1 00:00:01,670 --> 00:00:05,690 OK, in this video, we're going to create a directory to hold all the files we're going to be creating 2 00:00:05,690 --> 00:00:08,880 throughout this course, and we'll also spin up a virtual environment. 3 00:00:08,900 --> 00:00:10,850 I'll tell you what that's all about as well. 4 00:00:10,860 --> 00:00:12,440 So open up your get back terminal. 5 00:00:12,830 --> 00:00:15,070 And again, this will say something different. 6 00:00:15,080 --> 00:00:15,890 No big deal. 7 00:00:16,160 --> 00:00:18,140 Whatever it says, there doesn't matter at all. 8 00:00:18,350 --> 00:00:22,820 The first thing we need to do is create a directory where we want to save all of our files going forward 9 00:00:22,820 --> 00:00:23,350 in the course. 10 00:00:23,660 --> 00:00:30,140 So to do that, you type in Mark Dya stands for Make Directory and you can put this anywhere. 11 00:00:30,140 --> 00:00:35,960 I want to put it in my C drive and let's call this, I don't know, goosies graphical user interfaces. 12 00:00:36,320 --> 00:00:37,640 I don't know, call it anything you want. 13 00:00:37,970 --> 00:00:41,240 I go and click that now we need to move into that directory. 14 00:00:41,450 --> 00:00:47,450 So we use the CD command that stands for Change Directory and then just type in whatever that was that 15 00:00:47,450 --> 00:00:48,230 you just created. 16 00:00:48,530 --> 00:00:49,640 And you'll see right here. 17 00:00:50,540 --> 00:00:51,170 There it is. 18 00:00:51,650 --> 00:00:54,680 And we can type in the command to show us where we are. 19 00:00:54,680 --> 00:01:00,380 And sure enough, we're in the c e directory for you type that ls command to list the stuff in this 20 00:01:00,380 --> 00:01:00,800 directory. 21 00:01:00,800 --> 00:01:05,240 And there's nothing listed because there's we haven't created a created anything yet and we're going 22 00:01:05,250 --> 00:01:05,570 to go. 23 00:01:05,590 --> 00:01:07,280 So go ahead and clear the screen now. 24 00:01:07,550 --> 00:01:09,140 I'm going to create a virtual environment. 25 00:01:09,350 --> 00:01:11,430 You don't strictly speaking, have to do this. 26 00:01:11,430 --> 00:01:13,400 So if you want to skip this step, you can. 27 00:01:13,760 --> 00:01:19,100 But any time I'm coding anything in Python, I like to create a virtual environment in a virtual environment 28 00:01:19,100 --> 00:01:20,720 is like a little walled garden. 29 00:01:20,960 --> 00:01:26,720 It allows us to do stuff inside the virtual environment that then doesn't affect the rest of our computer 30 00:01:26,720 --> 00:01:32,330 so we can install different modules and different versions of things inside our virtual environment 31 00:01:32,780 --> 00:01:35,690 and then it doesn't affect the rest of the computer. 32 00:01:35,690 --> 00:01:43,160 So if, for instance, we need to download and install a certain version of a module or something, 33 00:01:43,280 --> 00:01:47,240 we can do that inside the virtual environment, even though we might have a different version of that 34 00:01:47,240 --> 00:01:49,130 thing installed somewhere else on our computer. 35 00:01:49,130 --> 00:01:52,970 So it's just a sort of a best practice when it comes to programming in Python. 36 00:01:52,970 --> 00:01:53,840 So I always do it. 37 00:01:54,800 --> 00:01:59,270 We're not going to be installing a lot of things with it throughout this course, maybe one or two little 38 00:01:59,270 --> 00:02:00,260 things here and there. 39 00:02:00,770 --> 00:02:03,440 So it's not super important, but we just do it. 40 00:02:03,440 --> 00:02:04,880 It takes a second, so we might as well. 41 00:02:04,880 --> 00:02:11,600 So to do this, we just type in Python, dash em and then V N.V. we're going to create a virtual environment. 42 00:02:11,600 --> 00:02:13,640 V and V stands for virtual environment. 43 00:02:13,880 --> 00:02:17,450 And now we just want to name this and I'm just going to call it Virt for Virtual. 44 00:02:18,080 --> 00:02:20,210 And it takes a second to spin this up. 45 00:02:21,380 --> 00:02:24,300 And install some files and boom, it's done. 46 00:02:24,320 --> 00:02:29,270 Now, if we type the command to list the stuff in this directory, we see there's this new virt directory 47 00:02:29,480 --> 00:02:33,470 and inside it there, there's all kinds of stuff that will create a virtual environment for us. 48 00:02:33,480 --> 00:02:35,210 So we've got all the things we need now. 49 00:02:35,210 --> 00:02:36,440 We just need to turn it on. 50 00:02:36,650 --> 00:02:43,460 And to do that, we type in source and then virt and then scripts capital s and then activate. 51 00:02:43,730 --> 00:02:49,340 And when we do, you'll notice this virt in parentheses above our command prompt. 52 00:02:49,700 --> 00:02:52,330 That means our virtual environment has been turned on. 53 00:02:52,670 --> 00:02:55,640 So now we can do stuff in this directory. 54 00:02:56,570 --> 00:02:59,610 And install different things if we want to. 55 00:02:59,630 --> 00:03:02,750 There's nothing we need to install right now, but that's cool. 56 00:03:02,750 --> 00:03:07,280 So so if you want to turn off your virtual environment, you can type the command deactivate. 57 00:03:08,840 --> 00:03:15,170 Like that, and then you see now there's no little overt thing above our command terminal or command 58 00:03:15,170 --> 00:03:16,940 prompt there, so I mean, it's been turned off. 59 00:03:17,120 --> 00:03:18,010 So let's turn it back on. 60 00:03:18,020 --> 00:03:21,050 I'm just going to hit my up arrow a few times to kind of. 61 00:03:21,940 --> 00:03:27,970 Cycle through my last commands, and again, there's the command source, virt scripts activate and 62 00:03:27,970 --> 00:03:30,600 boom, now our little thing has has been turned on. 63 00:03:30,610 --> 00:03:36,100 Now, if you're on a Mac or a Linux, I think the command to start your virtual environment is source 64 00:03:36,250 --> 00:03:37,630 Behn activate. 65 00:03:40,250 --> 00:03:45,110 I'm pretty sure if that doesn't work, you just have to Google, you know, Vermaak and it'll show you, 66 00:03:45,110 --> 00:03:47,890 but I'm like ninety five percent positive. 67 00:03:47,900 --> 00:03:50,960 That's the command to turn on your virtual environment for Mac or Linux. 68 00:03:51,290 --> 00:03:52,570 OK, so now we're ready to go. 69 00:03:52,580 --> 00:03:53,900 We've got everything installed. 70 00:03:54,110 --> 00:03:59,930 We've got our little directory created and the only thing left to do now is to start to create our first 71 00:03:59,930 --> 00:04:00,920 counter project. 72 00:04:01,190 --> 00:04:01,650 So. 73 00:04:01,650 --> 00:04:03,290 Well, I think we'll do that in the next video.
