    //server.py

    import socket
    import select
    import sys
    from thread import *

    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

        exit()

    IP_address = str(sys.argv[1])

    Port = int(sys.argv[2])

    server.bind((IP_address, Port))

    server.listen(100)

    list_of_clients = []

    def clientthread(conn, addr):

        conn.send("Welcome to this chatroom!")

        while True:

                        broadcast(message_to_send, conn)

                    else:

        list_of_clients.append(conn)

    conn.close()
    server.close()

客户端脚本将仅尝试访问在指定IP地址和端口上创建的服务器套接字。连接后，它将连续检查输入是来自服务器还是来自客户端，并相应地重定向输出。如果输入来自服务器，则它将在终端上显示该消息。如果输入来自用户，则它将用户输入的消息发送到服务器，以将其广播给其他用户。

    //client.py

    import socket
    import select
    import sys

    server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    if len(sys.argv) != 3:
        print "Correct usage: script, IP address, port number"
        exit()
    IP_address = str(sys.argv[1])
    Port = int(sys.argv[2])
    server.connect((IP_address, Port))

    while True:

        sockets_list = [sys.stdin, server]

        read_sockets,write_socket, error_socket = select.select(sockets_list,[],[])

        for socks in read_sockets:
            if socks == server:
                message = socks.recv(2048)
                print message
            else:
                message = sys.stdin.readline()
                server.send(message)
                sys.stdout.write("<You>")
                sys.stdout.write(message)
                sys.stdout.flush()
    server.close()
