Glossary

Sometimes, when you’re programming for the first time, you’ll encounter a new term that just doesn’t make much sense. That lack of understanding can get in the way of making any real progress. But there’s a simple solution to that problem!

I’ve created this glossary to help you through those times when a new word or term holds you up. You’ll find definitions of many of the programming terms used in this book, so look here if you encounter a word that you don’t understand.

animation

The process of displaying a sequence of images fast enough that it looks like something is moving.

block

A group of computer statements in a program.

Boolean

A type of value that can be either true or false. (In Python, it’s True or False, with capital T and F.)
