What is a Python Framework?
A Python framework is a collection of modules and packages designed to streamline the development process by providing reusable code and tools. These frameworks help developers to build applications more efficiently by offering built-in solutions for common tasks such as database interaction, URL routing, and HTML templating.
Top Python Frameworks in 2024
1. Django
Overview
Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It’s known for its "batteries-included" approach, offering a wide range of built-in features.
Features
- ORM (Object-Relational Mapping): Simplifies database operations.
- Admin Interface: Auto-generated admin panel.
- Security: Built-in protection against common security threats.
- Scalability: Suitable for large-scale applications.
Getting Started with Django
# Install Django
pip install django
# Create a new project
django-admin startproject myproject
# Run the development server
cd myproject
python manage.py runserver
Advanced Usage
- Custom Middleware: Create middleware to handle requests and responses.
- Rest Framework Integration: Build RESTful APIs.
# Install Django Rest Framework
pip install djangorestframework
# Add to INSTALLED_APPS in settings.py
INSTALLED_APPS = [
...,
'rest_framework',
]
2. Flask
Overview
Flask is a lightweight WSGI web application framework. It is designed with simplicity and flexibility in mind, making it ideal for small to medium-sized applications.
Features
- Minimalistic: Core functionality with extensions for added features.
- Flexible: Suitable for both simple and complex applications.
- Micro-framework: No ORM, no form validation, or other components where third-party libraries can be chosen.
Getting Started with Flask
# Install Flask
pip install flask
# Create a simple app
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello_world():
return 'Hello, World!'
if __name__ == '__main__':
app.run()
Advanced Usage
- Blueprints: Structure large applications into modules.
- Flask-SQLAlchemy: Database integration.
# Install Flask-SQLAlchemy
pip install flask-sqlalchemy
# Configure SQLAlchemy
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///site.db'
db = SQLAlchemy(app)
3. FastAPI
Overview
FastAPI is a modern, fast (high-performance) web framework for building APIs with Python 3.7+ based on standard Python type hints.
Features
- High Performance: Asynchronous capabilities.
- Easy to Use: Automatic generation of OpenAPI and JSON Schema.
- Validation: Uses Pydantic for data validation.
Getting Started with FastAPI
# Install FastAPI and Uvicorn
pip install fastapi uvicorn
# Create a simple app
from fastapi import FastAPI
app = FastAPI()
@app.get("/")
async def read_root():
return {"Hello": "World"}
if __name__ == "__main__":
import uvicorn
uvicorn.run(app, host="127.0.0.1", port=8000)
Advanced Usage
- Dependencies: Use dependency injection.
- Background Tasks: Perform tasks in the background.
from fastapi import BackgroundTasks, FastAPI
app = FastAPI()
def write_log(message: str):
with open("log.txt", mode="a") as log:
log.write(message)
@app.post("/send-notification/")
async def send_notification(email: str, background_tasks: BackgroundTasks):
background_tasks.add_task(write_log, f"Notification sent to {email}")
return {"message": "Notification sent"}
4. Pyramid
Overview
Pyramid is a flexible, "start small, finish big" Python web framework. It is designed to scale with your application as it grows.
Features
- Flexibility: Use different templating languages, ORMs, etc.
- URL Mapping: Routes and views.
- Extensible: Add-on system for extending functionality.
Getting Started with Pyramid
# Install Pyramid
pip install pyramid
# Create a simple app
from wsgiref.simple_server import make_server
from pyramid.config import Configurator
from pyramid.response import Response
def hello_world(request):
return Response('Hello, World!')
if __name__ == '__main__':
with Configurator() as config:
config.add_route('hello', '/')
config.add_view(hello_world, route_name='hello')
app = config.make_wsgi_app()
server = make_server('0.0.0.0', 6543, app)
server.serve_forever()
Advanced Usage
- Security: Implement authentication and authorization.
- Traversal: Create hierarchical URL structures.
from pyramid.security import Allow, Everyone
class RootFactory:
__acl__ = [(Allow, Everyone, 'view'),
(Allow, 'group:editors', 'edit')]
def __init__(self, request):
pass
5. Tornado
Overview
Tornado is a Python web framework and asynchronous networking library, originally developed at FriendFeed.
Features
- Asynchronous: Non-blocking network I/O.
- WebSockets: Support for real-time web applications.
- Scalable: Designed for handling long-lived network connections.
Getting Started with Tornado
# Install Tornado
pip install tornado
# Create a simple app
import tornado.ioloop
import tornado.web
class MainHandler(tornado.web.RequestHandler):
def get(self):
self.write("Hello, World!")
def make_app():
return tornado.web.Application([
(r"/", MainHandler),
])
if __name__ == "__main__":
app = make_app()
app.listen(8888)
tornado.ioloop.IOLoop.current().start()
Advanced Usage
- WebSockets: Real-time communication.
- AsyncIO Integration: Use with Python's async/await syntax.
import tornado.web
import tornado.websocket
import tornado.ioloop
class EchoWebSocket(tornado.websocket.WebSocketHandler):
async def open(self):
print("WebSocket opened")
async def on_message(self, message):
self.write_message(f"You said: {message}")
async def on_close(self):
print("WebSocket closed")
def make_app():
return tornado.web.Application([
(r"/websocket", EchoWebSocket),
])
if __name__ == "__main__":
app = make_app()
app.listen(8888)
tornado.ioloop.IOLoop.current().start()
