利用Python快速查找爬取百度贴吧某页的全部图片

#coding=utf-8
import urllib
import re

def getHtml(url):
page = urllib.urlopen(url)
html = page.read()
return html

def getImg(html):
reg = r'src="(.+?\.jpg)" pic_ext'
imgre = re.compile(reg)
imglist = re.findall(imgre,html)
x = 0
for imgurl in imglist:
urllib.urlretrieve(imgurl,'%s.jpg' % x)
x+=1

html = getHtml("http://tieba.baidu.com/p/2460150866")

print getImg(html)


说明：Python版本2.7，更换网页地址可能要改写相应的正则表达式表示方法.
