[spam][draft] Hello World

Hello World is a very basic introductory computer program that demonstrates how to call a function. A function is like a tool. In fact, it should be called a "tool" rather than a "function" because then people would save memory space for things that introduce new meaning. Here is a hello world application in python: print("Hello, world.") It's a single line of text. The tool (or function) being used is "print". Print is a tool for outputing text. When used, it outputs text. Like most tools, it needs something to be used on. We give it the text: "Hello, world." .In python, text that's going to be used with tools like "print" needs to be surrounded by double quotes.
