1 00:00:00,240 --> 00:00:06,780 In this lesson we will go through the steps to set up Python development environment on your Mac. 2 00:00:06,780 --> 00:00:12,360 If you are using a Windows computer skip the video and go on to the next video which is dedicated for 3 00:00:12,360 --> 00:00:14,450 Windows setup. 4 00:00:14,520 --> 00:00:21,010 We will be installing these four items on the screen if you already have them installed on your computer. 5 00:00:21,030 --> 00:00:23,430 You can also skip this video. 6 00:00:23,580 --> 00:00:30,230 We will start installing X code through Python 3 and parts Ahmadi. 7 00:00:30,420 --> 00:00:37,050 As I mentioned in the beginning if you prefer a different idea E which is not pi term that is okay. 8 00:00:37,500 --> 00:00:40,620 Now let's start by installing X code. 9 00:00:41,070 --> 00:00:51,040 Go to the App Store search for X code using the search bar you will find the X code app on the top. 10 00:00:51,040 --> 00:00:58,630 Since I have already downloaded the app on my computer this button says open in your screen it should 11 00:00:58,630 --> 00:01:04,890 say get like this button click on the Get button to start downloading the app. 12 00:01:04,960 --> 00:01:10,250 Once you start downloading it may take up to an hour depending on your computer. 13 00:01:10,450 --> 00:01:13,200 You will be able to know if you've finished downloading. 14 00:01:13,210 --> 00:01:20,830 Once the button turns to open once you complete downloading click on the open button you will see an 15 00:01:20,830 --> 00:01:25,150 agreement pop up click on agree to continue. 16 00:01:25,150 --> 00:01:27,100 You might be asked for your password. 17 00:01:27,310 --> 00:01:30,820 So enter your Mac password and click on enter. 18 00:01:31,150 --> 00:01:33,820 Then stalling process will begin. 19 00:01:33,820 --> 00:01:35,160 This may take some time. 20 00:01:35,170 --> 00:01:38,970 So skip to the screen after the process is finished. 21 00:01:39,130 --> 00:01:44,380 Once you've finished installing the X code app the screen should be like this. 22 00:01:44,770 --> 00:01:49,270 Since we won't be developing with X code we can close the app store. 23 00:01:49,530 --> 00:01:56,010 Also go to the left top corner and click on X code choose quit X code on the bottom. 24 00:01:56,030 --> 00:01:58,420 Text. 25 00:01:58,530 --> 00:02:01,540 Next we will be installing homebrew. 26 00:02:01,800 --> 00:02:09,970 Open your web browser and go to H2 T.P. colon slash slash brew dot S H. 27 00:02:10,020 --> 00:02:14,310 Once you go to the site you will see a command in the middle of the screen. 28 00:02:14,370 --> 00:02:17,780 Copy the command and minimize the screen. 29 00:02:17,850 --> 00:02:20,880 Next we need to open up a terminal. 30 00:02:20,880 --> 00:02:28,140 Go to the file and click on new finder window click on applications and scroll down to find utilities 31 00:02:30,770 --> 00:02:31,640 and utilities. 32 00:02:31,640 --> 00:02:37,880 You will be able to find terminal once you click on terminal you will see a window pop up like this 33 00:02:38,870 --> 00:02:40,370 for a shorter access. 34 00:02:40,370 --> 00:02:45,220 I advise you to set this terminal and the shortcuts in the terminal. 35 00:02:45,220 --> 00:02:50,210 We will paste the command which we copied earlier then press enter. 36 00:02:50,830 --> 00:02:57,010 You will receive a message asking you to press the return key you press the return. 37 00:02:57,010 --> 00:03:03,420 Now we'll ask you to enter your Mac password once you typed the password and press the return key again. 38 00:03:03,460 --> 00:03:07,010 The Homebrew will start to install. 39 00:03:07,110 --> 00:03:08,910 This may also take some time. 40 00:03:09,120 --> 00:03:15,110 So I'll skip to the screen after the installing has finished you will see that the installation has 41 00:03:15,110 --> 00:03:24,090 finished closed the terminal and will go onto installing Python 3 hoping your web browser and go to 42 00:03:24,090 --> 00:03:26,040 HD TTP Colin. 