MRO is a mechanism to resolve the method to be executed when super notation is used. A common confusion occurs in case of multiple inheritance. What if a common method is implemented in multiple parents and it is called using super(), from which class should the method be called? This is...
This section describes what is a class - a user defined datatype which is associated with a predefined set of properties and operations (also called methods).
This section describes what is a constructor - a special method to be invoked automatically when a new object is created from a class. The main purpose of the constructor is to provide initial values to object properties.

One of the fundamental principles of OOP is polymorphism, where objects of different classes can be treated as instances of a common superclass. Abstract classes play a key role in achieving this polymorphism by defining method signatures that derived classes must implement. It facilitates generic...
While this approach can be powerful, it is often controversial due to its potential risks and implications. Read More: Understanding Monkeypatch in Pytest Example of Monkey Patching In Python, you can override a method of a class without altering its source code: # Original class class Animal:...
Method Overriding: Subclasses can override superclass methods. When a method is called on an instance of the subclass, Python first looks for the method in the subclass. If not found, it looks for a method in the superclass. Single Inheritance: Python supports single inheritance, which means ...
polymorphism and method overriding go hand in hand. method overriding is the process of providing a different implementation of a method in a subclass that is already defined in its superclass. this is achieved by using the same method signature in the subclass as the one in the superclass. ...
When a variable is hidden, you can use super.variableName to access the value from a superclass. Here is an example of variable hiding in Java: public class Parent { int age = 30; } class Child extends Parent { int age = 4; public void age() { System.out.println("Parent's age:...
