Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. It follows the model-template-views (MTV) architectural pattern and comes with a rich set of features out of the box, including an ORM (Object-Relational Mapping), authentication, and an admin interface. Django emphasizes reusability, modularity, and the "don't repeat yourself" (DRY) principle, allowing developers to build and scale web applications quickly and efficiently. It is particularly well-suited for data-driven applications and is known for its robustness, security, and scalability.
