Start a project:
$ django-admin startproject lecture3
Change directory into the folder "lecture3:
$ cd lecture3
Run the webserver then navigate to http://localhost:8000 to check that it is working
$ python manage.py runserver
Create a simple app called "hello"
$ python manage.py startapp hello
This will create a folder called "hello" containing a variety of files
In the lecture3 folder edit the settings.py file and add the hello app to the configuration

INSTALLED_APPS = [
    'hello',
    'django.contrib.admin'

In the hello folder edit the views.py file
At the top of the file add "from django.http import HttpResponse"
Then add

 def index(request):
       return HttpResponse("Hello World")

Again in the "hello" folder create a urls.py file with the following contents:

    from django.urls import path
    from . import views
    urlpatterns={
        path("", views.index, name="index")
    }
