Background

A teletype machine (or teleprinter) is an electromechanical device which can be used to send and received typed messages over a distance. It was one of the first devices which enabled the layman, not trained in Morse Code, to communicate easily with another.

Introduction

The print function is one of the most basic functions available and is also one of the most useful. It provides us with the ability to easily output data from our program, most often to the console. As such, it is invaluable for both a completed programming and for assisting us to debug a program during development.

Basic Usage

In its most basic form, the print function takes a single argument. It's able to print integers, floating points, Booleans, and strings.
