Python is an example of a method that USES regular expressions to grab web images

This article illustrates how Python USES regular expressions to grab web images. I will share it with you for your reference as follows:

#!/usr/bin/python
import re
import urllib
# Access to web information 
def getHtml(url):
  page = urllib.urlopen(url)
  html = page.read()
  return html
def getImg(html):
# Match the image in the page 
 reg = r'src="(.*?\.jpg)" alt'
  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://photo.bitauto.com/?WT.mc_id=360tpdq")
print getImg(html)

PS: here are two more handy regular expression tools for you to use:
