Example of a method for Python to grab news headlines and links regularly

This article demonstrates an example of how Python can regularly grab news headlines and links. I will share it with you for your reference as follows:

#-*-coding:utf-8-*-
import re
from urllib import urlretrieve
from urllib import urlopen
# Access to web information 
doc = urlopen("http://www.itongji.cn/news/").read() # Of your own 1 Big data news website 
# Grab news headlines and links 
def extract_title(info):
  pat = '<h3><a target=\"_blank\"(.*?)</a></h3>'
  title = re.findall(pat, info)
  titles='\n'.join(title)
  #print titles
# Modify the specified string 
  titles1=titles.replace('class="title"','title')
  titles2=titles1.replace('>',':')
  titles3=titles2.replace('href','url:')
  titles4=titles3.replace('="/','"http://www.itongji.cn/')
# Written to the file 
  save=open('xinwen.txt','w')
  save.write(titles4)
  save.close()
titles = extract_title(doc)
