Read MorePython program to print words from a sentence with highest and lowest ASCII value of characters
ASCII (American Standard Code for Information Interchange) is a character encoding system that represents every character as a unique 7-bit binary code. ASCII values range from 0 to 127, where each character has a specific numerical representation. For example, the ASCII code for a space character is 32, and for digit '1' it is 49. In Python, you can find the ASCII code of a character using the ord() function, which takes a character as input and returns its ASCII value. For example, ord('A') returns 65. Problem Statement Given a string, find and print the words that ...

Read MoreHow to Count Unique Values Inside a List in Python?
Python lists are fundamental data structures, and counting unique values within them is a common task in data analysis and processing. This article explores four different approaches to count unique values in a Python list, each with its own advantages depending on your specific needs. Using a Set The simplest method leverages Python's set data structure, which automatically removes duplicates. Converting a list to a set eliminates duplicate values, and len() gives us the count of unique elements. Example # Sample list with duplicates numbers = [1, 2, 3, 3, 4, 5, 5, 6, 7, ...
