Where can I learn Django for free?

As other folks have said, Django is a web framework written in Python that uses OOP as a programming paradigm , and if you work in Django you will be doing OOP, that is, you will be writing classes that extend other classes, writing methods that override existing methods in base classes, etc.

as_view is the function(class method) which will connect my MyView class with its url . From django docs: classmethod as_view(**initkwargs) Returns a callable view that takes a request and returns a response: You just can’t use class-based views like you could in normal function-based views.

A view is a callable which takes a request and returns a response. This can be more than just a function, and Django provides an example of some classes which can be used as views. These allow you to structure your views and reuse code by harnessing inheritance and mixins .

Class: Class is basically a blueprint or a template for creating objects . Object: Collection of arguments and methods which can be performed on those data. An object is nothing but an instance of the class.
