In your Django apps, use settings by importing the object django.conf.settings. Example:

from django.conf import settings
if settings.DEBUG:
     # Do something 

Note that django.conf.settings isn't a module-it's an object. So importing individual settings is not possible:

from django.conf.settings import DEBUG  # This won't work. 

Also note that your code should not import from either global_settings or your own settings file. django.conf.settings abstracts the concepts of default settings and site-specific settings; it presents a single interface. It also decouples the code that uses settings from the location of your settings.
