Django is an open-source web framework based on Python, designed to facilitate the rapid development of secure and scalable web applications. Django follows the MVC (Model-View-Controller) pattern, which separates business logic from the user interface, making the code more organized and maintainable. This framework includes built-in tools for database management, such as PostgreSQL and MySQL, and offers a wide range of features, including an intuitive admin panel, a robust authentication system, and full support for internationalization.
