What is Django and Why Use It?

Django is a web framework built with the Python programming language. Django's official description claims that it enables developers to build high-performing, elegant web applications quickly. But what does that mean to you? That question is what we'll answer here.

A framework like Django does two primary things:

1) It provides functionality that web applications perform over and over again. Let’s take look at user management as an example. There are various housekeeping chores that a program or app performs every time someone logs in: authentication, database permissions, password management, and displaying pre-built forms.

Of course you can rewrite this functionality for every web application, but why reinvent the wheel? Most web applications require user authentication, so why not use an authentication system that's already been built? You'll save an enormous amount of time and can focus your efforts on the parts of the application that make it unique.

Django offers tools for lots of functions, not just user management. It provides pre-built tools for database management, URL design, forms, templates, and much more.

2) The second thing the framework does is to provide a methodology for completing tasks. If you want to create a web form to gather user data, there's a very specific place that you put the code that creates the forms, and there's a very specific way that you code them. While there's an enormous amount of flexibility, using Django components also requires using specific methods to accomplish certain tasks.

The value in this is apparent on projects that go beyond a few pages or are functionally complex. Knowing how to write code, where to put code, and where to find code in larger projects can make the maintenance and evolution of the code much easier as time goes by.

In summary, Django is a web framework that provides a significant amount of pre-built functionality, reducing the time it takes you to complete projects. It prescribes a certain methodology for building applications, which is helpful in deciphering complex applications.
