Install Python & Django

Step 1: Install Python & Django

Make sure you have Python installed. Check by running:

python --version

If not installed, download it from Python.org.

Now, install Django:

pip install django

Step 2: Create a Django Project

Navigate to your desired folder in the terminal and run:

django-admin startproject myproject
cd myproject

Step 3: Run the Development Server

python manage.py runserver

Open http://127.0.0.1:8000/ in your browser—you should see the Django welcome page! 🎉

Next Steps:

Create a Django App:

python manage.py startapp myapp

Register the App in settings.py:

Add 'myapp' to the INSTALLED_APPS list.

Create a Basic View:

Open myapp/views.py and add:

from django.http import HttpResponse def home(request): return HttpResponse("Hello, Django!")

Map a URL:

In myapp/urls.py (create if not exists):

from django.urls import path from .views import home urlpatterns = [ path('', home), ]

Then, in myproject/urls.py, include it:

from django.urls import include, path urlpatterns = [ path('', include('myapp.urls')), ]

Run the server again and visit http://127.0.0.1:8000/ to see "Hello, Django!".
