title: Ask gettext about current language and translation source in Python
body: <p>I initialize <code>gettext</code> very simple like this in python3.</p>
  
  <pre><code>&gt;&gt;&gt; import gettext
  &gt;&gt;&gt; gettext.install('i18n-test', 'locales')
  &gt;&gt;&gt; print(_('Hello World!'))
  Hallo Welt!
  </code></pre>
  
  <p>Can I ask gettext which current language it uses (must not be the system default  <code>LANGUAGE</code>!) and where it opens the <code>.mo</code> file from?</p>
  
  <p>I can not see something like this in the API.</p>
