Why We Love Python
Open-source (It’s Free!!!) Cross-platform High-level dynamic object-oriented programming
language Supports structured programming - can be used for
procedural programming and limited support of functional programming
It's designed to be easy to program and easy to read Small core with large standard library and designed to
be highly extensible Language of choice for the open-source GIS world

Model–View–Controller Architectural Pattern
Simply put, MVC is way of developing software so that the code for defining and accessing data (the model) is separate from request-routing logic (the controller), which in turn is separate from the user interface (the view). - The Django Book
The idea is to maintain a loose coupling between the various components.
The Django Web Application is split across at least 4 components:1. models.py (Model)2. views.py (View)3. urls.py (Controller)4. html_template.html (HTML Templates)
