Unit 1 - Lesson 12 - Predefined Functions

Higher Computing Science Course Coverage Podcasts by Mr Graham

Episode notes

Welcome to this week's episode, where we're exploring Period 12: Predefined Functions! Today we're focusing on two essential types: conversion and modulus. Our goal is to help you implement predefined functions for character/ASCII conversion and modulus and understand their practical applications.

Understanding the Tools 🔧

We'll start by reviewing some of Python's most useful predefined functions, including ord(), chr(), int(), and the modulus operator (%). We'll discuss their utility in programming. For example, ord() and chr() are incredibly useful for tasks like input validation, converting characters to their numerical ASCII values, and even simple encryption. The modulus operator, which gives us the remainder of a division, is a go ...
