In object-oriented programming, inheritance allows us to create new classes that inherit the properties and methods of an existing class. This powerful concept enables code reuse, modularity, and extensibility in our programs. Before diving into accessing parent class attributes, let's have a quick refresher on inheritance. In Python, when a class inherits from another class, it acquires all the attributes and methods defined in the parent class. This mechanism allows us to create specialized classes that inherit and extend the functionality of a more general base class. The derived class is also known as a child class, while the class ...

In many programming scenarios, we often come across the need to find all possible combinations of a certain size from a given set of elements. These combinations can be useful in various applications such as generating permutations, solving combinatorial problems, or exploring different subsets of data. In this blog post, we will explore an efficient approach to find all unique combinations of size K until a given number N using the Python programming language. Understanding the Problem Before we dive into the solution, let's clearly define the problem we are trying to solve. Given a range of numbers from 1 ... Read More
The cryptographic algorithms AES (Advanced Encryption Standard) and RC4 (Rivest Cipher 4) are both used for encryption; however, they differ significantly in terms of security, usage, and design. Read this article to find out more about AES and RC4 and how they are different from each other. What is AES? AES (Advanced Encryption Standard) is a popular symmetric block cipher encryption algorithm for protecting sensitive data. It was chosen in 2001 by the United States National Institute of Standards and Technology (NIST) to replace the outdated Data Encryption Standard (DES) as the new encryption standard. Key Features of AES ... Read More
In many programming scenarios, there arises a need to find all possible pairs within a given list. Whether you're analyzing data, solving algorithmic problems, or working on a machine learning project, finding these pairs can be crucial for uncovering meaningful insights. In this article, we will explore different approaches to efficiently find all possible pairs in a list using Python. We'll discuss both brute-force and optimized solutions, along with their time complexities. Brute-Force Approach The brute-force approach is straightforward and involves iterating through the list twice to generate all possible pairs. Let's see the implementation − Example def find_all_pairs_brute_force(lst): ... Read More
