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:codeex>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:codeex>python tsTclnt.py
