Introduction<\/strong><\/h1>

Object-oriented programming (OOP) is a method of organizing a program by grouping related properties and behaviors into separate objects. In this tutorial, you will learn the fundamentals of object-oriented programming in Python.<\/p>

Objects function conceptually similarly to system components. Consider a program to be similar to a factory assembly line. At each stage of the assembly line, a system component processes some material, eventually transforming raw material into finished goods.<\/p>

An object contains data, such as raw or preprocessed materials at each stage of an assembly line. In addition, the object contains behavior, such as the action that each assembly line component takes.<\/p>

What Is Python Object-Oriented Programming?<\/h1>

A programming paradigm known as object-oriented programming offers a way to organize programs so that various behaviors and properties are combined into single objects.<\/p>

For example, an object could represent a person by having properties such as a name, age, and address, as well as behaviors like walking, talking, breathing, and running. It could also represent an email with properties such as a recipient list, subject, and body, as well as actions such as attaching files and sending.<\/p>

To put it another way, object-oriented programming is a method for modeling concrete, real-world things like cars, as well as relationships between things like businesses and employees or students and teachers. OOP represents real-world entities as software objects with associated data and the ability to perform specific operations.<\/p>

The key takeaway is that objects are central to Python’s object-oriented programming paradigm. Other programming paradigms use objects to represent data. In OOP, they also influence the overall structure of the program.<\/p>

How Do You Define a Class in Python?<\/h1>

In Python, you define a class by typing the class keyword, followed by a name and a colon. Then, you use.init<\/strong>() to declare what attributes each instance of the class should have:<\/p>

<\/circle><\/circle><\/circle><\/g><\/svg><\/span><\/path><\/path><\/svg><\/span>
class<\/span> <\/span>Student<\/span>:<\/span><\/span>\n    <\/span>def<\/span> <\/span>__init__<\/span>(<\/span>self<\/span>, <\/span>name<\/span>, <\/span>age<\/span>):<\/span><\/span>\n        <\/span>self<\/span>.student_name<\/span>=<\/span>  name<\/span><\/span>\n        <\/span>self<\/span>.student_age <\/span>=<\/span> age<\/span><\/span><\/code><\/pre><\/div>
This code defines a class called Student<\/code> that has two attributes: student_name<\/code> and student_age<\/code>.<\/p>
