Django
Django is a high-level, open-source Python web framework designed to encourage rapid development and clean, pragmatic design. It follows a "batteries-included" philosophy, providing built-in, ready-to-use components for common web development tasks such as user authentication, site administration, database ORM (Object-Relational Mapping), and RSS feeds, allowing developers to focus on building their apps without reinventing the wheel. Built on the Model-View-Template (MVT) architecture, Django promotes the "Don't Repeat Yourself" (DRY) principle to make code maintainable and reusable. It is designed to handle the complexities of web development, offering high security against common threats like SQL injection and CSRF, while also being highly scalable for, and used by, high-traffic sites such as Instagram, Pinterest, and Disqus.
