windows. 5 00:00:22,790 --> 00:00:30,170 Also, we will need to install PIB envy that will help us to manage Python virtual environments. 6 00:00:30,650 --> 00:00:36,200 Let's get started with the verification of the installation of the python on my ankles, and I'll also 7 00:00:36,200 --> 00:00:38,540 demonstrate you how to update it if needed. 8 00:00:39,230 --> 00:00:45,290 Let's go to the

00:00:50,570 --> 00:00:57,590 And actually, every Mac also comes with installation of the Python out of the box, but I see that 12 00:00:57,890 --> 00:01:05,269 I have not the latest version and latest version I could verify here at the Python dot org website by 13 00:01:05,269 --> 00:01:06,860 going to download section. 14 00:01:07,310 --> 00:01:09,860 And here I'll see the latest version. 15 00:01:10,100 --> 00:01:16,520 At the moment of the recording of this video is 3.9 or two, and I have one of the previous versions 16 00:01:16,700 --> 00:01:17,150 this way. 17 00:01:17,180 --> 00:01:20,240 Let me update current version to the latest one. 18 00:01:20,690 --> 00:01:23,290 Let me click on download Python 3.9. 19 00:01:23,300 --> 00:01:26,510 The two big file will be downloaded. 20 00:01:26,690 --> 00:01:28,280 Let me open it up. 21 00:01:29,860 --> 00:01:30,580 Continue. 22 00:01:32,060 --> 00:01:34,370 Continue to agree. 23 00:01:36,050 --> 00:01:37,880 Cadena

00:01:49,820 --> 00:01:52,520 Let me close it and let me close installer. 27 00:01:53,180 --> 00:01:53,870 Let's move it to. 28 00:01:54,770 --> 00:01:55,580 All right, let me know. 29 00:01:55,580 --> 00:02:02,780 Verify whether a Python 3.9 is available here in the terminal and I still see previous version. 30 00:02:02,990 --> 00:02:07,010 I need to reopen time in order to see a new version. 31 00:02:07,280 --> 00:02:10,740 Let me actually try to open a new tab like that press. 32 00:02:10,759 --> 00:02:15,960 No, I don't want to update on my cell and your type Python three. 33 00:02:15,980 --> 00:02:17,750 Does this version once again? 34 00:02:18,020 --> 00:02:19,100 And now I see it. 35 00:02:19,110 --> 00:02:28,340 Latest version three 9.2 Also, along with Spiderman three, I should see the IP three that is actually 36 00:02:28,340 --> 00:02:30,590 package manager for Python. 37 00:02:30,920 --> 00:02:34,160 And if I type Vibe three, I'll see a bunch of options. 38 00:02:34,370 --> 00:02:41,100 And if I add here does this awesome IOC version of the Play three and it has twenty to 2.3. 39 00:02:41,690 --> 00:02:47,210 It means that I am good to go now and I'm able to use latest version of the Python on this computer 40 00:02:47,510 --> 00:02:49,520 and also accept the Python. 41 00:02:49,730 --> 00:02:58,100 And I need the additional package installed to scold baby envy, and I could verify whether it didn't 42 00:02:58,100 --> 00:03:00,420 start honored by typing vibe. 43 00:03:01,190 --> 00:03:05,000 There's desperation and I see that the command is not found. 44 00:03:05,480 --> 00:03:11,870 No, let's install this additional package globally on this computer, and with this package, baby 45 00:03:11,870 --> 00:03:18,320 in we, we will be able to create Python virtual environments after installation in one of the next 46 00:03:18,320 --> 00:03:18,830 lectures. 47 00:03:19,010 --> 00:03:25,700 I'll explain you why I recommend you to use baby envy for managing Python beautiful moments. 48 00:03:25,700 --> 00:03:30,770 And also, I'll explain what is Python virtual environment for now? 49 00:03:30,770 --> 00:03:33,980 Let's just install this baby in the package. 50 00:03:34,310 --> 00:03:41,060 For that, let's go to Google Chrome Feuilles and here it is in your tab lets type the IBM Ian VM. 51 00:03:42,170 --> 00:03:50,990 And let's click on the link that leads us to buy buy dot org website that the least all available Python 52 00:03:50,990 --> 00:03:51,710 packages. 53 00:03:52,220 --> 00:03:59,480 And here you'll find the sweeps of the Envy package, and you might tweet here that this package automatically 54 00:03:59,480 --> 00:04:04,040 creates and manages virtual environments for your Python projects. 55 00:04:04,580 --> 00:04:12,410 It released all packages in the AP file and also it will generate a B file log file. 56 00:04:13,010 --> 00:04:13,420 All right. 57 00:04:13,620 --> 00:04:17,029 Let's go ahead and install the HP Envy for Mac. 58 00:04:17,510 --> 00:04:24,440 And as any Python package, we could install it with help of pipe that is Python package manager. 