title: Django App not working: "Error: No module named app_name"
body: <p>I'm new to Django, and I can't figure out why my app isn't loading. I've created all the files: <code>models.py</code>, <code>views.py</code>, <code>urs.py</code> with default code in. But when I run <code>python manage.py runserver</code>, it says the following:</p>
  
  <p><code>Error: No module named app_name</code></p>
  
  <p>What am I doing wrong?</p>
