Each building would be an instance of the blueprint. We can actually create many different buildings using the same blueprint. Based on this description, the building is the object.
The design contains every detail about the building including material, size, and shape. You can think of a class as the design (or prototype) of a building. To understand what a class is, let's consider another example. Methods are functions that are defined inside a given python class. A Python class is a blueprint for creating objects. The functions are referred to as methods. These data variables are referred to as properties. Each Salesperson instance has certain data associated with it (monthly sales, perhaps) and functions that it can perform (cold calling, as an example).Īs you may have noticed, a class is different from a function in that it contains not just functions, but also data (stored in variables). If we needed to write this logic into a Python program, we would say that "Salesperson" is a class, while "Nick" is an instance of "Salesperson". Consider a company that employs salespeople where one of these salespeople is named 'Nick'. On the other hand, objects are instances of classes.Īn example could be helpful here. What are Python Classes?Ī class is a code template used to create objects. We will see this in examples later in this article. And hence, instantiation is the word we use to refer to the process of creating an object.Ī class object is created with the same name as the class. An object is also referred to as an instance.
The object's functions act on the data stored within the object. In Python, an object is an encapsulation of variables and functions into a single entity. What is a Python Class Object?įor you to understand Python classes, you will first need to understand what an object is.
In this article, I am going to teach you how to write Python classes - which are special constructs that programmers use to organize related items in an application. It also puts emphasis on objects, unlike procedure oriented programming languages that stress the importance of functions. When creating complex code, object-oriented programming allows you to re-use code, making it easy to maintain and scale. It is important for you to understand why object oriented languages are necessary in programming. OOP is methodology used by programmers that enables a system or program to be defined as a set of objects, which can be manipulated and controlled in a piece-by-piece manner. Python is an object-oriented programming (OOP) language.
