This example describes how Python uses regular expressions to capture web images. We will share this with you for your reference. The details are as follows:

#! /Usr/bin/pythonimport reimport urllib # obtain webpage information def getHtml (url): page = urllib. urlopen (url) html = page. read () return htmldef getImg (html): # match the image 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 = 360 tpdq ") print getImg (html)
