title: django.conf import settings vs from project.settings import VAR
body: <p>I was reading this article here about <a href="https://docs.djangoproject.com/en/2.0/topics/settings/" rel="nofollow noreferrer">django settings</a></p>
  
  <p>I understand "that django.conf.settings isn’t a module – it’s an object." That's why I can't import variables. I only need the statement CURRENCIES in my settings. </p>
  
  <p>Is the right approach to do <code>from django.conf import settings</code> and then <code>var = settings.CURRENCIES</code> or can I do <code>from [projectname].settings import CURRENCIES</code></p>
  
  <p>Both is working for me. But I wonder if there is a recommended approach.</p>
