Create:

mysite/
    news/
        templates/
            news/
                index.html
 

Converting Index to TemplateView and defining the template to be index.html

from django.views.generic import TemplateView

class Index(TemplateView):
    template_name = 'news/index.html'

Some text for the template:

<h1>Hello World!</h1>

URLs (Routing)
 

To keep everything organized, we create a urls.py file for each app we create.

from django.urls import path
from news.views import *

urlpatterns = [
    path('', Index.as_view(), name="index"),
]

Then it's a matter of including each app urls.py file in the main urls.py file.

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

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

]
