Python Web Dev

Introduction

Python web frameworks like Flask and Django allow building web apps efficiently. This blog introduces routing, templates, and deployment basics.

Description

Python web development frameworks such as Flask and Django provide tools to build dynamic web applications quickly. Flask is lightweight, while Django is full-featured with built-in ORM and admin.

Main Content

### Flask Basics - **Routing** – Define endpoints using `@app.route()`. - **Templates** – Use Jinja2 for rendering dynamic HTML. - **Request Handling** – Access form data via `request` object. - **Deployment** – Use WSGI servers like Gunicorn for production. ### Django Basics - **Project & App Structure** – Organize code into reusable apps. - **Models** – Define database tables using ORM. - **Views & Templates** – Render HTML or JSON responses. - **Admin Interface** – Built-in admin for content management. - **Deployment** – Use Gunicorn + Nginx or cloud platforms. ### Best Practices - Separate code into modular apps. - Use environment variables for configuration. - Apply input validation and security practices. - Optimize database queries with ORM and indexing.

Conclusion

Python web frameworks like Flask and Django simplify building scalable and maintainable web applications. Choosing the right framework depends on project requirements and complexity.
