OOP: Introduction 4 The Class Concept •A class is a collection of objects (or values) and a corresponding set of methods. •A class encapsulates the data representation and makes data access possible at a higher level of abstraction. •Example 1: A set of vehicles with operations for starting, stopping, driving, get km/liter, etc. In this article, you’ll learn about the Object Oriented Programming (OOP) in Python and their fundamental concept with examples. Introduction to OOPs in Python Python is a multi-paradigm programming language.

Object Oriented programming is a programming style that is associated with the concept of Class, Objects and various other concepts revolving around these two, like Inheritance, Polymorphism, Abstraction, Encapsulation etc. In the video below, we have explained the basic concepts of Object Oriented Programming with help of a very easy to understand example.
If you want to skip the video, everything is covered below as well. Let us try to understand a little about all these, through a simple example.
Human Beings are living forms, broadly categorized into two types, Male and Female. Its true. Every Human being Male or Female has two legs, two hands, two eyes, oops concepts with examples pdf download nose, one heart etc.
There are body parts that are common for Male and Female, but then there are some specific body parts, present in a Male which are not present in a Female, and some body parts present in Female but not in Males.
All Human Beings walk, oops concepts with examples pdf download, see, talk, hear etc. Now again, both Male and Female, performs some common functions, but there are some specifics to both, which is not valid for the other. For example : A Female can give birth, while a Male cannot, so this is only for the Female. Human Anatomy is interesting, isn't it?
Here we will try to explain all the OOPS concepts through this example and later we will have the technical definitons for all this. Here we can take Human Being as a class. A class is a blueprint for any functional entity which defines its properties and its functions, oops concepts with examples pdf download.
Like Oops concepts with examples pdf download Being, oops concepts with examples pdf download, having body parts, and performing various actions. Considering HumanBeing a class, which has properties like hands, legs, eyes etc, and functions like walk, talk, eat, see etc.
Male and Female are also classes, but most of the properties and functions are included in HumanBeinghence they can inherit everything from class HumanBeing using the concept of Inheritance. When we say, Human Being, Male or Female, we just mean a kind, you, oops concepts with examples pdf download friend, me we are the forms of these classes.
We have a physical existence while a class is just a logical definition. We are the objects. Abstraction means, showcasing only the required things to the outside world while hiding the details. Continuing our example, Human Being's can talk, walk, oops concepts with examples pdf download, hear, eat, but the details are hidden from the outside world.
We can take our skin as the Abstraction factor in our case, hiding the inside mechanism. This concept is a little tricky to explain with our example. Our Legs are binded to help us walk. Our hands, help us hold things.
This binding of the properties to functions is called Encapsulation. Polymorphism is a concept, which allows us to redefine the way something works, by either changing how it is done or by changing the parts using which it is done. Both the ways have different terms for them. If we walk using our hands, and not legs, here we will change the parts used to perform something. Hence this is called Overloading.
And if there is a defined way of walking, oops concepts with examples pdf download, but I wish to walk differently, but using my legs, like everyone else. Then I can walk like I want, this will be called as Overriding. Objects are the basic unit of OOP.
They are instances of class, which have data members and uses various member functions to perform tasks. It is similar to structures in C language. Class can also be defined as user defined data type but it also contains functions in it. So, class is basically a blueprint for object. Abstraction refers to showing only the essential features of the application and hiding the details. This can be done using access specifiers.
It can also be said data binding. Encapsulation is all about binding the data variables and functions together in class. Inheritance is a way to reuse once written code again and again. They are also called parent and child class. So when, a derived class inherits a base class, the derived class can use all the functions which are defined in base class, hence making code reusable.
It is a feature, which lets us create functions with same name but different arguments, which will perform different actions. That means, functions with same name, but functioning in different ways. Or, it also allows us to redefine a function to provide it with a completely new definition.
You will learn how to do this in details soon in coming lessons. Exception handling is a feature of OOP, to handle unresolved exceptions or errors produced at runtime. Made with by Abhishek Ahlawat.

Classes and objects (I) Class- user defined data blogger.comental packaging unit of OOP technology Class declaration is similar to struct declaration Keyword ‘class’ followed by class name. Object is an instance of class Object combines data and functions Object is created as a variable of class type using class name Members of class. OBJECT-ORIENTED PROGRAMMING (OOP) CONCEPTS WITH EXAMPLES Object-Oriented Programming (OOP) uses "objects" to model realworld objects. Object-Oriented Programming (OOP) consist of some important concepts namely Encapsulation, Polymorphism, Inheritance and Abstraction. These features are generally referred to as the OOPS concepts. In this page, we will learn about the basics of OOPs. Object-Oriented Programming is a paradigm that provides many concepts, such as inheritance, data binding, polymorphism, etc.. Simula is considered the first object-oriented programming language. The programming paradigm where everything is represented as an object is known as a truly object-oriented programming language.
