伺服器端：

# Echo server program  from socket import *  from time import ctime    HOST = ‘‘                 # Symbolic name meaning all available interfaces  PORT = 50007              # Arbitrary non-privileged port  BUFSIZE = 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(BUFSIZE).decode()          if not data:              break          tcpCliSock.send((‘[%s] %s‘ % (ctime(), data)).encode())      tcpCliSock.close()  tcpSerSock.close()  

　　用戶端：

# Echo client program  from socket import*    HOST = ‘127.0.0.1‘  PORT = 50007              # The same port as used by the server  BUFSIZE = 1024  ADDR = (HOST, PORT)    tcpCliSock = socket(AF_INET, SOCK_STREAM)  tcpCliSock.connect(ADDR)  while True:      data = input(‘> ‘)      if not data:          break      tcpCliSock.send(data.encode())      data = tcpCliSock.recv(BUFSIZE).decode()      if not data:          break      print(data)        tcpCliSock.close()
