View source for Simple "Hello world" application

'''Start a project:'''<br>
''$ django-admin startproject lecture3''<br>
'''Change directory into the folder "lecture3:'''<br>
''$ cd lecture3<br>''
'''Run the webserver then navigate to http://localhost:8000 to check that it is working'''<br>
''$ python manage.py runserver'' <br>
'''Create a simple app called "hello"''' <br>
''$ python manage.py startapp hello'' <br>
This will create a folder called "hello" containing a variety of files<br>
'''In the lecture3 folder edit the settings.py file and add the hello app to the configuration'''
<source lang="python">
INSTALLED_APPS = [
    'hello',
    'django.contrib.admin'
</source>
'''In the hello folder edit the views.py file''' <br>
At the top of the file add "from django.http import HttpResponse" <br>
Then add 
<source lang="python">
 def index(request):
       return HttpResponse("Hello World")
</source>
'''Again in the "hello" folder create a urls.py file with the following contents:'''
<source lang="python">

    from django.urls import path
    from . import views
    urlpatterns={
        path("", views.index, name="index")
    }
</source>
'''In the lecture3 directory edit the urls.py file and add "include" to the import line, then add:'''
<source lang="python">
path('hello/', include("hello.urls")) 
</source>
so that the urls.py file in the lecture3 directory now looks like:
<source lang="python">
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('hello/', include("hello.urls"))
]
</source>
