#!/usr/bin/env python#coding:utf-8#filename:makefile demoimport Socketimport sysport = 70host = Sys.argv[1]filename = Sy S.argv[2]s = Socket.socket (socket.af_inet, socket. SOCK_STREAM) fd = S.makefile (' rw ', 0) fd.write (filename + ' \ r \ n ') for line in Fd.readlines (): Sys.stdout.write (line)
