客户端脚本将简单地尝试访问在指定 IP 地址和端口创建的服务器套接字。一旦连接，它将不断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，它会在终端上显示消息。如果输入来自用户，它将用户输入的消息发送到服务器，以便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()
