Rectangle Inheritance in OOP Python: Rectangle & Cuboid Example Inheritance in object-oriented programming (OOP) allows a new class (the child class) to inherit properties and methods from an existing class (the parent class). This is a powerful concept for code reusability ♻️ and establishing a logical “is-a” relationship between classes. For instance, a Cuboid is…

The primary use of a static method in Python classes is to define a function that logically belongs to the class but doesn’t need access to the instance’s data (like self) or the class’s state (like cls). They are essentially regular functions that are grouped within a class namespace. Key Characteristics and Use Cases General…

Class Variables Class variables are variables that are shared by all instances of a class. They are defined directly within the class but outside of any method. Unlike instance variables, which are unique to each object, a single copy of a class variable is shared among all objects of that class. They are useful for…

Instance Variables Instance variables are variables defined within a class but outside of any method. They are unique to each instance (object) of a class. This means that if you create multiple objects from the same class, each object will have its own separate copy of the instance variables. They are used to store the…

In Python classes, you can have different types of variables and methods, each with a specific scope and purpose. They are primarily categorized based on whether they belong to the class itself or to an object (instance) of the class. 1. Types of Variables Variables in a class are called attributes. a. Instance Variables 🧑‍💻…

🟥 Rectangle Properties Properties are the nouns that describe a rectangle. They are the characteristics that define a specific rectangle’s dimensions and position. Examples: 📐 Rectangle Methods Methods are the verbs that describe what a rectangle can do or what can be done to it. They are the actions that allow you to calculate information…

🚗 Car Properties ⚙️ Car Methods 🚗 Car Properties Properties are the nouns that describe a car. They are the characteristics or attributes that define a specific car’s state. Think of them as the data associated with a car object. Examples: ⚙️ Car Methods Methods are the verbs that describe what a car can do….

OOP in Python is a programming paradigm that uses objects and classes to structure code. It’s a way of organizing code into reusable and logical blocks, making programs easier to manage, understand, and scale. Instead of focusing on functions, OOP focuses on data and the behavior associated with that data. Core Concepts of OOP 1….

The regular expression r’;\s*(.*?);’ is used to find and extract text that is located between two semicolons. In summary, this expression finds a semicolon, then non-greedily captures all characters up to the next semicolon. This is an effective way to extract the middle value from a semicolon-separated string. Title 1 to 25 chars The regular…

A negative lookbehind assertion in Python’s re module is a zero-width assertion that checks if a pattern is not present immediately before the current position. It is written as (?<!…). It’s the opposite of a positive lookbehind and allows you to exclude matches based on what precedes them. Similar to the positive lookbehind, the pattern…
