There are a number of issues with this approach.įirst, it can make larger code files more difficult to manage. The key takeaway is that objects are at the center of object-oriented programming in Python, not only representing the data, as in procedural programming, but in the overall structure of the program as well. OOP models real-world entities as software objects that have some data associated with them and can perform certain functions.Īnother common programming paradigm is procedural programming, which structures a program like a recipe in that it provides a set of steps, in the form of functions and code blocks, that flow sequentially in order to complete a task. Put another way, object-oriented programming is an approach for modeling concrete, real-world things, like cars, as well as relations between things, like companies and employees, students and teachers, and so on. Or it could represent an email with properties like a recipient list, subject, and body and behaviors like adding attachments and sending. Object-oriented programming is a programming paradigm that provides a means of structuring programs so that properties and behaviors are bundled into individual objects.įor instance, an object could represent a person with properties like a name, age, and address and behaviors such as walking, talking, breathing, and running. What Is Object-Oriented Programming in Python?

At each step of the assembly line a system component processes some material, ultimately transforming raw material into a finished product.Īn object contains data, like the raw or preprocessed materials at each step on an assembly line, and behavior, like the action each assembly line component performs. Think of a program as a factory assembly line of sorts.

In this tutorial, you’ll learn the basics of object-oriented programming in Python.Ĭonceptually, objects are like the components of a system. Object-oriented programming (OOP) is a method of structuring a program by bundling related properties and behaviors into individual objects.
