问题

Here is the code:

# coding: utf-8
from googletrans import Translator
translator = Translator()
print translator.translate('here', dest='zh-CN')

everything goes well before today. But not I try to use this python library. then I got this error.

root@localhost:~# python googletest.py 
Traceback (most recent call last):
  File "googletest.py", line 4, in <module>
    print translator.translate(u'here', dest='zh-CN')
  File "/usr/local/lib/python2.7/dist-packages/googletrans/client.py", line 132, in translate
    data = self._translate(text, dest, src)
  File "/usr/local/lib/python2.7/dist-packages/googletrans/client.py", line 57, in _translate
    token = self.token_acquirer.do(text)
  File "/usr/local/lib/python2.7/dist-packages/googletrans/gtoken.py", line 180, in do
    self._update()
  File "/usr/local/lib/python2.7/dist-packages/googletrans/gtoken.py", line 59, in _update
    code = unicode(self.RE_TKK.search(r.text).group(1)).replace('var ', '')
AttributeError: 'NoneType' object has no attribute 'group'

Does anyone know what is going on? thank you.

If you go deeper to library you see, that request to google translate site returns something like 503 error or other. For me it was 503 error and text:

This page appears when Google automatically detects requests coming from 
your computer network which appear to be in violation of the Terms of Service.
The block will expire shortly after those requests stop.

This traffic may have been sent by malicious software, a browser plug-in, 
or ascript that sends automated requests. If you share your network connection,
ask your administrator for help — a different computer using the same IP
address may be responsible. Learn more

Sometimes you may see this page if you are using advanced terms that robots
are known to use, or sending requests very quickly.

This means, and README of project says it:

If you get HTTP 5xx error or errors like #6, it’s probably because Google has banned your client IP address.

Try to use proxy.
