Atom is a powerful and very efficient editor for writing and 5 00:00:11,309 --> 00:00:18,510 executing Python code. This lecture is specifically for windows, so for Mac 7 00:00:18,510 --> 00:00:24,869 users please go to the next lecture. So before what we did was we installed 9 00:00:24,869 --> 00:00:30,660 Python and we tried a python interactive session in the command prompt and we 11 00:00:30,660 --> 00:00:36,059 also created a python program using a simple editor such as Notepad or 13 00:00:36,059 --> 00:00:40,860 whatever editor you had in on your Windows, so now we're going to use 15 00:00:40,860 --> 00:00:45,570 another editor which is Atom and you need to go and install it from and 17 00:00:45,570 --> 00:00:54,480 download it from the Atom official web Page, just click the button there. 19 00:00:54,480 --> 00:01:01,800 Say file and it will take a while until it downloads. Great, the download process 21 00:01:01,800 --> 00:01:08,100 has finished now so I'm going to click on Atom, click on run to run 23 00:01:08,100 --> 00:01:16,380 the installation and yeah you have to wait a while until Atom is installed. 25 00:01:16,380 --> 00:01:23,189 And yeah, the installation was quick and now Atom has been opened on my Windows, however I would 27 00:01:23,189 --> 00:01:29,909 like to close it here and show you the standard way of how to open Atom, so the 29 00:01:29,909 --> 00:01:35,670 way that you'd normally open Atom when you start programming so one way to 31 00:01:35,670 --> 00:01:41,430 open Atom is to browse through your programs and open Atom by clicking. 33 00:01:41,430 --> 00:01:48,630 However that we open atom in a random directory so the most efficient way to 35 00:01:48,630 --> 00:01:53,790 open Atom is to go to the directory where you have your programs so the 37 00:01:53,790 --> 00:01:58,920 program that we have is myprogram.py. And then outside in here right click 39 00:01:58,920 --> 00:02:04,649 and go to open with Atom, but if you don't see open with Atom like I do. so 41 00:02:04,649 --> 00:02:09,250 I don't have open with Atom for now, then go and open Atom 43 00:02:09,250 --> 00:02:22,120 for your programs. Go to file, settings and then check these two options so this 45 00:02:22,120 --> 00:02:27,250 options were under system, under the system tab of the settings menu and I 47 00:02:27,250 --> 00:02:35,050 close Atom and I right click and now you should see this menu in here. Open it 49 00:02:35,050 --> 00:02:41,620 and you should now see this view but if you see, if you don't see the tree 51 00:02:41,620 --> 00:02:50,260 view in here, the directory tree view, go to view and then toggle tree view so you can 53 00:02:50,260 --> 00:02:59,950 toggle it off and on. You can close this and then to open your program, so to edit 55 00:02:59,950 --> 00:03:04,989 your program you simply double-click your file your Python file and yeah, you 57 00:03:04,989 --> 00:03:13,209 start writing. Print. Start adding more code and always press ctrl s to save and 59 00:03:13,209 --> 00:03:21,010 now to execute this code you can either go here and open your command window 61 00:03:21,010 --> 00:03:26,830 here with Shift right click or there is a more efficient way to do it. You need 63 00:03:26,830 --> 00:03:34,870 to go to file settings, packages, sorry install, you want to install a new 65 00:03:34,870 --> 00:03:48,610 package and search for that platformio 67 00:03:51,340 --> 00:03:58,299 click install and so this is the package that we will install or will integrate a 69 00:03:58,299 --> 00:04:04,510 terminal, a command line inside Atom so you don't have to use external windows 71 00:04:04,510 --> 00:04:10,180 and native windows command line and you can run your programs from within Atom. 73 00:04:10,180 --> 00:04:15,610 All right, platform ide terminal was installed successfully, you can close the 75 00:04:15,610 --> 00:04:22,510 settings tab and so now you should see this plus icon in here, click on the icon. 77 00:04:22,510 --> 00:04:26,870 Will open a new terminal so now this is 79 00:04:26,870 --> 00:04:32,030 opening the current directory which reflects the directory of your Atom 81 00:04:32,030 --> 00:04:37,400 directory, so of your programs. Now you can go ahead and type in commands you to 83 00:04:37,400 --> 00:04:43,880 run your Python program, so my tab for auto completion and that will 85 00:04:43,880 --> 00:04:48,260 auto complete like that, don't worry about this. This just means the current 87 00:04:48,260 --> 00:04:55,520 directory, so when you do Tab, Tab will add this. Ignore it and press Enter and 89 00:04:55,520 --> 00:05:02,690 you see the program output in the terminal. You can clear the terminal from 91 00:05:02,690 --> 00:05:07,970 the codes from previously executed commands and of course you can call 93 00:05:07,970 --> 00:05:13,730 previously executed commands with the upper arrow key. Execute again and don't 95 00:05:13,730 --> 00:05:21,380 confuse executing a program with opening a Python interactive session, so here you 97 00:05:21,380 --> 00:05:28,880 write Python code like print 7 for example interactively but if you exit 99 00:05:28,880 --> 00:05:36,229 this because I see some students will go ahead and run Python code in here but 101 00:05:36,229 --> 00:05:43,820 this is wrong, this is not Python, this is windows, the windows command line, so 103 00:05:43,820 --> 00:05:49,820 don't do that instead write Python code inside an interactive session or inside 105 00:05:49,820 --> 00:05:54,020 the Python file. That's the idea and this is Atom. I hope you like it 107 00:05:54,020 --> 00:05:57,160 and I'll talk to you later. 6401
