String Manipulation – Lesson Code
Learning Objectives In this post we will focus on string manipulation techniques using five common techniques used in most procedural programming languages: LEFT: to extract characters at the beginning of a string, RIGHT: to extract characters at the end of…
Molecular Mass Calculator
Learning Objectives In this challenge you will improve your string manipulation techniques as well as use Python to perform some basic mathematical calculations. Did you know? The molecular weight (mass) may be calculated from the molecular formula of the substance;…
The Gruffalo
This challenge is inspired from Julia Donaldson and Alex Sheffler’s children book: “The Gruffalo”. In this story a little mouse describes a ferocious animal/monster called a “Gruffalo” to scare other dangerous animals (fox, snake, owl) she encounters while taking a…
Scrabble Challenge
This challenge consists of creating a computer program that displays a random selection of 7 letters to the end-user. Each letter is given a value based on the values used in the game of Scrabble. The user is then asked…
The YOLO Challenge
The YOLO challenge consists of creating an acronym generator: a program that prompts the user to enter an expression or a sentence (e.g. “You only live once!”) and in return gives the acronym matching the user input (e.g. “YOLO”) Learning…
My E-Mail Validation Script
The aim of this challenge is to write a computer program that asks the end-user to type their e-mail address. The program should decide whether the e-mail being entered is a valid one or not. Some of the validation checks…
Python Patterns
Here is a quick challenge to focus on the use of loops, nested loops and string manipulation using Python. Let’s look at the following code: for i in range(0,9): st="" for j in range(0,i): st = st + " "…
