Python: Goslate translation request returns “503:

问题:

A few months ago, I used Python's goslate package to translate a bunch of French text to English. When I tried to do so this morning, though, the service returned an error:

import goslate
gs = goslate.Goslate()
print gs.translate('hello world', 'de')

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\Python27\lib\site-packages\goslate.py", line 389, in translate
    return _unwrapper_single_element(self._translate_single_text(text, target_language, source_language))

Does anyone know what happened to goslate? If it's gone for good, are there decent alternatives to the goslate package for translating French to English via an API call?

Please make sure you're using the newest version of Goslate and if not, try updating it from its repository. There were some changes in the API this month, and they are implemented in Goslate already. I've just checked it in my app, it does work flawlessly.
In order to update Goslate, you may need to install Mercurial version controlling system.
After installing Mercurial, clone the repo with this command:

hg clone https://bitbucket.org/zhuoqiang/goslate

and then update it from time to time like this (you need to be in the repository folder for this to work):

hg pull -u
