TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

Your project’s TEMPLATES setting describes how Django will load and render templates. The default settings file configures a DjangoTemplates backend whose APP_DIRS option is set to True. By convention DjangoTemplates looks for a “templates” subdirectory in each of the INSTALLED_APPS.

Index View

from django.http import HttpResponse, Http404
from django.template import loader
from .models import Question


def index(request):
    latest_question_list = Question.objects.order_by('-pub_date')[:5]
    # output = ', '.join([q.question_text for q in latest_question_list])
    # return HttpResponse("Hello, world. You're at the polls index.")

    template = loader.get_template('polls/index.html')
    context = {
        'latest_question_list' : latest_question_list
    }
    return HttpResponse(template.render(context, request))

Urls.py

from django.urls import path

from . import views

app_name = 'polls'
urlpatterns = [
        path('', views.index,  name='index'),
        path('<int:question_id>/', views.detail, name='detail'),
        path('<int:question_id>/results/', views.results, name='results'),
        path('<int:question_id>/vote/', views.vote, name='vote'),

]
