from django.http import HttpResponse

def home(request):
    return HttpResponse("Hello Django!")
  

🔹 Step 2: Create App-Level URLs

# blog/urls.py
from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='home'),
]
  

🔹 Step 3: Include App URLs in Project

# mysite/urls.py
from django.contrib import admin
from django.urls import path, include

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

🔹 Step 4: Run Server

python manage.py runserver