43 00:03:26,040 --> 00:03:29,740 Slash slash w w w dot python. 44 00:03:29,760 --> 00:03:37,730 Dot org click on the download tab and press the yellow button that says download Python three point 45 00:03:37,730 --> 00:03:39,390 seven point two. 46 00:03:39,590 --> 00:03:46,440 Your computer will start the process in this lesson we are downloading from the official Web site. 47 00:03:46,510 --> 00:03:52,330 If you have previously downloaded python from a different source like Anaconda and the python version 48 00:03:52,330 --> 00:03:58,750 is close to Python three point seven That will also work for you once you've downloaded the package. 49 00:03:58,760 --> 00:04:01,670 You can click on it to launch the installer. 50 00:04:01,880 --> 00:04:04,120 Let's minimize the browsers so you can see better. 51 00:04:05,120 --> 00:04:09,310 Once then solar is launched go on pressing the continue button. 52 00:04:09,650 --> 00:04:17,200 You will be asked to agree on the licence so he'd agree and continue finally you will see the install 53 00:04:17,200 --> 00:04:17,590 button. 54 00:04:17,590 --> 00:04:18,470 So click on it. 55 00:04:19,660 --> 00:04:26,570 In my case I've set a fingerprint authentication so when installing something this window pops up. 56 00:04:26,620 --> 00:04:30,600 If you don't have it set you will be starting the installation right away. 57 00:04:31,580 --> 00:04:36,140 Once you've finished installation you can close this window. 58 00:04:36,140 --> 00:04:43,170 You wouldn't be needing the installer anymore so you can choose to move it to trash next we want to 59 00:04:43,170 --> 00:04:46,680 check if python has been installed properly. 60 00:04:46,680 --> 00:04:54,860 Let's open the terminal again in the terminal type in Python 3 and press return if python three point 61 00:04:54,860 --> 00:04:56,840 seven point two comes up. 62 00:04:56,840 --> 00:05:00,260 This means installation was successfully done. 63 00:05:00,260 --> 00:05:03,910 Here we've started a shell so you can press control D. 64 00:05:03,920 --> 00:05:13,480 To exit to check where Python 3 has been installed you can type in which Python 3 and press return you 65 00:05:13,480 --> 00:05:16,840 will see which library it's installed. 66 00:05:16,930 --> 00:05:23,180 Now let's go onto installing Python IDC in this lesson we will be installing pi charm. 67 00:05:23,200 --> 00:05:28,680 Idc if you prefer using a different IDC you can do so. 68 00:05:28,750 --> 00:05:32,790 Another great option will be the Visual Studio code idc. 69 00:05:33,010 --> 00:05:38,150 This is free and you can use multiple programming languages like Python and go. 70 00:05:38,800 --> 00:05:45,130 It's becoming one of the best IDC that is out there in the market for free so you can consider using 71 00:05:45,130 --> 00:05:47,230 this idea as well. 72 00:05:47,250 --> 00:05:52,960 Some say that the setup process is a bit confusing in my lessons. 73 00:05:52,960 --> 00:05:58,360 I'll be using pi term since it's easy to set up and the visual is easy to understand which makes it 74 00:05:58,360 --> 00:06:00,220 best for teaching. 75 00:06:00,220 --> 00:06:04,320 But as I said you can choose any I.D. you prefer. 76 00:06:04,690 --> 00:06:13,130 If you choose to use pi term you can hit the download button here pi charm has two types of options. 77 00:06:13,270 --> 00:06:15,950 The professional will cost you the license fee. 78 00:06:16,270 --> 00:06:19,310 You see that the fee is one ninety nine per year. 79 00:06:19,480 --> 00:06:24,460 If you wouldn't be using a lot of features you can stick to the community virgin. 80 00:06:24,460 --> 00:06:27,880 I will be using the professional version in this lesson. 