Installing Python

[SOUND] As far as Tree House is concerned we've been able to do pretty 0:00 much everything in work spaces it's such a handy tool. 0:06 But you won't be able to use work spaces for the code you write at a job and 0:11 you don't always have the internet available. 0:14 To fix both of these issues we should get Python setup on your own computer. 0:16 In this workshop we'll install Python 3 on a Macintosh computer, and 0:21 make sure pip works so that we can install 3rd party libraries. 0:24 I think that's enough talking, let's get to the doing. 0:27 So we start with going to python.org as you can see I've already done. 0:31 Python.org is actually a really great site. 0:35 You should totally be using this site all the time anyway, mainly for 0:38 this documentation tab. 0:41 But we're gonna go here to the downloads tab. 0:43 When I hover over this, I can download for Mac OS X. 0:47 If you're on Treehouse using Workspaces, you've seen either Python 3.4 or 0:50 some of the newer stuff as Python 3.5. 0:55 The current download here is Python 3.5. 0:57 Yeah, the versions are different, but so long as that 3 is in there and 1:00 it's greater than a 3.3 should be just fine. 1:04 If anything does come up as being broken, then I'll update this video, 1:07 I'll let everybody know on the community, and we'll all be good. 1:13 So I'm gonna click 3.5 to download the .dmg and 1:17 I'm gonna let it just download here for a minute. 1:21 So when this finishes downloading, which it's got about a second left here, I'm 1:25 gonna go ahead and click that so that it will open the dmg and run the installer. 1:30 And so here's the installer. 1:35 And we're gonna say Continue. 1:36 If you get a download, a dmg and you're trying to run it straight from that dmg, 1:38 there's a chance this won't run because it's not signed. 1:41 If it's not signed, just right-click on it, choose Open and 1:45 then it'll run with no problems. 1:49 So we're gonna go ahead and we're gonna say Continue, 1:51 and we're gonna say Continue, and we're going to Agree. 1:53 Read through all that stuff, of course, if you want. 1:58 Now, I don't need to change anything on Customize. 2:00 But you shouldn't need to either. 2:04 So we hit Install, we type in our password, 2:06 and we just let it run through its thing. 2:14 So yeah, you're good now, right? 2:17 So let's let this finish up, and then we're gonna open up a terminal window. 2:21 And we're going to hit close, and I'm going to pull up Safari and 2:25 open up terminal. 2:29 All right, so here I am in terminal. 2:32 In the Mac version, if I run Python, 2:35 I get the default Python that's on my computer, and I don't want that. 2:39 I want Python 3, which that gives me my 3.5.0. 2:44 So along that same line, if I do pip, 2:51 let's do pip --version here, then you see that this comes from. 2:53 Well, actually it comes from a thing I installed. 2:58 If we do pip3 though, then you'll see that gives us our 3.51. 3:01 This is what we want to use. 3:07 We want to use pip3 if we're on the Mac, so easy enough. 3:08 Right now, 3:12 I have basically the exact same thing on my local machine as I have on workspaces. 3:13 So I can write code just like I did in workspaces. 3:19 Pull up a text editor, write some code, run it in the terminal. 3:21
