Installing Python3:24 with Kenneth Love
Eventually you're going to need to use Python outside of Workspaces. In this video, I'll install Python on a Mac and make sure `pip` is available.
The official Python site, where you can download the installer.
If you install Python from the official download, you'll use the command
python3 to run Python and
pip3 to use
(also, wow, I totally called Spotlight "Safari")
[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
