Django is a free and open-source web framework, written in Python. It is an amazing framework for web developers because it provides the infrastructure required for database-driven websites that have user authentication, content administration, contact forms, file uploads, and more. Django stands way out in front for ease of use and ability to allow a programmer to produce robust, secure, and bug free code quickly, very easy to switch database. Django offers a big collection of modules which you can use in your own projects. It is based on MVT (Model View Template) design pattern. The Model helps to handle database. The Template is a presentation layer which handles user interface part completely. The View is used to execute the business logic and interact with a model to carry data and renders a template. Django is designed in such a manner that it handles much of configure things automatically, so we can focus on application development only. It prefers conventions over configurations which means that it gives you a way of implementing some task and you have to stick to this method to implement it. You have less flexibility in that case but at the same time more secure and efficient because these conventions have been developed by thousands of active developers out there in the world.
