这篇文章主要介绍了Python基础教程之tcp socket编程详解及简单实例的相关资料,需要的朋友可以参考下

初学脚本语言Python，测试可用的tcp通讯程序：

服务器：

									#!/usr/bin/env python 

									# -*- coding: utf-8 -*- 

									import socket 

									import threading 

									import time 

									def tcplink(sock, addr): 

									  print('Accept new connection from %s:%s...' % addr); 

									  sock.send(b'Welcome!!!'); 

									  while True: 

									    data = sock.recv(1024); 

									    time.sleep(1); 

									    if not data or data.decode('utf-8') == 'exit': 

									       break; 

									    sock.send(b'Hello, %s!' % data); 

									  sock.close(); 

									  print('Connection from %s:%s closed.' % addr); 

									if __name__ == "__main__": 

									  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM); 

									  s.bind(('127.0.0.1', 9090)); 

									  s.listen(8); #监听8个客户端； 

									  print('waiting for connection...'); 

									  while True: 

									    sock, addr = s.accept(); 

									    t = threading.Thread(target=tcplink, args=(sock,addr)); 

									    t.start();

客户端：

									#!/usr/bin/env python 

									# -*- coding: utf-8 -*- 

									import socket 

									s = socket.socket(socket.AF_INET, socket.SOCK_STREAM); 

									s.connect(('127.0.0.1', 9090)); 

									print(s.recv(1024).decode('utf-8')); 

									for data in [b'lk', b'aa', b'bb']: 

									  s.send(data); 

									  print(s.recv(1024).decode('utf-8')); 

									s.send(b'exit'); 

									s.close();
