Key Features
Routing & Views
Define URL routes and view functions to handle HTTP requests and responses.
API Development
Build RESTful and async APIs using Flask’s decorators, Django REST Framework, or FastAPI’s type hints.
ORM & Database
Use Django ORM, SQLAlchemy, or Tortoise ORM to interact with databases.
Performance & Scalability
FastAPI supports async I/O, Flask is minimal and extensible, Django scales with built-in tools.
How It Works
Choose Framework
Pick Django for full-stack apps, Flask for flexibility, or FastAPI for async APIs.
Install Framework
Use pip: `pip install django`, `flask`, or `fastapi[all]`.
Define Routes
Create views or endpoints using decorators and route handlers.
Connect Database
Use ORM or raw SQL to interact with SQLite, PostgreSQL, or MySQL.
Run & Deploy
Start dev server and deploy using Gunicorn, Docker, or cloud platforms.
Code Example
# Django View
def hello(request):
return HttpResponse("Hello from Django!")
# Flask Route
@app.route("/")
def hello():
return "Hello from Flask!"
# FastAPI Endpoint
@app.get("/")
def hello():
return {"message": "Hello from FastAPI!"}Use Cases
Web Applications

RESTful APIs
Build APIs with Flask or FastAPI for mobile, frontend, or microservices.
Async Services
FastAPI supports async endpoints for high-performance workloads.
Rapid Prototyping
Flask and FastAPI enable quick MVPs with minimal setup.
