2.       Replace content of djangoproject/urls.py.

Urls.py :

"""djangoproject URL Configuration

 

The `urlpatterns` list routes URLs to views. For more information please see:

    https://docs.djangoproject.com/en/3.2/topics/http/urls/

Examples:

Function views

    1. Add an import:  from my_app import views

    2. Add a URL to urlpatterns:  path('', views.home, name='home')

Class-based views

    1. Add an import:  from other_app.views import Home

    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')

Including another URLconf

    1. Import the include() function: from django.urls import include, path

    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))

"""

from django.contrib import admin

from django.urls import path,include

 

urlpatterns = [

    path('admin/', admin.site.urls),

    path('',include('helloworld.urls')),

]

 

 

3.       Create folder templates in helloworld folder.

4.       Create a html file “home.html” in templates folder.

Home.html:

<html>

    <head>

        <title> Hello world</title>

    </head>

    <body>

        <div>

            <p>Home</p>

        </div>

        <div>

            <h1> Hey ees squad!!</h1>

            <p style="align:center;font-size: 80px;"> Hello World application </p>

            <br>

            <p> application worked successfully</p>

        </div>

    </body>

</html>

 

5.       Replace helloworld/views.py files by following content:

Views.py:

from django.shortcuts import render

 

# Create your views here.

def home(request):

    return render(request,'home.html')

 

 

6.       Create a file with name “urls.py” in helloworld folder (helloworld/urls.py) :

Urls.py:

from django.urls import path,include

from . import views

urlpatterns = [

    path('',views.home,name='Home'),

]

 

Now Run command “Python manage.py runserver” in vs code.

 

Hello world app has been developed successfully!!!.
