#!/usr/bin/python# -*- coding: utf-8 -*-#encoding=utf-8#Filename:states_code.py import urllib2 url = '//www.jb51.net/'response = Nonetry:  response = urllib2.urlopen(url,timeout=5)except urllib2.URLError as e:  if hasattr(e, 'code'):    print 'Error code:',e.code  elif hasattr(e, 'reason'):    print 'Reason:',e.reasonfinally:  if response:    response.close()
