复制代码 代码如下:

# -*- coding: utf-8 -*-

import re

import urllib

def getHtml(url):

#找出给出网页的源码

page = urllib.urlopen(url)

html = page.read()

return html

def getImg(html):

#正则

reg = r'src="(.*?.jpg)"'

#编译正则

imgre = re.compile(reg)

#找出图片地址

imglist = re.findall(imgre,html)

#循环遍历

x = 0

for i in imglist:

urllib.urlretrieve(i,'%s.jpg' % x)

x+=1

html = getHtml(r'http://www.renren.com/')

getImg(html)