81 00:06:27,880 --> 00:06:33,490 There may be a slight difference in the layout if you will be using the community version but I don't 82 00:06:33,490 --> 00:06:35,350 think it will bother you too much. 83 00:06:38,890 --> 00:06:45,070 Once you've finished downloading you can click it on this tab to launch the installer lets minimize 84 00:06:45,070 --> 00:06:51,820 the browser here we can drag the PI charm icon into the folder icon to finish the installation 85 00:06:55,950 --> 00:07:03,760 once you finish installing pi charm right click on it to launch I'll close all these other windows once 86 00:07:03,760 --> 00:07:11,650 the PI term is launched click on Create new project and this window we will choose pure Python on the 87 00:07:11,650 --> 00:07:12,000 top. 88 00:07:14,370 --> 00:07:16,680 Here we can create the name of the project. 89 00:07:16,950 --> 00:07:23,580 In this lesson we will be programming drums so we can set it to p y Tello with the name of the drone. 90 00:07:24,330 --> 00:07:25,610 If you don't like this name. 91 00:07:25,620 --> 00:07:28,560 Feel free to change it to any project name you wish. 92 00:07:29,610 --> 00:07:32,850 Next click on project interpreter. 93 00:07:32,850 --> 00:07:36,840 The default setting will be set to use virtual EMV. 94 00:07:36,840 --> 00:07:42,420 You may not be familiar with it so we will be using the python three point seven point two which we 95 00:07:42,420 --> 00:07:51,060 just installed choose existing interpreter and click on the dots now choose sys interpreter located 96 00:07:51,060 --> 00:07:52,010 on the left side. 97 00:07:54,770 --> 00:08:02,510 The default interpreter will be showing you as are slash local slash bins slash Python three point seven. 98 00:08:02,660 --> 00:08:08,720 If you scroll down you will see Python 2.0 something which is the python version originally installed 99 00:08:08,750 --> 00:08:13,970 when you bought your Mac the Python 3 in your libraries the one we just install now. 100 00:08:14,580 --> 00:08:21,030 But this is just a link to us our slash local slash and burn slash Python 3. 101 00:08:21,040 --> 00:08:26,140 Here we will set the interpreter to this python 3 by choosing this. 102 00:08:26,140 --> 00:08:32,260 Once we install a newer version of Python the computer will automatically choose the newer python version 103 00:08:34,010 --> 00:08:36,260 once we are done setting the interpreter here. 104 00:08:36,350 --> 00:08:41,860 OK as you see that the existing interpreter is set as Python 3. 105 00:08:42,060 --> 00:08:44,210 You can click on Create. 106 00:08:44,550 --> 00:08:47,790 You may find this tutorial window but we'll just skip it. 107 00:08:50,930 --> 00:08:56,780 Here I want you to check the left side corner of the screen where you will find pea y tallow which is 108 00:08:56,780 --> 00:08:59,720 the project name we created earlier. 109 00:08:59,720 --> 00:09:06,340 Right click on the P1 Tello and choose new then choose new python file. 110 00:09:06,340 --> 00:09:10,660 Let's set the file name to Main and press okay. 111 00:09:10,810 --> 00:09:14,470 And this file we will set to print test to run this code. 112 00:09:14,470 --> 00:09:18,610 We need to set the configuration on your right corner. 113 00:09:18,610 --> 00:09:23,950 You will find and configuration click on it to open up this window. 114 00:09:25,120 --> 00:09:28,750 Click on the plus button and choose python. 115 00:09:28,790 --> 00:09:33,040 You can set the name to whatever is easy for you to understand. 116 00:09:33,110 --> 00:09:38,170 In this example I will set it to go. 117 00:09:38,210 --> 00:09:40,280 Now we need to choose the script path. 118 00:09:40,940 --> 00:09:47,990 If you click on the file icon on the right you will see main dot P Y which we created earlier. 119 00:09:47,990 --> 00:09:55,510 Now press open check to see if the Python interpreter is set to Python three point seven. 120 00:09:55,790 --> 00:10:04,260 If it is all correct click OK after you added the configuration you will see a green triangle icon on 121 00:10:04,260 --> 00:10:08,360 the right corner once you click on the Green Triangle. 122 00:10:08,380 --> 00:10:14,790 The process will start you will find the results of your script on the bottom of the screen. 123 00:10:14,980 --> 00:10:19,390 Once you've completed all these steps you are done setting up your environment. 