客户端

 1 #客户端
 2 import socket
 3 
 4 client = socket.socket()#相当于声明socket类型，同时生成socket连接对象
 5 client.connect((‘localhost‘,6969))
 6 
 7 client.send(b"Hello World!")
 8 data = client.recv(1024)
 9 print("recv:",data)
10 
11 client.close()

服务端

 1 #服务器端
 2 import socket
 3 
 4 server = socket.socket()
 5 server.bind(("localhost",6969))#绑定要监听的端口
 6 server.listen()#监听
 7 
 8 print("我要开始等电话了")
 9 
10 conn,addr = server.accept()#等电话打进来
11 print(conn,addr)
12 
13 print("电话来了")
14 
15 data = conn.recv(1024)
16 print("recv:",data)
17 conn.send(data.upper())
18
