1. 客户端和服务器聊天，可以一直聊天，直到一方发送’拜拜’。然后就可以和下一个人一直聊

import socket
def creat_server():
    server = socket.socket()
    server.bind(('10.7.153.122',8080))
    server.listen(512)
    while True:
        connect,addr = server.accept()
        while True:
            message = input('服务器:')
            connect.send(message.encode())
            if message == '拜拜':
                break

            recv_data = connect.recv(1024)
            print(str(recv_data, 'utf-8'))
            if recv_data == '拜拜':
                break

        connect.close()
creat_server()
import socket
def creat_client():
    client = socket.socket()
    client.connect(('10.7.153.122',8080))
    while True:
        data = client.recv(1024)
        receive_data = data.decode(encoding='utf-8')
        print(receive_data)
        if receive_data == '拜拜':
            break

        message = input("客户端:")
        client.send(message.encode())
        if message == '拜拜':
            break


    client.close()
