Python基于有道实现英汉字典功能

import re,urllib
aa="http://dict.youdao.com/search"
print ("input q! to exit ")
while 1:
  word=raw_input(">")
  if word=="q!":
    exit()
  else:
    word=word.replace(' ','+')
    url=aa+word
    s=urllib.urlopen(url).read()
    comm=re.compile(r'<td class="dttitle2"><font color="#013694"><b>(.*"attributem1web">(.*"no such word\n")
