使用Python从有道词典网页获取单词翻译

从有道词典网页获取某单词的中文解释。

import re
import urllib

word=raw_input('input a wordn')
 
url='http://dict.youdao.com/search?q=%s'%word
 
content=urllib.urlopen(url)
 
pattern=re.compile("</h2.*?</ul>",re.DOTALL)
 
result=pattern.search(content.read()).group()
pattern2=re.compile('<li>.*?</li>')
for i in pattern2.findall(result):
  print i.strip('<li>').strip('</li>').decode('utf-8')
