What is Django and why is it used in web development?

Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It follows the DRY (Don't Repeat Yourself) principle and aims to make web development simple and efficient. Django provides built-in features for authentication, URL routing, template engine, ORM (Object-Relational Mapping), and more, which can significantly speed up the development process.

Developers often choose Django for its robust security features, scalability, and extensive documentation. Its batteries-included approach means that many common web development tasks are already handled, allowing developers to focus on building their applications rather than reinventing the wheel.

Overall, Django is used in web development for its versatility, ease of use, and the ability to create complex, database-driven websites and web applications quickly and efficiently.
