Why Django?
Django is a Python Web Framework which works on method called MVT ["Model View Template"] and simply means every page has it's own functionality and you know very precisely where every stuff should be there. In short, Django works in a semantic manner or consistent manner.
AdvanTages of django framework
More Secure - Django manages your accounts and passwords in most secure way. And avoids mistakes of putting Session information in Cookies where it is vulnerable and directly storing password rather than using Password Hash.
Versatile - Using Django we can develop any kind of Web Applications.
Maintainable - Django works on principle "DRY - DON'T REPEATYOURSELP". In simple terms to avoid duplication or all web pages must have their unique features and functionalities.
Inheritance - Best feature which Django provides is Inheritance. Let's assume you want to apply Navbar in all pages except Login and Register Page. Create different page for Navbar and inherit in other pages simply using keyword " {%include 'navbar.html' %}".
Portable - Django can run on multiple Platforms. That means that you are not tied to any particular server platform, and can run your applications on many flavours of Linux, Windows, and Mac OS X.
Scalable - Example: You own a website and you see sudden increase in Traffic on your Website. Django will scale your servers automatically.
What is Web-Framework? It means there are few sets of Patterns or Standard. For developing website it will provide Standard Template to develop website with help of tools
How Django Works?
When user makes HTTP Request what happens is Django Controller will go to URLS.PY where all sets of URL Patterns are available. Further it will search for appropriate request in VIEWS.PY where all sets of Templates[In other terms Web Pages] will be available and if it's valid request it will give you HTTP Response in HTML format.
MODELS.PY - All User credentials such as accounts and Passwords will be managed here. Simply, it stores and maintain the data.

WHAT IS MVT?
MODELVIEWTEMPLATE If we look at the 3-tier architecture of an app. Views are like the business logic layer. It is the controller in a typical MVC (Model View Controller) design but Django has a slightly different naming convention called MVT (Model View Template) where: Model is the data access layer, View is the business logic layer and Template is the presentation layer.
