- [Instructor] To follow along with the exercises on a Mac,you'll need the latest version of Python 3,and I recommend the free versionof Active State's Komodo Editor.Here's how to install these components on a Mac.And so first we're going to install Python.Now I've already downloaded the installer to my desktop,but you'll want to download it from here,and you'll want to make sure that you downloadthe version that says Python 3.So this is Python 3.6.3.Whatever version you see will be later than this oneand that's fine.

Do not download Python 2.Python 2 is probably already installed on your Mac,and it's used internally, and soyou'll want to download Python 3and that will run separately and in addition tothe Python 2 and it won't cause any problems on your Mac.I've been doing it for years.So, I've already downloaded the installer hereso I'm just going to minimize Chromeand I'm going to come over here to my desktopand I'm going to double click on the Python package here.

And we'll just press continue and continue and continueuntil we get the agree and press that.You'll notice I read all of that very carefullybecause that's important.And then I press install and type in my passwordand wait for it and once that's done, I press close.And Python is installed. It's as simple as that.We'll test it in a few minutes after we install Komodo.So I'm going to come back out here to my browserand here I've opened activestate.com/komodo-edit.

And there's two versions.There's actually several editionsbut there's two major versions of the Komodo Editor.One of them is called the Komodo IDEand you can tell that they want you to download that onebecause the button is bigger and it's red.And then there's the Komodo Edit which is freeand you're going to want to download the Komodo Edit.You can look at the comparison.If you scroll down here, you can look at the comparisonof the features of Komodo Edit and Komodo IDEand there's quite a lot of features that are in the IDEversion that are not in the free versionand if that's important to you, of course,you're welcome to pay for that and use that.

For my purposes and for following along,if you want your screen to look just like mineas you follow along, you'll want to use the Komodo Editwhich is the free version.The Komodo IDE version, of course it has more features,and it costs about 300 to 400 US dollars for personal use.In this course, we're using the free versionand we just click here on Komodo Editand then on the big download button for Komodo Edit,whatever the latest version is is fine.It changes every year and I haven't seena whole lot of big differences in them as they change.

Again, I've already downloaded this to my desktopand we'll just double-click on the DMG package.And just drag that over into applications.Wait for it to copy, and once that's copied,I can control click and eject the download folder.And you'll see here it is in my applications, Komodo Edit 11and I'm just going to run that.And first you'll see this screen.

So this is the appearance and again,use the default or use whatever works for you.For my purposes, I'm going to try and make thisas readable as possible and I'm going to selectCupertino and for now, I'm going to customize it a littlebit later but for now that'll work and then next.And I leave all these defaults.I like indention to four characters. I don't like tabs.I just leave all of these as the defaults.And again, finish.Now this'll up the Komodo Editor.

I will maximize this if I hold down the option queuewhile I press this I get a plusinstead of that so it doesn't do the full screen modebut it maximizes it.So I've modified this version to makethe interface more readable for the purposes of this video.You should configure your own copy to your own preferences.You can come down here to preferences andyou come over here to color scheme,you'll see you can open a color scheme editor.And it'll give you this little warning and you say yes.And the color scheme editor allows you to selecta different theme and you can actually go in thereand customize exactly how you want this to look.

And I recommend that you do that.I've made all the text really bigand made it so that it works well in this video recordingenvironment but that's not goingto be what works best for you.Now before we go any further, we want tocome back into here in preferencesand there's several ways to open the preferences.You can use that button.You can come up here and selectpreferences from the Komodo menu.Or you can, as I usually do, just press command commaand that works on many, many Mac applications.

And there's a couple of thingsthat we really need to do here.First of all, we need to come down here tointernationalization and I'm going to explain this briefly.Python 3 is fully Unicode compliantand what that means is it uses the Unicode standardfor its character sets and it makes itvery international friendly for international languages.And so because Python is Unicode compliant,we want to make sure that our editoris using Unicode character sets.

So under default editor encoding, if it doesn't alreadysay UTF8, you'll want to select UTF8.And then under language specific,you select this box and find Pythonand you want to do this for both Python and Python 3.It's important to do both of them becausesometimes the editor thinks it's Python 2when it's actually Python 3 soyou need to do it for both of them.Select Python and change this to UTF8and then select Python 3 and change that to UTF8and then make sure that it takes because occasionallyit doesn't and that seems to be fine.

And then you'll want to select okay.And this is really important becauseso in what we're doing, we'll use Unicode characters.Now we're going to open our exercise file.So we come over here to left paneand select the gear and open directory.And I'm going to come out here to desktopand select exercise files and say open.And that'll open the exercise files over here.We don't really need this projects pane at this time.

And now, we're going to open the right side pane.And this may be in a different place herebut you want to open the right side pane and again,your pane may look different.Your toolbox may look different.You'll want this to be, the toolbox will show there,and I'm going to control click in an empty spaceand say add new command.And this is going to give us our commandthat we're going to use for running our scripts.

Notepad For Mac

This is the difference between the editorand the IDE version.The IDE version has ways to run scripts already.We have to create one but it's really, really easyto do here and we only have to do it once anyway.So right here in the command box,we're going to type, and it's very important thatthe spelling and the capitalization and everythingis exact so be very careful andI'm going to do this very slowly here.ENV and a space and then all caps LANGwhich is short for language but just the letters LANGand then the equals sign and then again we're in lowercaseEN which is short for English, underscore,and then capital US and a periodand then all caps UTF dash 8.

And again what this does is it makes Komodowork properly with Unicode characters.And then we're going to put in a spaceand in quote marks, and it's hard for youto see the quote marks 'cause this text is so smallon this screen but that's a double quote,percent, capital F, and a close quote.And again those are double quotes and that's a percent sign.So this is everything that needs to go in this boxand it needs to go exactly like this,and all the spelling and capitalization and punctuationis important and then up here,I'm just going to select thisand make this say run dash R like that.

And that's going to be the title of this command.Now before we're done here, we need to come overto advanced options and in the start in box,you're going to select this little arrow hereand select directory path of fileand it'll put a percent D in thereand that's exactly what you want to be there.And then over to the key binding tab,we're going to create a key bindingso that we can call this up just by pressing a key press.And the new key sequence is shift, command, R.

So you're going to hold down the shift keyand the command key which is the onewith the little clover leaf on it and press R.And in the box, it'll type meta shift R like that.And then you have to press the add button or this doesn'twork and now it should say it under current key sequence.So under command, we have our commandand it looks exactly like that.Under advanced options, we have the percent D there.And under key binding, we have that meta shift R.If all that's correct, you can press the okay buttonand you'll see over here, it shows upin our sidebar, it says run dash Rand we'll test that in a minute.

But for now, we're just going to close that right pane,and we're going to come over here to our chapter 1 filesand open that up and double click on hello dash version.And I'm going to press shift command Rwhich will run it and we'll see down herein the command output at the bottom it says,this is Python version 3.6.3.So this is testing everything.We've installed Python correctly. We've installed Komodo.We've set it up to run our scripts,and now our computer is completely set upto run Python scripts in Komodo Edit.
