Before you can use Django, you’ll need to install it. Our complete installation guide covers all the possibilities; this guide will get you to a simple, minimal installation that’ll work while you walk through the introduction.

Write your first Django app
Open command prompt to create new django project we should write on terminal the following command :
>> django-admin startproject firstdemoproject
now we will move to the folder and create a new app inside project folder
>>cd firstdemoproject

it will create required folders inside the directory structure.
Register your App

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles','app1'
]
add your app name as the last entry in the file and save and close the file.
A view is a place where we put the "logic" of our application, a webpage is basically a view in django.
Adding code to views.py
from django.shortcuts import render
from django.http import request,HttpResponse
def homepage(request):
return HttpResponse("this is first page")
save and close the file.

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

>>python manage.py runserver
while your program is in running state ,open your browser and open url as follows :
