💡 Problem Formulation: In the Minion game, two players create words from a given string. The player with the most points wins. A vowel opening a word scores points equal to the remaining length of the string. The task is to write a Python program that computes the scores and declares the name of the … Read more

💡 Problem Formulation: In Python, you may often need to manipulate list items. A common task is updating a list so that each element becomes the absolute value of the original element. For instance, given the input list [1, -4, 3, -2], the desired output would be [1, 4, 3, 2]. This article explores five … Read more

💡 Problem Formulation: Finding a better or ‘best’ divisor of a number means finding a divisor which is neither too high nor too low in its value. In an ideal situation, we strive to find divisors that are close to the square root of a number to avoid pairing small with large divisors. For instance, … Read more

💡 Problem Formulation: Python developers typically use the built-in len() function to find the length of a list. However, understanding alternative methods can improve one’s grasp of Python’s iterators and loops. This article aims to elucidate how to find the length of a given list, such as my_list = [1, 2, 3, 4], where the … Read more

💡 Problem Formulation: Given a list of numbers in Python, the task is to calculate the sum of all the odd numbers contained within it. For example, if the input is [1, 2, 3, 4, 5], the expected output is 9, since 1 + 3 + 5 = 9. Method 1: Using for-loop and Modulus … Read more

How to Reverse a List with List Slicing in Python 💡 Problem Formulation: How can a list in Python be reversed in place without using built-in functions? Given an input list [1, 2, 3, 4, 5], the desired output is a list in reversed order: [5, 4, 3, 2, 1]. This article demonstrates five ways … Read more

💡 Problem Formulation: When programming in Python, you may encounter scenarios where you need to generate a sequence of numbers from 1 to n as a list. This task forms the basis of many algorithms and is handy for generating test data, iterating over loops, numerical computations, and more. For example, if the input is … Read more

💡 Problem Formulation: You have a collection of height measurements but they include duplicate entries for individuals. Our goal is to compute the average height per individual, then, using only the distinct data points, to calculate the overall average height. Imagine input as a list of tuples ((‘Name’, Height_in_cm)), and the desired output is a … Read more

💡 Problem Formulation: In Python programming, it’s frequently necessary to interact with the user via the console. This interaction often involves prompting the user for input and then processing or displaying it according to the program’s needs. For instance, a program might require the user to enter their name, and then it might produce a … Read more

💡 Problem Formulation: Let’s discuss how to take a string, split it into a list of substrings based on a delimiter, and then join those substrings into a new string separated by commas. For instance, if our input is “apple orange banana”, the desired output would be “apple,orange,banana”. This is a common data manipulation task … Read more

💡 Problem Formulation: In the realm of text manipulation, a common operation is to invert the casing of letters in a word or sentence; that is, to convert lowercase letters to uppercase and vice versa. For instance, the input “Hello World” should be transformed into “hELLO wORLD”. Method 1: Using the swapcase() Method Python’s built-in … Read more

💡 Problem Formulation: Given a particular string, the task is to write a Python program that can generate all possible permutations of a given size ‘r’. For instance, if the input string is “ABCD” and ‘r’ is 2, the desired output would be all two-character permutations like “AB”, “AC”, “AD”, “BA”, “BC”, etc. Method 1: … Read more
