问我如何阅读“印度时报”的标题并将其放入文本文件？

EN

import urllib2
import re
pat = re.compile('target="_parent">(.*?)</a>')

url = 'http://timesofindia.indiatimes.com/home/headlines'
sock = urllib2.urlopen(url)
li = pat.findall(sock.read())
sock.close()

print li

f=open("headlines.txt", 'a+')
for i in range(len(li)):
    f.write(li[i]+"\n")
f.close()

Error:Traceback (most recent call last):
