How to use Django's include without a string literal?

I just started up with django.

Following this tutorial, I ended up with the following urls.py:

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('polls/', include('polls.urls')),
    path('admin/', admin.site.urls),
]

This links to polls.urls.py which has its own router.

The part I don't like is the string literal 'polls.urls' which is, well... a string literal.

I would like to somehow reference the file directly using some of python's power, and have AT LEAST my IDE protect me.

What happens if I want to move that polls.urls.py file, or rename it, or rename polls? Should I trust my IDE to catch a reference from a string literal?

This is almost like doing this monstrosity, and is very hard for me to accept as the best practice.

It just seems odd to me.

Is there a way to use something less prone to errors than string literals in django's routers?

I don't see problems with using string literals as URLconf is loaded prior to starting of server (runserver)

If there is a problem you would get ModuleNotFound error

From source of include() :

if isinstance(urlconf_module, six.string_types):
    urlconf_module = import_module(urlconf_module)

You would see good amount of import_module usage through Django framework and string literals.

Your IDE would know if there is unresolved reference (Pycharm does)

So from what I understand or what I know there are two ways of url mapping using the path' orurl`

for path method you bound to do what you did that is:

from django.urls import path, include

but you are to also import your views.py

For second method your are to:

from django.conf.urls import url

then your are to import your views there as: from .views import home_page home_page being a function or class in your views.py

Example of mapping url(r'^home/$', home_page),

so no need to actually to actually create urls.py if you use this method
