title: python string prefixed with _, what is it?
body: <p>I see _ in some code before strings, e.g.</p>
  
  <p><code>lable = _("Password")</code></p>

  <p>Many thanks for your help.</p>
  
  <p>.

  <pre><code>from django.utils.translation import ugettext, ugettext_lazy as _
  </code></pre>
  
  <p>'-' is a shorthand...</p>