124 00:10:21,960 --> 00:10:27,840 Although we have completed all the steps there are a few more setting changes that I will make for you 125 00:10:27,900 --> 00:10:30,310 so you can see my script better. 126 00:10:30,600 --> 00:10:34,530 If you prefer these changes feel free to adjust your settings as well. 127 00:10:35,710 --> 00:10:41,240 I click on PI term located on the left corner of the screen and choose preferences. 128 00:10:41,280 --> 00:10:45,980 Now choose appearances the default theme is set to a dark color. 129 00:10:45,990 --> 00:10:48,750 So I will change it to light and apply. 130 00:10:49,890 --> 00:10:54,150 You will see that the entire screen changed to a brighter color. 131 00:10:54,150 --> 00:11:02,120 Also I will go on to choose editor here all choose font and change the font size to 30. 132 00:11:02,160 --> 00:11:04,670 I'm doing these changes for the purpose of teaching. 133 00:11:04,680 --> 00:11:12,040 So if you are fine with the default settings you do not have to make these adjustments. 134 00:11:12,040 --> 00:11:15,140 I also want to introduce you to the debugger function. 135 00:11:15,550 --> 00:11:19,460 Let's set a variable a with 10 and print a. 136 00:11:19,720 --> 00:11:24,820 You can click the blank next to the number and you will see this red circle up here. 137 00:11:24,850 --> 00:11:30,300 Now go onto the right corner to find a bug shape button once you press this button. 138 00:11:30,400 --> 00:11:37,930 You will be a debugger mind the process will stop at the breakpoint which is where you set the red circle. 139 00:11:37,930 --> 00:11:44,170 You can see the value set in variable a and also see the result showing the bottom part of your screen. 140 00:11:44,710 --> 00:11:50,380 You can use this debugger mode to check how the script is processing and also find any errors that you 141 00:11:50,380 --> 00:11:57,250 may have made and the lessons we will mainly be using the screen button to run the script. 142 00:11:57,490 --> 00:12:00,060 And this debugger mod. 143 00:12:00,460 --> 00:12:04,300 These features will be supported in the community version. 144 00:12:04,300 --> 00:12:12,030 So for those of you who will not be using more features you don't have to get the professional version. 145 00:12:12,160 --> 00:12:17,680 Let me clear the breakpoint and go onto the view on the top left of the screen. 146 00:12:17,680 --> 00:12:20,240 Here you will find toolbar. 147 00:12:20,380 --> 00:12:25,770 Once you click this you will see that the buttons have moved to the left side here. 148 00:12:25,840 --> 00:12:28,950 You will also see some more functions. 149 00:12:29,020 --> 00:12:35,720 Earlier I had this green triangle button to run the script but you can also set a shortcut key. 150 00:12:36,040 --> 00:12:39,430 Go to the PI chime and choose preferences. 151 00:12:39,430 --> 00:12:43,610 Choose key map and search run using the search bar. 152 00:12:44,170 --> 00:12:49,110 You can find run and the default short key set to f 10. 153 00:12:49,120 --> 00:12:54,880 I can change the settings by double clicking on run choose keyboard shortcut here. 154 00:12:54,880 --> 00:12:59,190 I will change the shortcut to control R and set the second stroke. 155 00:12:59,200 --> 00:13:03,970 Also to stroke are then hit ok again. 156 00:13:04,150 --> 00:13:09,420 OK to go back to the script. 157 00:13:09,620 --> 00:13:16,250 Currently we are in debugger mode so we need to hit this red square button to exit the debugger mode. 158 00:13:16,280 --> 00:13:20,290 Now I can hit control are twice to run the script. 159 00:13:20,420 --> 00:13:22,510 You can see that the result is showing. 160 00:13:22,640 --> 00:13:26,090 Even though I did not hit the Green Triangle button. 161 00:13:26,090 --> 00:13:30,070 Feel free to change the shortcut key to whatever key that works best for you. 162 00:13:31,190 --> 00:13:34,730 OK finally we've completed setting up the environment. 163 00:13:34,730 --> 00:13:38,420 Now let's go onto the next lesson and start programming the drones.
