In this Python Tutorial for Beginners Video, I am going to give the Introduction to Object-Oriented Programming (OOP). I will start with the differences between Procedural and Object-Oriented Programming. Then we will discuss why we need Object-Oriented Programming. What is Object-Oriented Programming. What are classes, what is an object, what are member variables and methods .

00:00:01 1 - Introduction to Object-Oriented Programming (OOP)
00:09:57 2 - Classes and Objects in Python (OOP)
00:20:13 3 - Python _init_ and self in class
00:32:04 4 - Is it possible to define multiple constructors in Python?
00:40:06 5 - Python Encapsulation
00:51:32 6 - Private methods in Python
00:57:42 7 - Python Inheritance
01:12:41 8 - How To Create Modules in Python 3
01:25:00 9 - Python Multiple Inheritance
01:30:28 10 - Python super()
01:38:06 11 - Python Operator Overloading
01:54:47 12 - Python Composition
02:00:23 13 - Python Aggregation + Difference in Aggregation and Composition
02:07:26 14 - Python Abstract Classes

Procedural Programming
----------------------------------------------
C, Pascal
unit – function
concentrates on creating functions
data and operations on the data are separated.
methodology requires sending data to procedure/functions.

Object-Oriented Programming
---------------------------------------------------------
C++, Java, Python
unit – class
centered on creating objects
Object: A single software unit that combines data and methods
Data in an object are known as attributes.
Procedures/functions in an object are known as methods.

In Python, everything is an object i.e. integers, strings, dictionaries, …
Class objects are instantiated from user-defined classes, other objects are from language defined types. Classes In python Can be defined anywhere in the program. In this video I am going to give you two Python Class examples.