59 00:04:24,650 --> 00:04:31,880 If you scroll down to the documentation link here and click on it, you will find actually instructions 60 00:04:32,030 --> 00:04:39,020 how to install the app envy and you'll find three options here with help of you. 61 00:04:39,410 --> 00:04:45,170 Actually, you should use Baby three, the this package installer for the third version of the Python, 62 00:04:45,770 --> 00:04:50,810 and also there was alternative commands to install a PTEN VM. 63 00:04:51,170 --> 00:04:56,810 But as you might read here, this option is now discouraged and you should not use it. 64 00:04:57,080 --> 00:04:59,510 So please use this command instead. 65 00:05:00,110 --> 00:05:08,450 Let's go ahead and using Tap Package Manager, install and weep for a particular user in its home directory. 66 00:05:09,020 --> 00:05:17,570 Let's go to the terminal and here again, instead of B.A.P, please type tap three, then install Yeoville 67 00:05:17,780 --> 00:05:22,880 option does this user and next will be the name of the package baby NBA. 68 00:05:23,420 --> 00:05:24,950 Let's go ahead and install it. 69 00:05:27,980 --> 00:05:35,440 Installation was completed, but I see few warnings, and the first one is here aren't the scripts ABC, 70 00:05:35,540 --> 00:05:40,880 NBC and ABC envy this resolver are installed in this folder. 71 00:05:41,060 --> 00:05:44,990 Here it is, but this folder is not in power. 72 00:05:45,950 --> 00:05:50,840 You might see also all the warnings related to all those sweeps that were just installed. 73 00:05:51,840 --> 00:05:58,500 We'll dispel wealth is an environment variable, and it is a global environment variable Olmec, and 74 00:05:58,500 --> 00:06:04,500 you could read any variable on Mac by entering the comment Echo Dot or sign variable. 75 00:06:05,100 --> 00:06:11,940 And if you type this comment, you'll see current value of this environment variable path. 76 00:06:12,930 --> 00:06:17,760 And you might notice that this folder not in this path. 77 00:06:18,390 --> 00:06:27,030 That's why I will be able to access any script located in this folder globally inside of the command 78 00:06:27,030 --> 00:06:31,320 line by simply entering, for example, envy. 79 00:06:31,980 --> 00:06:40,590 If I enter such command, I'll see error from the Z Shell Shell command not found by any of you. 80 00:06:41,130 --> 00:06:44,010 And this what this warning is all about. 81 00:06:44,670 --> 00:06:53,430 We need to modify path and add this folder to it, and we could do that either temporarily by using 82 00:06:53,460 --> 00:06:57,570 export command here or directly in the terminal or permanently. 83 00:06:57,990 --> 00:07:03,120 If you want to go to the permanently, you need to modify this shell configuration profile. 84 00:07:03,870 --> 00:07:10,740 Please notice that Z Shell is default shell in Catalina and older versions of the macOS. 85 00:07:11,710 --> 00:07:17,830 In previous versions, if you're using older versions, you need to modify best profile instead of Z 86 00:07:17,850 --> 00:07:18,730 cell profile. 87 00:07:19,450 --> 00:07:24,760 Now let me show you how to modify his usual profile on this computer in order to do that. 88 00:07:24,790 --> 00:07:27,750 Please go to a home directory of your user. 89 00:07:28,450 --> 00:07:31,900 I am actually already in the home directory of this user. 90 00:07:32,140 --> 00:07:37,560 This deal, the sign tells me that, but if you are not in the home directory, you could send it to 91 00:07:37,600 --> 00:07:40,360 it by entering Sydney and do the sign like that. 92 00:07:40,870 --> 00:07:44,200 And here a police type alerts this L.A. command. 93 00:07:44,740 --> 00:07:49,780 This command will lease the old files and folders in the home directory of the user. 94 00:07:49,870 --> 00:07:58,390 In my case, this Bogdan user and you should find your hidden file gold dot z cell rc and we need to 95 00:07:58,390 --> 00:08:05,920 modify exactly this file in order to be able to access executable files inside of this folder. 96 00:08:06,140 --> 00:08:09,310 Looking at scroll a bit up inside of this folder. 97 00:08:09,970 --> 00:08:12,700 Let me copy this folder name like that. 98 00:08:13,000 --> 00:08:15,190 Please do so as well on your computer. 99 00:08:15,460 --> 00:08:20,320 You, of course, see another path because your user will be different from mine. 100 00:08:20,470 --> 00:08:21,730 Please copy your path. 101 00:08:22,570 --> 00:08:30,310 Next, let's edit DOT is you sell RC file, and you can do that very easily using content editor that 102 00:08:30,310 --> 00:08:31,600 is built in on Mac. 103 00:08:31,930 --> 00:08:34,490 Simply type now and name of the file. 104 00:08:34,510 --> 00:08:36,220 Dot Z Cell RC. 105 00:08:36,250 --> 00:08:42,880 Like that and you'll find existing configuration file for Z Cell on the second line. 106 00:08:42,909 --> 00:08:45,790 You should see such as export path. 107 00:08:46,390 --> 00:08:53,890 In my case, it is comment that out here, I see this pound sign if in your case, it is not coming 108 00:08:54,100 --> 00:08:54,490 out. 109 00:08:54,700 --> 00:09:02,800 You should modify your export path command and add to it folder that you just copied from the warning. 