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 word\n')

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')
