Django can be broken into many components:

Models.py file: This file defines your data model by extending your single line of code into full database tables and add a pre-built administration section to manage content.

Urls.py file: It uses a regular expression to capture URL patterns for processing.

Views.py file: It is the main part of Django. The actual processing happens in view.

When a visitor lands on Django page, first Django checks the URLs pattern you have created and used the information to retrieve the view. After that view processes the request, querying your database if necessary, and passes the requested information to a template.

After that, the template renders the data in a layout you have created and displayed the page.
