Python Network programming

1. Specific connection process I'm not going to say it. See also: http://woodpecker.org.cn/

2. Use the server-side and client-side communication examples to illustrate

3. On the Code

Service side (server.py)

1 #-*-coding:utf-8-*-2 ImportSocket3host="127.0.0.1"4port= 99995s =Socket.socket (Socket.af_inet,socket. SOCK_STREAM)6 S.bind ((host,port))7S.listen (1)8  while1:9Conn,addr=s.accept ()Tendata = CONN.RECV (1024) One     ifdata = ='Bye': A          Break -     Else: -         PrintData theTosend = Raw_input (">") - conn.send (tosend) -     ifTosend = ='Bye': -          Break +S.close ()

Client (client.py)

1 #-*-coding:utf-8-*-2 ImportSocket3s =Socket.socket (Socket.af_inet,socket. SOCK_STREAM)4Host ='127.0.0.1'  5Port = 99996 S.connect ((host,port))7  while1:8Tosend = Raw_input (">")9 s.send (tosend)Ten     ifTosend = ='Bye': One          Break Adata = S.RECV (1024) -     ifdata = ='Bye': -          Break the     Else: -         PrintData -S.close ()

4. When you run the test, first open the server side, and then you understand.
