Object oriented programming (oops) python
- 1. OBJECT ORIENTED PROGRAMMING Made By Noshaba
- 2. WHAT IS OOP’S? OOP stands for "Object-Oriented Programming." It's a way of structuring your code in programming languages like C++,C# , python and java Objects are self-contained units that combine data (attributes or properties) and the functions (methods) that can operate on that data into a single entity.
- 3. DIFFERENCE BETWEEN PROCEDURAL AND OOP.. Data Organization: Procedural programming uses global variables for data, whereas OOP encapsulates data within objects. Code Structure: Procedural code is structured around functions, while OOP code is organized around objects and their methods. Data Access: In procedural programming, data is often accessible globally, leading to potential data conflicts. In OOP, data is encapsulated within objects, making it more controlled and secure. Reusability: OOP promotes code reusability through classes and inheritance, making it easier to create and reuse similar objects. In summary, the key difference lies in how data is organized and accessed: procedural programming uses global data and functions, while OOP encapsulates data and behavior within objects, providing better structure and control
- 4. WHY WE NEED FOR OOP? We need Object-Oriented Programming (OOP) in simple terms because it helps us build software more efficiently and make it easier to understand and manage. Certainly, let's simplify the need for Object-Oriented Programming (OOP) even further: Think of OOP as a way to make computer programs more organized and understandable, just like how we use folders to organize our files on a computer. Objects as Folders: In OOP, we treat different parts of our program as "objects," which are like folders. Each object contains its own stuff, like data and actions, just like folders can contain files.
- 5. Reuse and Efficiency: OOP allows us to reuse these objects in different parts of our program, similar to how we can use the same folder in various places on our computer. This makes our code more efficient and saves us from doing the same work over and over. Clean and Clear: Just as folders help us keep our files organized and easy to find, OOP helps us keep our code organized and easy to understand. We can see what each object does and how it relates to other objects. Flexibility: If we want to change or add something in one part of our program, we can do it without affecting other parts. It's like rearranging or adding files in one folder without disturbing the contents of other folders. So, OOP is like using folders to keep our computer files organized. It helps us reuse code, keep our code clean and understandable, make changes easily, and collaborate effectively when building software.
- 6. TECHNIQUE IN OOP Class: A class is like a blueprint or a template. It tells the computer how to create something. For example, a "Car" class is like a blueprint for making cars. It defines what a car should have (like wheels and a color) and what it can do (like drive and stop). public class Car { public string name; public string model; public void Greet() { Console.WriteLine("Hello, my car name is " + name); } }
- 7. OBJECT: An object is a real thing that was created using a class. It's like the actual car made from the "Car" blueprint. Each object can have its own unique characteristics and can do things based on what the class defined. In even simpler terms, a class is a plan, and an object is something made from that plan. For example, a "Recipe" (class) tells you how to make a cake, and the actual "Cake" (object) is what you bake using that recipe
- 8. Encapsulation: This is like putting a protective shield around an object's data (attributes) and methods. It keeps them safe from unwanted changes or access. You can only interact with an object through its defined methods, which maintain control and security. Inheritance: Inheritance is like passing down traits from parents to children. In OOP, you can create new classes based on existing ones. The new class inherits attributes and methods from the original class, making it easier to reuse code and build on existing functionality. Abstraction: Abstraction in Object-Oriented Programming (OOP) is a fundamental concept that focuses on hiding unnecessary details and showing only the essential features of an object. It's like creating a simplified interface for users to interact with, without needing to understand the complex inner workings. In simple terms, OOP is like playing with different types of toys (objects) that have their own unique features (attributes) and things they can do (methods). These toys are created based on specific blueprints (classes). Encapsulation keeps them safe and organized, inheritance lets you create new toys with shared features, and polymorphism allows you to use all your toys in a playful and flexible way.
