Python Classes with Examples

Introduction to Python Classes:

Classes are the building blocks of object-oriented programming (OOP) in Python. They encapsulate data and functionality into objects, promoting code reusability and modularity. At its core, a class is a blueprint for creating objects, defining their attributes (variables) and methods (functions).

Syntax of a Python Class:

class ClassName:

    # Class variables

    class_variable = value

    

    # Constructor

    def __init__(self, parameters):

        self.instance_variable = parameters

        

    # Instance method

    def method_name(self, parameters):

        # method body

Class Variables: Variables shared by all instances of a class. Constructor (init): Initializes instance variables when an object is created. Instance Variables: Variables unique to each instance. Instance Methods: Functions that operate on instance variables.

class Car:

    # Class variable

    wheels = 4

    

    # Constructor

    def __init__(self, brand, model):

        # Instance variables

        self.brand = brand

        self.model = model

    

    # Instance method

    def display_info(self):

        print(f"{self.brand} {self.model} has {self.wheels} wheels.")


# Creating objects of Car class

car1 = Car("Toyota", "Camry")

car2 = Car("Honda", "Accord")


# Accessing instance variables and calling methods

car1.display_info()  

car2.display_info()  


Toyota Camry has 4 wheels.

Honda Accord has 4 wheels.
