title: How to import names that start with a certain prefix from a module?
body: <p>I'm building a GUI in Python.</p>
  <p>I want to store the settings for the GUI in a separate module called <code>settings.py</code>. This settings module also contains some other variables/classes. But the GUI has settings that start with <code>L_</code>. I want to import from <code>settings.py</code> all the names that start with <code>L_</code>.</p>
  <p>How would I go about doing that?</p>
