本文實例講述了python實現TCP服務器端與客戶端的方法。分享給大家供大家參考。具體如下：
TCP服務器程序（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客戶端程序（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()運行說明：先運行服務器程序，作用類似于打開服務器保持等待客戶請求，再運行客戶端程序。
運行界面如下：
服務器端：
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...客戶端：
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>
希望本文所述對大家的Python程序設計有所幫助。
