Python实现群聊天小程序代码

群聊服务端

服务端Server.py代码如下：

        client.send(wel)
        name = client.recv(1024)
        inputs.append(client)
        fd_name[client] = name
        nameList = "已在线聊天的群成员是 %s" % (who_in_room(fd_name))
        client.send(nameList)

群聊客户端

客户端Client.py代码如下：

    return s

"""

def lis(s):
    my = [s]
    while True:
        r, w, e = select.select(my, [], [])
        if s in r:
            try:
                print s.recv(1024)
            except socket.error:
                print "通信出现异常"
                exit()

"""

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()

"""

"""
def main():
    ss = conn()
    t = threading.Thread(target=lis, args=(ss,))
    t.start()
    t1 = threading.Thread(target=talk, args=(ss,))
    t1.start()


if __name__ == '__main__':
    main() 

先启动服务端代码，后启动客户端（启动一个，代表一个群成员，可多个）代码，执行结果如下：
