What Is Class?

Let's say you're a magician who needs to concoct various spells to defeat his foes. You could scribble the bits on paper, which could be more organized. In its place, you could compile a magical spellbook explaining each spell's purpose and how to cast it. A class in computer programming functions similarly to a magical spellbook in that it provides structure to data and details the capabilities of objects. Objects are to programming as spells are to the real world of magic. Classification allows for the identification of distinctive features and skills. Here, we see a sample class definition for Spell, which consists of three attributes (name, power, and element) and one method (cast spell). An instance of a class's __inits__ method is invoked whenever a new class instance is created. It accepts three arguments (the object's name, power, and element) and sets those values as the new object's properties. Object-oriented programming (OOP) is a programming style that focuses on making and working with objects and classes to simulate real-world situations. OOP is based on encapsulation, meaning information and behavior can be stored in the same entities. With OOP's inheritance feature, you can create a new class based on an existing one (called the parent or superclass). A child or subclass is a new class that extends another class and takes on its properties and methods. Polymorphism is another OOP feature that enables objects of different classes to be used interchangeably. A function may accept a Spell object as a parameter, but it may also take a parameter of a subclass of Spell. Your code will be more adaptable and reusable as a result of this. This explains it: classes are like books of spells, organizing data and describing the capabilities of objects. Master of the Code, we wish you the best of luck!
