python实现根据主机名字获得所有ip地址的方法

# -*- coding: utf-8 -*-
import sys, socket
result = socket.getaddrinfo('www.google.com', None, 0, socket.SOCK_STREAM)
counter = 0
for item in result:
  print "%-2d: %s" % (counter, item[4])
  counter += 1

运行结果：

0 : ('74.125.128.106', 0)
1 : ('74.125.128.147', 0)
2 : ('74.125.128.99', 0)
3 : ('74.125.128.103', 0)
4 : ('74.125.128.104', 0)
5 : ('74.125.128.105', 0)

希望本文所述对大家的Python程序设计有所帮助。
