Namespace is an important concept in Django. By introducing the namespace parameter, an entire app will have a "namespace" association. The namespace argument is introduced at the project level urls.py file. Once introduced, the namespace argument will allow the django app (and the other apps in the project) to resolve the path to find templates and methods of the app. This enhances portability/modularity of the app (you will be able to use your app in other projects) and can have multiple routes/instances of your app running on the same project.

Check out this documentation:

https://docs.djangoproject.com/en/2.1/topics/http/urls/#url-namespaces

I am paraphrasing what I think is the important code from the documentation

# filename: urls.py
# NOTICE THAT WE CAN USE SAME APP ON DIFFERENT ROUTES (author-polls and publisher-polls)
from django.urls import include, path

urlpatterns = [
    path('author-polls/', include('polls.urls', namespace='author-polls')),
    path('publisher-polls/', include('polls.urls', namespace='publisher-polls')),
]

Note that with the namespace, 'author-polls:index' will always resolve to the index page of the instance 'author-polls' (and likewise for 'publisher-polls') .

I hope this helps. Django is one of the most powerful frameworks for building secure/scalable/robust applications!
