Python3 writing c/S Network program Example tutorial

This paper describes the implementation method of C/S network program written by Python3. Here's how:

The example described in this article is a C/s applet written according to Wingide, the specific code is as follows:

The client side myclient.py code is as follows:

#!/bin/env python#-*-coding:gb18030-*-#import socket import timei=1while i<10:  address= ("127.0.0.1", 3138)  S=socket.socket (socket.af_inet, socket. SOCK_STREAM)  s.connect (address)  buf= ' n:%d '% i  s.send (Buf.encode ()) #注意, In python3.0, the network send must be in byte string format, such as S.send (b "ABC") Buff=s.recv (())  if (len):    print (buff)   S.close  time.sleep (1)  i+=1

The server-side myserver.py code is as follows:

#!/bin/env python#-*-coding:gb18030-*-#import socketaddress= (' 127.0.0.1 ', 3138) s=socket.socket (Socket.af_inet, Socket. SOCK_STREAM) S.bind (address) S.listen (Ten) while True:  cfd,address=s.accept ()  buf=cfd.recv (1024x768)  Print (buf,address)  cfd.send (BUF)  cfd.close ()

It is hoped that the example of this paper will have some reference for Python network program design.
