Python crawler for crawling web images

In the bar when you see the bar paste inside the beautiful picture, or have beautiful sister paper pictures, is not want to save it?

But some pages of pictures more, one by one to save more trouble.

Recently learning Python, so using Python to crawl the content of the Web is more convenient:

So I tried it for a bit.

------Code-------

#coding =utf-8import re   import urllib   //Import Module    def  gethtml (URL):    //Custom function to get Web page content    page=urllib.urlopen (URL)     html=page.read ()    return htmldef getimg (HTML):    //Custom Function, Get the content you need    reg=r ' src= ' (. +?\.jpg) " pic_ext '  //regular expressions, grab image links, see html.jpg    Imgre=re.compile (REG)            //compiles the regular expression into a regular expression object, To improve the crawl efficiency     imglist=re.findall (imgre,html)   //get all the matching regular expression objects in the HTML     x=1   for imgurl in imglist:           //loops through the entire list of links       urllib.urlretrieve (Imgurl, ' f:\\myimg\\ Myimage\\ %s.jpg '  % x)  //save picture to target folder       x=x+1       html=gethtml ("  //to get the page link  print getimg (HTML)-----------------------------------diagram: If you have any questions, please download the graphic image to view my Cheetah browser.
