Python’s magic methods __new__ and __init__ play complementary roles in the lifecycle of an object: 👉 __new__ is a static method, primarily concerned with creating and returning a new instance of a class; it acts before the object is fully instantiated in memory. 👉 Following this, __init__ functions as an instance method, tasked with configuring … Read more
Problem Formulation You’re given a number. How do you check if the number lies between two numbers, i.e., a numeric range? When you check if a number lies between two other numbers it returns a boolean that determines if the number is greater than or equal to the minimum number and also less than or … Read more
Creating a Python list that counts down from 10 to 1 can be done in several efficient and interesting ways. Below, I explore ten different methods to achieve this, each with an explanation and a code snippet. Method 1: Using range() The range() function is versatile and commonly used for generating sequences of numbers. It … Read more
Python offers several powerful options to handle file operations, including deleting files. Whether you need to check if a file exists before deleting, use patterns to delete multiple files, or automatically delete files under certain conditions, Python has a tool for you. Let’s delve into various ways you can delete files using Python, ranging from … Read more
Creating a list containing a range of numbers from 1 to N in Python can be achieved through several methods. Here’s a concise list of alternative solutions: Method 1. List Comprehension with range() This method utilizes list comprehension, a concise way to create lists. The range(1, N+1) generates numbers from 1 to N, and the … Read more
Python’s elegance and readability often come from its ability to execute powerful operations in a single line of code. One such instance is the combination of for loops and if statements into a list comprehension. Understanding the Basics At its core, a list comprehension offers a succinct way to create lists. The syntax [expression for … Read more
Imagine you and your friend are trying to decide who goes through the door first. You say, “After you,” and your friend says, “No, no, after you.” And there you both stand… forever. In Python, this happens when Module A needs something from Module B, but Module B also needs something from Module A. It’s … Read more
To generate random samples from a power-law distribution in Python, use the numpy library for numerical operations and matplotlib for visualization. Here’s a minimal code example to generate and visualize random samples from a power-law distribution: First, we import the necessary libraries: numpy for generating the power-law distributed samples and matplotlib.pyplot for plotting. The a … Read more
💡 Problem Formulation: This article addresses how one can identify odd numbers using the Python programming language. We define an odd number as an integer which is not divisible by 2 without a remainder. For instance, given the input 7, the desired output is a confirmation that 7 is indeed an odd number. Method 1: … Read more
💡 Problem Formulation: Determining the parity of an integer in Python involves checking whether it is divisible by 2 without any remainder. Typically, you might have an integer n and you want to get back a Boolean value, True if n is even, and False if it is not. For example, given n = 4, … Read more
💡 Problem Formulation: In Python, you may often need to convert an iterable, such as a list or a tuple, into a set. This is particularly useful when you want to eliminate duplicate elements and unorder the collection. Suppose you have a list [‘apple’, ‘banana’, ‘apple’, ‘orange’] and you want to convert it into a … Read more
👉 Problem Formulation: In Python, you often need to create a list of tuples, for instance, to pair items from two different lists or to represent data structures such as (key, value) pairs in a list. Given two lists, list1 and list2, the desired output is a list of tuples with each tuple containing one … Read more
