Here are some Python hacks for competitive programming that can help you write efficient and concise code. String Operation Join Synatx Example Perform join in integer Solution Dictionary When using a dictionary as an iterable, the returned values are the keys, not the values. Just like are searching whether a key exists in hash/dict, but … Read more
Understanding Metaclasses in Python
In Python, metaclasses are a powerful and advanced feature that allows developers to control the behavior of class creation. While they may seem complex at first, understanding metaclasses can provide deep insights into Python’s object-oriented nature. What is a Metaclass? A metaclass is a class that defines how other classes behave. Just like a class … Read more
Class Methods, Static Methods, and Instance Methods in Python
Python provides three types of methods in a class: Instance Methods, Class Methods, and Static Methods. Each serves a different purpose and is used based on the requirement. In this article, we’ll explore these methods with examples to understand their differences and use cases. Instance Methods Instance methods are the most commonly used methods in … Read more
Python’s Dunder (Magic) Methods with Examples
Python provides a set of special methods, also known as dunder (double underscore) methods or magic methods, that allow developers to define how objects of a class interact with built-in functions and operators. These methods begin and end with double underscores (__method__) and enable customisation of object behavior. Object Creation & Initialization These methods control … Read more