110 00:09:09,890 --> 00:09:12,830 I will throw uncomment this line like that. 111 00:09:13,550 --> 00:09:16,240 And afterwards, bliss, modify it like that. 112 00:09:16,910 --> 00:09:23,390 Remove this section from hero worship only door sign, pile and paste here. 113 00:09:23,660 --> 00:09:27,830 Go a bit path to the folder that we just copied from as a warning. 114 00:09:28,310 --> 00:09:31,970 And next, please ED column before the assigned path. 115 00:09:32,660 --> 00:09:39,410 This will mean that this command will actually modify existing agbele of the path environment variable 116 00:09:39,800 --> 00:09:42,860 and and to eat this string. 117 00:09:43,890 --> 00:09:51,690 If in your case, in that Z Cell C configuration file, you already see uncommon that export path line. 118 00:09:52,380 --> 00:09:58,050 Please don't delete anything in it and just add prefix to it like this. 119 00:09:59,590 --> 00:10:05,440 No, let's say who changes in this configuration file for that police rescue combination of control. 120 00:10:06,310 --> 00:10:09,040 Then press yes and press enter. 121 00:10:09,940 --> 00:10:16,750 Now you could verify whether changes were applied or not by entering court Dot Z Cell are C command 122 00:10:17,440 --> 00:10:20,500 and scroll up to the very beginning of this file. 123 00:10:20,980 --> 00:10:25,930 And here you should find command export path that looks like this. 124 00:10:26,500 --> 00:10:26,890 All right. 125 00:10:27,250 --> 00:10:32,500 Now all is said and we could try to a law terminal in order to verify wells. 126 00:10:32,650 --> 00:10:36,760 Now we will access EMV executable file. 127 00:10:37,090 --> 00:10:40,510 But before doing that, let me quickly deal a wheels. 128 00:10:40,600 --> 00:10:44,920 One more warning I saw here during installation of the interview. 129 00:10:45,250 --> 00:10:46,690 And here was this warning. 130 00:10:47,110 --> 00:10:54,360 I was told that the paper version is older than last version, and I could very easily update version 131 00:10:54,370 --> 00:10:57,400 of the baby by entering such comment. 132 00:10:57,880 --> 00:11:02,440 I could copy it from a show like that and paste it here and execute. 133 00:11:03,970 --> 00:11:06,070 Babies should be updated right now. 134 00:11:06,880 --> 00:11:12,730 And now the AP abortion 21 does 0.1, in my case was successfully installed. 135 00:11:13,330 --> 00:11:15,880 No, let's go ahead and reload terminal. 136 00:11:16,000 --> 00:11:18,370 In my case, I'm using Item two. 137 00:11:18,580 --> 00:11:25,480 You could probably use terminal application that is built in terminal on calls, but before load of 138 00:11:25,480 --> 00:11:31,660 the terminal, let me go to this four step where I'm still running front and application and terminate 139 00:11:31,660 --> 00:11:33,550 this process by pressing control. 140 00:11:33,580 --> 00:11:34,870 C key combination. 141 00:11:35,290 --> 00:11:39,670 And no lets exit from Item two with terminal. 142 00:11:39,970 --> 00:11:42,400 And now let's open it back again. 143 00:11:44,360 --> 00:11:52,340 And here, let's verify current value of the path variable like that, and I'll see that it was correctly 144 00:11:52,340 --> 00:12:01,340 adjusted as was instructed in the Dot Z cell are a C configuration file and this folder is here in the 145 00:12:01,340 --> 00:12:01,640 path. 146 00:12:02,330 --> 00:12:02,720 Go ahead. 147 00:12:03,110 --> 00:12:10,940 It means that the now I could try to access B.A.P Envy executable file and view and type, for example, 148 00:12:10,940 --> 00:12:12,350 option does this bottom. 149 00:12:13,310 --> 00:12:21,440 And now I see resolved version of the PPE and we installed on this computer is here and now I have access 150 00:12:21,440 --> 00:12:23,870 to the IPAB and executable file. 151 00:12:24,650 --> 00:12:31,480 This concludes installation of all Python tools necessary for development of API service and then the 152 00:12:31,480 --> 00:12:32,210 next lecture. 153 00:12:32,210 --> 00:12:34,580 I'll explain you how to do the same on windows. 154 00:12:34,700 --> 00:12:37,120 How to install Python and API envy. 155 00:12:37,130 --> 00:12:39,860 There are if you are a macOS user, of course. 156 00:12:39,860 --> 00:12:41,930 Feel free to skip next show. 157 00:12:42,140 --> 00:12:43,010 I'll see you soon.
