This book does not teach you to use a programming language but to understand how to write a program. How does a programmer think? How do you analyze a problem? How do you write a valid solution? Writing software is not rocket science, just pay attention and understand what the heart of the matter is: solving a problem. You will learn to solve problems by identifying a process or an algorithm, depicting it with a block diagram and then easily translating it into code. The book uses Scratch and Python but the method can be easily applied to any programming language.
