Define Python Class. We use the class keyword to create a class in Python. For example, class ClassName: # class definition . Here, we have created a class named ClassName. Let's see an example, class Bike: name = "" gear = 0. Here, Bike - the name of the class; name/gear - variables inside the class with default values "" and 0 respectively.

In Python, creating a class is as simple as using the class keyword: class Car: def __init__(self, make, model, year): self.make = make self.model = model self.year = year def get_description(self): return f"{self.year} {self.make} {self.model}" The __init__ method is a special method called a constructor. It initializes a new object with the ...

Dec 15, 2024 · In this tutorial, you’ll learn how to define and use Python classes, understand the distinction between classes and objects, and explore methods and attributes.

1. Class Attributes in Python. Class attributes are variables that are declared inside the class and outside methods. These attributes belong to the class itself and are shared by all objects of the class. Example of Python Class Attributes. class Vehicle: wheels = 4 car = Vehicle() van = Vehicle() print(car.wheels) print(van.wheels) Output

Dec 15, 2024 · Object-oriented programming in Python involves creating classes as blueprints for objects. These objects contain data and the methods needed to manipulate that data. The four key concepts of OOP in Python are encapsulation, inheritance, abstraction, and polymorphism.
