Inheritance in Python

Image
Inheritance is a powerful feature in object-oriented programming that allows you to create new classes that are modified versions of existing classes. Inheritance makes it easier to reuse code and make your programs more efficient and organized. Creating a Subclass In Python, you can create a subclass by defining a new class and specifying the existing class as its parent: class ParentClass: def my_method(self): print("This is a method in the parent class") class ChildClass(ParentClass): pass In this example, ParentClass is the parent class, and ChildClass is the subclass. The pass keyword is used to indicate that the subclass has no additional methods or attributes. Overriding Methods You can modify the behavior of a method in the subclass by defining a method with the same name: class ParentClass: def my_method(self): print("This is a method in the parent class") class ChildClass(ParentClass): def my_method(self): print(...

Object-oriented programming concepts in Python

Introduction to OOP Object-oriented programming (OOP) is a programming paradigm that emphasizes the use of objects, which are instances of classes, to represent and manipulate data. OOP focuses on the object's behavior rather than the data, and encourages the reuse of code through inheritance and composition. Classes and Objects In Python, a class is defined using the class keyword, and objects are instances of classes. Classes can have attributes, which are variables that hold data, and methods, which are functions that can operate on that data. Here is an example: class Cat: def __init__(self, name, breed): self.name = name self.breed = breed def meow(self): print("Meow!") my_cat = Cat("Whiskers", "Siamese") print(my_cat.name) my_cat.meow() In this example, we define a Cat class with an __init__() method that sets the cat's name and breed attributes. We also define a meow() metho...
