What is Django?
Django is a high-level Python web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers, it takes care of much of the hassle of web development, so you can focus on writing your app without needing to reinvent the wheel. It is free, open-source, and powers some of the most heavily-trafficked sites on the internet.
The 'Batteries-Included' Philosophy
Django follows a 'batteries-included' philosophy. This means that common tasks—such as user authentication, content administration, site maps, and RSS feeds—are provided out of the box. Unlike Flask, where you must choose and install third-party libraries for these features, Django provides them as part of the core framework.
Core Architecture: MVT
Django uses the Model-View-Template (MVT) architectural pattern. It is similar to the well-known MVC (Model-View-Controller) pattern but with a slight twist in terminology and responsibility.
- Model: The data access layer. It handles everything related to the data and the database.
- Template: The presentation layer. It handles how the data is displayed to the user.
- View: The business logic layer. It bridges the Model and the Template, processing the logic and returning the response.
