In this video, we're going to actually download and install Python 3 from python.org on a Macintosh if your Mackintosh, for years, has wonderfully come with Python 2. So, if I type Python minus minus version, I type that, I see that I'm got Python 2.0. What we want to do is in addition installed Python 3. One of these days, Macintosh might upgrade their distributed version of Python 3, but there's so many things inside Mac that depend on Python 2. I'm going to expect that it will always be named Python 3, which is what we're going to call it in a second. So, here I am at the python.org/downloads, and I'm going to download Python 3, you click here, and I'm actually got it sitting here in Downloads already because I always do that. So, I'm going to install this. There is the installer, we'll say Continue, Continue, Continue. Of course, I agree. I read all that really fast, and now I'm going to install it. Okay. So now, that means if I run a terminal, so this of course, is start run terminal. So, Python 2 is still there, but Python 3 is also now involved there. So, we should have Python 3 installed. So, we install Python 3.6, and so there we go. That's all it takes to install Python 3 on a Macintosh. So, let's write our first little Python program. I'm going to, I like Atom. So, I've got this Atom Editor, it's atom.io. Right here, atom.io, download and install the Atom Editor. I like it because Atom works the same on both Windows, Mac, and Linux, and it has syntax highlighting, so I really like things like that. So, I'm going to make myself a simple Python program. Hello world, like we always do. Now, you'll notice that it's not syntax highlighting yet, but I'm going to do a File, Save As, and I'm going to go into my desktop, and I want to make a folder called py4e. I'm just calling this call as hello.py. Oh, crud got to rename it. Rename it, and put two dots hello.py, there we are. So, now I'm here, and I'm in my home folder, I can go on my desktop, and I can go into that new folder I made Python for everybody, and I can see the files. Now, there are ways to run this. I really want you to learn the terminal so that you really know what you're doing. So, here we are, we're in the folder that has the Python, and then all we do to run it is we say, "python3 hello.py", and there we go. Of course, this is Python 3, because I'm using parentheses there instead of double quotes. But Python two is still there, and of course, if you just run python hello.py, it'll be a syntax error or not. Must be they added something. Yeah. Because Python is still version two, but apparently, they allowed print in the latest version of Python 2. So, away we go. Okay? So again, thanks for watching. I hope this was helpful to you to get Python 3 installed on your Macintosh.
