The prompt is the line you’re currently typing on. Right now, we’re only concerned with the prompt. Some text is printed to say who you are and when you last logged in, but we’ll worry about that later. This is because, by naming the file with a “.py” at the end, you’ve helped Sublime to guess that this is a python file, and it has applied Python language highlighting. Notice how after you save the file, Sublime starts highlighting it, turning the word “print” one color, and the text another color.

Later we will learn how to navigate files at the terminal, but for now, saving to your home directory will allow use to run the program without worrying about where it is located. Save this file to your home directory as “helloworld.py”. You can find it in your Applications folder inside another folder called Utilities. The command line program in OS X is called Terminal.
It is also a good idea to add this program to your dock.

Download the OS X copy, open the dmg file you downloaded, and drag the Sublime icon to your Applications folder. Sublime looks like a simple notepad, but it provides what is called syntax highlighting. Programs are organized text, so showing them in colors helps highlight the important parts: We will use a middleweight program called Sublime Text.

They range from the very light weight (some programmers just use a basic notepad) to the very heavyweight (big development environments like Eclipse and Visual Studio will automatically complete some of your code for you). Microsoft Word and Gmail are text editors, but they have special features which get in the way of writing programs. A text editor is just a program for writing. Since programs are written in text, it’s good to write them in a text editor. Just as there are good places to write documents (Microsoft Word) and emails (Gmail), and good places to edit photos (Photoshop) and draw pictures (Illustrator), there are good places to write programs. The command line is where you’ll run your first few programs. It looks like something used by old school hackers on television: The command line is a program where you type commands and the computer outputs results. So, to start out, most programmers learn to program using the command line. When you’re beginning to learn to program, it’s hard to do all the fancy graphics necessary to make a website or a phone app. Our version will print the words “Hi, Everybody!” onto the screen. The first program we’re going to write in this tutorial is the classic “Hello World”. Programs can do all kinds of stuff, like printing, calculating with numbers, reading a website, or sending a file. When you run a program, you’re giving that text file to Python, and Python is making your computer do stuff. When you write a program, you’re just writing a text file (similar to a word document, or an email, or a short story). Python is one of the most popular programming languages. Programs are recipes you write to make your computer do things. These recipes are written in a programming language, which is a language close enough to human for you to write, and organized enough for a computer to read.
To start, we need to get some things straight. Hello, World! This tutorial will teach you to write and run your first Python program on a Mac.
