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 ctime
HOST = ‘‘
PORT = 21567
BUFSIZ = 1024
ADDR = (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 = 21567
BUFSIZ = 1024
ADDR = (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 data1
tcpCliSock.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.py waiting 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。
