Define Python Class
Overview
Let’s learn how to define a Python class in this tutorial. A class is a basic entity of an object-oriented programming language. It is a blueprint for creating objects. Classes encapsulate data and methods that operate on that data.
Define Python Class
A Python class can be defined by using the keyword ‘class‘.
Syntax
The general syntax for defining a class is as follows:
class PythonClassName:
‘optional class documentation string’
class definition
The class is defined by using the keyword class with the PythonClassName followed by a colon. An optional class documentation string can follow the class statement. This provides short information about the class being created. The class definition can have:
- class attributes
- constructor method
- instance attributes
- methods
Class members | Description |
Class Attributes | These are variables that are shared by all instances of the class. They are defined directly inside the class. |
Constructor Method | The __init__ method is a special method that Python calls when a new instance of the class is created. It is used for initializing the instance’s attributes. |
Instance Attributes | These are attributes specific to each instance of the class, usually defined within the __init__ method. |
Methods | These are functions that are defined inside a class and can perform operations using the class or instance attributes. |
