Googletranslate Python gadgets

I think Google online translation is quite useful. If I want to write a small tool, I can use it locally. I found two tools on the Internet that are not very useful (using python to call Google translation; using Google translation for Python ),

Now I have pasted my own code and used a regular expression to extract the translation content:

 1 # -*- coding:utf-8 -*-
 2  import urllib, urllib2
 3  import re
 4 import locale
 5 
 6 def getTranslateHtml(text):
 7     values = {'hl':'zh-CN', 'ie':'utf8', 'text':text, 'langpair':"en|zh-CN"}
 8     url = 'http://translate.google.cn/translate_t'
 9     data = urllib.urlencode(values)
10     req = urllib2.Request(url, data)
11     req.add_header('User-Agent', "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727)")
12     reponse = urllib2.urlopen(req)
13     return reponse.read()
14 
15 def getTranslateText(html):
16     rettxt = ''
17     m = re.search('<span id=result_box.*?><span .*?>.*?</span></span>', html)
18     if m is not None:
19         rettxt = re.sub('</?span.*?>', '', m.group(0))
20     return rettxt.decode('utf8').encode(locale.getpreferredencoding())
21 
22 if __name__ == '__main__':
23 
24     while True:
25         text = raw_input('Enter translate text(q exit):')
26         if text == 'q':
27             break
28 
29         print getTranslateText(getTranslateHtml(text))

The program running effect is as follows:
