最近在学爬虫，看了点视频学了点东西，写了一个百度贴吧的爬虫上来

目前只是把爬取网页信息，存储到本地

#-*- coding:utf-8 -*-# 识别中文注释 import urllib2def load_page(url):user_agent ="Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11"headers = {'User-Agent':user_agent}req = urllib2.Request(url,headers = headers)response = urllib2.urlopen(req)page = response.read()return  pagedef tieba_spider(url,beginPage,endPage):'''贴吧小爬虫'''for i in range(beginPage,endPage+1): myurl = url + str(50*(i-1))print "url :" + myurlhtml = load_page(myurl)file_name =str(i)+".html"writeFile(file_name,html)def writeFile(file_name,txt):f = open(file_name,'w')f.write(txt)f.close()if __name__ == "__main__":url = raw_input("please input the url :")beginPage = int(raw_input("begin : "))endPage = int(raw_input("end : "))tieba_spider(url,beginPage,endPage)

过几天有时间再学点正则表达式加进去
