本文实例讲述了python实现TCP服务器端与客户端的方法。分享给大家供大家参考。具体如下：

TCP服务器程序（tsTserv.py）：

from socket import *from time import ctimeHOST = ''PORT = 21567BUFSIZ = 1024ADDR = (HOST, PORT)tcpSerSock = socket(AF_INET, SOCK_STREAM)tcpSerSock.bind(ADDR)tcpSerSock.listen(5)while True:  print 'waiting for connection...'  tcpCliSock, addr = tcpSerSock.accept()  print '...connected from:', addr  while True:    data = tcpCliSock.recv(BUFSIZ)    if not data:      break    tcpCliSock.send('[%s] %s' %(ctime(), data))  tcpCliSock.close()tcpSerSock.close()

TCP客户端程序（tsTclnt.py）：

from socket import *HOST = 'localhost'PORT = 21567BUFSIZ = 1024ADDR = (HOST, PORT)tcpCliSock = socket(AF_INET, SOCK_STREAM)tcpCliSock.connect(ADDR)while True:  data = raw_input('> ')  if not data:    break  tcpCliSock.send(data)  data1 = tcpCliSock.recv(BUFSIZ)  if not data1:    break  print data1tcpCliSock.close()

运行说明：先运行服务器程序，作用类似于打开服务器保持等待客户请求，再运行客户端程序。

运行界面如下：

服务器端：

D:/code/ex>python tsTserv.pywaiting for connection......connected from: ('127.0.0.1', 2883)waiting for connection......connected from: ('127.0.0.1', 2885)waiting for connection......connected from: ('127.0.0.1', 2889)waiting for connection......connected from: ('127.0.0.1', 2891)waiting for connection......connected from: ('127.0.0.1', 2892)waiting for connection......connected from: ('127.0.0.1', 2893)waiting for connection...

客户端：

D:/code/ex>python tsTclnt.py> 1[Thu Feb 02 15:52:21 2012] 1> 2[Thu Feb 02 15:52:22 2012] 2> 3[Thu Feb 02 15:52:22 2012] 3> 5[Thu Feb 02 15:52:23 2012] 5> 6[Thu Feb 02 15:52:24 2012] 6>D:/code/ex>

希望本文所述对大家的Python程序设计有所帮助。
