1 00:00:05,300 --> 00:00:11,120 Welcome back, everyone, in this lecture, we're going to discuss installing packages by installing 2 00:00:11,120 --> 00:00:16,790 Python, either from Python dot org or through Visual Studio code or through the Anaconda distribution. 3 00:00:17,060 --> 00:00:19,730 You've already also installed what's known as PIP. 4 00:00:20,180 --> 00:00:25,400 PIP is a simple way to download packages at your command line directly from the Papy repository. 5 00:00:26,710 --> 00:00:30,040 There are packages already created for almost any case you can think of. 6 00:00:30,490 --> 00:00:35,080 A quick Google search will usually help you discover a link to the paper page for the package or for 7 00:00:35,080 --> 00:00:36,280 the package documentation. 8 00:00:36,790 --> 00:00:42,520 For example, if you're looking for a package to help you out with Excel, you could Google search Python 9 00:00:42,520 --> 00:00:48,160 Excel package and you'll get several packages and links that you may find useful along with the documentation 10 00:00:48,160 --> 00:00:48,640 pages. 11 00:00:49,690 --> 00:00:53,650 So we're going to do is just quickly show you how to download and install external packages. 12 00:00:54,160 --> 00:00:56,620 This is all going to be done at the command prompt or command line. 13 00:00:56,950 --> 00:00:59,470 If you're on mucosal Linux, this will be done at the terminal. 14 00:00:59,710 --> 00:01:04,510 We're just going to do this at the command line inside a visual studio code, and we'll install the 15 00:01:04,510 --> 00:01:07,240 Django package because we'll be using that in the next section. 16 00:01:07,420 --> 00:01:08,110 Let's check it out. 17 00:01:08,350 --> 00:01:08,590 All right. 18 00:01:08,590 --> 00:01:10,570 So here I am inside a visual studio code. 19 00:01:10,840 --> 00:01:15,580 Before we jump to how to actually do this at the command line, I do want to point out the typical workflow 20 00:01:15,580 --> 00:01:17,350 for figuring out how to install a package. 21 00:01:17,770 --> 00:01:23,500 And what you can do is just do a Google search for Python Plus, either the topic you're looking for 22 00:01:23,530 --> 00:01:25,240 or the specific package name. 23 00:01:25,570 --> 00:01:31,150 So here I'm doing a Google search for Python, Django and pretty much you'll find the either link, 24 00:01:31,330 --> 00:01:37,180 which is the repository that's holding everything to install from or the actual documentation online 25 00:01:37,180 --> 00:01:37,600 page. 26 00:01:37,600 --> 00:01:40,870 So we can go to Django will say, OK, download. 27 00:01:41,170 --> 00:01:42,720 So now I'm Django Project. 28 00:01:42,720 --> 00:01:44,050 Com Forward slash download. 29 00:01:44,380 --> 00:01:48,550 And here you can actually see how to get the official version, which is just pip. 30 00:01:48,550 --> 00:01:49,540 Install Django. 31 00:01:49,810 --> 00:01:56,140 And if you want a specific version of a package library, you can put equals equals and then the actual 32 00:01:56,140 --> 00:01:56,980 version you want. 33 00:01:57,370 --> 00:02:02,170 So maybe you're actually looking to install Django version three point zero, for instance, you would 34 00:02:02,170 --> 00:02:04,990 say PIP install Django equals equals three point zero. 35 00:02:05,350 --> 00:02:10,000 If you just want to install the most up to date latest official version, you should also be able to 36 00:02:10,000 --> 00:02:12,040 say PIP install Django. 37 00:02:12,430 --> 00:02:16,080 Now there's technically also the ability to get the latest development version. 38 00:02:16,390 --> 00:02:21,190 I would not recommend this because this is actually going straight to GitHub and grabbing the absolute 39 00:02:21,220 --> 00:02:24,970 latest, which is technically not associated with any particular version number. 40 00:02:25,210 --> 00:02:30,340 So this is going to be trickier to develop on because this is constantly changing either day to day 41 00:02:30,340 --> 00:02:31,630 or week to week or month to month. 42 00:02:31,840 --> 00:02:35,890 So typically, you're going to want to stick with at least some sort of numbered version. 43 00:02:36,280 --> 00:02:39,250 In fact, let's go ahead and pip install Django for right now. 44 00:02:40,440 --> 00:02:47,460 So I can come here to my command line and say, PIP, install Django, and even just doing this should 45 00:02:47,460 --> 00:02:48,900 actually install the latest version. 46 00:02:49,350 --> 00:02:54,990 If you're looking to install specifically Django for we can say PIP Install Django equals equals 4.0 47 00:02:55,950 --> 00:02:56,420 Enter. 48 00:02:56,760 --> 00:02:58,110 And technically 4.0. 49 00:02:58,500 --> 00:03:03,210 Now you'll notice when I run this, it already says requirement already satisfy for me because I've 50 00:03:03,210 --> 00:03:05,950 already installed Django myself for you. 51 00:03:05,970 --> 00:03:08,760 You may get a prompt that either says yes or no. 52 00:03:09,480 --> 00:03:14,250 Now I want to show you just another quick example of maybe installing a package you find useful. 53 00:03:14,730 --> 00:03:15,870 So what can you do? 54 00:03:16,110 --> 00:03:20,400 Well, you can just search for something like, OK, I want to use Python with Excel. 55 00:03:20,790 --> 00:03:25,740 So you would Google search Python Excel and then you would start getting links here on guides, which 56 00:03:25,740 --> 00:03:29,010 are also going to show you different options for packages. 57 00:03:29,430 --> 00:03:32,490 So maybe we want to actually download Open Excel? 58 00:03:32,820 --> 00:03:36,360 You can check out the documentation or the actual download link. 59 00:03:36,810 --> 00:03:42,870 So each of these packages is being hosted on paper, which you can visit pipefitter or it'll give you 60 00:03:42,870 --> 00:03:43,840 the description. 61 00:03:44,250 --> 00:03:47,630 Some example code, a documentation link, et cetera. 62 00:03:48,030 --> 00:03:53,070 And if you just click on this documentation link here on Read the docs, typically they're going to 63 00:03:53,070 --> 00:03:59,190 have some sort of instruction on how to actually install this, or what you often do is just check out 64 00:03:59,190 --> 00:04:00,060 the installation page. 65 00:04:00,300 --> 00:04:05,370 You'll notice it's actually kind of small here, but you just type out pip install open pixel. 66 00:04:05,700 --> 00:04:09,210 This is just a random example of something you may want to do if you don't find yourself working in 67 00:04:09,210 --> 00:04:10,920 Excel, and we won't in this course. 68 00:04:11,130 --> 00:04:14,910 You may not need to install something like that, but just want to show you how easy it is to run these 69 00:04:14,910 --> 00:04:19,050 sort of commands and just do a Google search for the packages or libraries you're looking for. 70 00:04:19,589 --> 00:04:21,000 All right, that's it for this lecture. 71 00:04:21,029 --> 00:04:21,839 I'll see it the next one.
