1. What is a Rational Number? A rational number is any number that can be expressed as a fraction where both the numerator and the denominator are integers (whole numbers), and the denominator is not zero. The key idea is ratio. The word “rational” comes from the word “ratio.” General Form:a / b Examples: Non-Examples: 2. Formulas for Addition and Subtraction…

Object-Oriented Programming: Generalization vs. Specialization Introduction Inheritance in OOP serves two primary purposes: Let’s explore these concepts with clear examples. 1. Specialization (Extending Functionality) Specialization involves creating a new class that inherits all features from a parent class and then adds new, specific features. The core idea is reusability—you build upon what already exists. Key Principle: Child Class =…

Operator Overloading in Python with Simple Examples Operator overloading allows you to define how Python operators (like +, -, *, etc.) work with your custom classes. This makes your objects behave more like built-in types. 1. What is Operator Overloading? 2. Basic Syntax python class ClassName: def __special_method__(self, other): # Define custom behavior 3. Common Operator Overloading Methods Operator…

Method overriding is a key feature of object-oriented programming (OOP) and inheritance. It allows a subclass (child class) to provide its own specific implementation of a method that is already defined in its superclass (parent class). When a method is called on an object of the child class, the child’s version of the method is…
