Python implements group chat applet code

Group Chat Service Side

The service-side server.py code is as follows:

#-*-Coding:utf-8-*-#!/usr/bin/env python # @Time: 2018/5/18 16:05# @Desc: Group chat Server # @File: server.py# @Softwa Re:pycharmimport socket, selecthost = Socket.gethostname () port = 5999addr = (host, port) inputs = []fd_name = {} ' "" Traverse Group member " "" Def Who_in_room (w): Name_list = [] for k in W:name_list.append (W[k]) return name_list "" "Connection" "" Def Conn ( ): print "server start run" SS = Socket.socket () ss.bind (addr) Ss.listen (5) return SS "" "Add new Group member" "" Def new_coming (ss ): client, add = ss.accept () print ' Welcome%s%s '% (client, add) Wel = ' Welcome to the chat room.

Group chat Client

The client client.py code is as follows:

#-*-Coding:utf-8-*-#!/usr/bin/env python # @Time: 2018/5/18 16:06# @Desc: Group chat client # @File: client.py# @Softwa Re:pycharm import socket, select, Threadinghost = Socket.gethostname () addr = (host, 5999) "" "Connection" "Def Conn (): s = sock Et.socket () s.connect (addr) return S "" "Get Group Member" "Def Lis (s): my = [s] While True:r, W, E = Select.selec                T (my, [], []) if s in R:try:print s.recv (1024x768) except Socket.error: Print "Communication exception" exit () "" "Input chat" "Def Talk (s): While True:try:info = Raw_input (        ) except Exception, E:print ' can\ ' t input ' exit () Try:s.send (info) Except Exception, E:print e exit () "" "Main function, create chat and get group member thread" "" Def Main (): SS = conn () T = Threadi Ng. Thread (Target=lis, args= (SS,)) T.start () T1 = Threading. Thread (Target=talk, args= (SS,)) T1.start () if __name__ = = ' __main__ ': main()  

Start the server-side code, then start the client (start a, representing a group member, can be multiple) code, the execution results are as follows:
