Object Oriented Programming (OOP) or known as object-oriented programming (OOP) is a form of paradigm in programming that uses an object as a form and basic unit to regulate and manage the program code that is created and wants to run. Python Programming Language is a type of programming language that supports Object Oriented Programming (OOP) and allows a programmer to create and operate an object easily.
In Object Oriented Programming (OOP), especially in the Python programming language, a program code is built using the concept of "object, which is the basic unit that represents a real or abstract entity in the system being built. Each object created by program code has an attribute or variable that defines each of its characteristics and methods with functions used to describe a behavior or action that can be performed by objects written according to the program code created. This concept helps in modeling a real world in computer code, thus facilitating the understanding and maintenance of programs for a programmer.
The first concept and that is often used in Object Oriented Programming (OOP) in the Python programming language is Class (class). Class is a concept in Object Oriented Programming (OOP) that is composed of basic constructions used to define a blueprint or image on the object of a program code. A class is an entity that describes the attributes of a variable and method with functions that will be owned by the object created from that class. Simply put, a class is a way to describe a new type of data with it as a property and based on a specific behavior.

The second concept of Object-Oriented Programming (OOP) in Python programming language is Object. An object is a concept consisting of a concrete instance or copy of a class. An object is a tangible manifestation of a blueprint or image that has been defined by a class. When a programmer creates an object from a Class, the programmer creates an entity that has the same attributes and behaviors defined in that Class.

The third concept of Object-Oriented Programming (OOP) in Python programming language is Inheritance. Inheritance is one of the important concepts in Object Oriented Programming (OOP) especially in Python Programming Language which is used to allow new classes to inherit attributes and methods from classes that have been created. In the context of Object-Oriented Programming (OOP) in Python, inheritance allows a programmer to create a hierarchy of classes, where child or child classes can inherit any characteristic derived from a parent class or superclass.
Inheritance is useful in situations where a coder has multiple classes that have similar attributes and methods and can avoid code duplication by grouping characteristics together into more abstract parent classes. In this way a program coder can pass an attribute and method from the parent class to the child class thus saving time and effort in developing and maintaining the program code.
