Django is a high-level Python web framework designed for rapid development and clean, pragmatic design. It provides built-in features like an ORM, an admin interface, and robust authentication, enabling developers to build secure and scalable web applications. Django emphasizes reusability and follows the "don't repeat yourself" (DRY) principle, reducing the amount of boilerplate code required. It is widely used for developing complex applications such as e-commerce platforms, content management systems, and social networks. Django's strong community support and extensive documentation make it a favorite among developers of all levels.
