send(self, message):    self.conn.send((self.username, message))  def output_response(self, response):    sys.stdout.write('%s says: %s\n' % response)def main():  mode = sys.argv[1]  if mode == 'server':    username = raw_input("Your name please: ")    server = Server(username)    server.listen()  elif mode == 'client':    username = raw_input("Your name please: ")    client = Client(username)    client.connect()if __name__ == '__main__':  main()
