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')
