Python is an object-oriented programming language, which means it allows the creation and manipulation of objects that have certain properties and methods. In this article, we will take an in-depth look at Python’s object-oriented programming features, including classes, inheritance, and polymorphism.

Let us begin

Classes

In Python, a class is a blueprint for creating objects. Classes define the properties and methods that objects created from the class will have. Here is an example of a simple class called “Person”:

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age
    
    def say_hello(self):
        print("Hello, my name is " + self.name)

p = Person("John", 30)
p.say_hello() # Output: Hello, my name is John

In this example, the Person class has two properties, name and age, and one method, say_hello(). The __init__ method is a special method called a constructor, which is called when a new object is created from the class. The properties and methods of a class are defined within the class definition, but are only accessible from the objects created from that class.
