python 爬虫入门1 爬取代理服务器网址

刚学，只会一点正则，还只能爬1页。。以后还会加入测试

 #coding:utf-8

 import urllib
 import urllib2
 import re

 #抓取代理服务器地址
 Key = 1
 url = 'http://www.xicidaili.com/nt/%s' %Key
 #print url

 user_agent='Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36'
 headers={'User-Agent' :user_agent}

 try:
     request = urllib2.Request(url,headers=headers)
     response=urllib2.urlopen(request)
     html=response.read()
     pattern=re.compile('<td class="country".*?<td>(\d+).(\d+).(\d+).(\d+)</td>.*?<td>(\d+)</td>',re.S)
     items=re.findall(pattern,html)
     for item in items:
     #    if item !='HTTP'or'HTTPS':
             print "%s.%s.%s.%s:%s" %(item[0],item[1],item[2],item[3],item[4])
 except urllib2.URLError,e:
     if hasattr(e,'code'):
         print e.code
     if hasattr(e,'reason'):
         print e.reason
