The URLLIB2 module and the regular expression module are used. The following direct code:

#!/usr/bin/env python
#通过urllib (2) Module downloads network content
Import Urllib,urllib2,gevent
#引入正则表达式模块, Time module
Import Re,time
From gevent Import Monkey

Monkey.patch_all ()

def geturllist (URL):
Print URL
s = Urllib2.urlopen (URL)
Text = ()
#正则匹配, match the picture in it
html = (R ' <ol.*</ol> ', text, re. S
URLs = Re.finditer (R ' <p></p> ', (), Re. I)
For I in URLs: (1). Strip () +str ("JPG")
Url_list.append (URL)
Return url_list

def download (down_url):
Name=str (Time.time ()) [: -3]+ "_" +re.sub ('. +?/', ', Down_url ')
Print Name
Urllib.urlretrieve (Down_url, "d:\\temp\\" +name)
