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)：
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 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客戶端程序(tsTclnt.py)：
?
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 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()運行說明：先運行服務器程序，作用類似於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：
