[网络协议]python网络tcp客户端、服务端小练习

直接换下ip就能运行

import socket

    # 2.绑定端口
    addr = ("x.x.x.x", 9999)
    tcp_server_socket.bind(addr)
    print("绑定成功自身的ip与port")

    # 3.监听链接
    tcp_server_socket.listen(128)

    # 4.接收别人的连接
    # client_socket用来为这个客户端服务
    client_socket, client_addr = tcp_server_socket.accept()

    print("接收到的数据：%s" % recv_data)

    # 6.给对方发送数据
    client_socket.send("hahaha".encode("utf-8"))

    # 7.关闭套接字
    client_socket.close()
