1 00:00:03,330 --> 00:00:10,500 Hey, in today's bonus example, I want to work on yesterday's bonus example where we build this script. 2 00:00:10,530 --> 00:00:16,710 If you don't have this, you can find it attached in the lecture resources in this lecture for your 3 00:00:16,710 --> 00:00:17,700 convenience. 4 00:00:19,200 --> 00:00:22,640 The script we developed yesterday in bonus examples. 5 00:00:22,640 --> 00:00:30,450 So what it does is it allows the user to enter FT and inches such as 312 and then it replies. 6 00:00:32,740 --> 00:00:36,700 With this message, converting those feet and inches to meters. 7 00:00:36,700 --> 00:00:43,720 And then it also says if that kids can use this light or not, depending on how tall that kid is. 8 00:00:44,440 --> 00:00:46,870 So if it's below one meter. 9 00:00:49,050 --> 00:00:54,400 That's kids cannot use the slides, otherwise they can use it as it is the case here. 10 00:00:54,420 --> 00:00:55,770 1.2 metres. 11 00:00:56,940 --> 00:01:01,290 Now we want to improve this script today. 12 00:01:02,530 --> 00:01:05,560 By splitting it across different files. 13 00:01:08,690 --> 00:01:11,860 Of importing those files in the main file. 14 00:01:11,870 --> 00:01:14,210 So how would we do this? 15 00:01:15,110 --> 00:01:22,580 Well, you probably know that we normally take the functions and put them in separate files. 16 00:01:25,040 --> 00:01:27,230 So we have a post function. 17 00:01:29,260 --> 00:01:36,070 Which pauses the string that the user enters in the command line and it returns a dictionary. 18 00:01:36,780 --> 00:01:41,680 Then we have this convert function which gets FT and inches as numbers. 19 00:01:42,940 --> 00:01:45,250 And it converts them to meters. 20 00:01:46,240 --> 00:01:52,560 What I'll do now is I will consider that this program may become bigger in the future. 21 00:01:52,570 --> 00:01:56,480 So I would go and right click on bonus. 22 00:01:56,500 --> 00:02:01,240 This is a folder where bonus 14 is. 23 00:02:02,610 --> 00:02:12,330 So Bono's 14 is an empty file and in bonus 14 I'm going to place all the codes of bonus 13. 24 00:02:12,600 --> 00:02:14,580 So copied and pasted here. 25 00:02:14,850 --> 00:02:19,170 And then I'm going to put this function into a separate file. 26 00:02:20,250 --> 00:02:24,600 You can do that manually by creating a file inside. 27 00:02:24,600 --> 00:02:29,190 Bonus of bonus is the folder which contains bonus 14. 28 00:02:29,190 --> 00:02:38,460 So in the same folder you want to manually create a new file or you can use the par charm refactoring 29 00:02:38,460 --> 00:02:42,720 feature to create that file automatically. 30 00:02:44,880 --> 00:02:47,370 For that you need to select. 31 00:02:48,540 --> 00:02:49,680 The function. 32 00:02:50,560 --> 00:02:59,890 The entire function and right click and go to refactor and then you want to go to move. 33 00:03:00,010 --> 00:03:03,430 So you want to move that function to another file. 34 00:03:03,430 --> 00:03:09,810 So you want to move it from bonus 14 the current file to another file. 35 00:03:09,820 --> 00:03:12,160 So let's say this is going to be. 36 00:03:13,230 --> 00:03:15,930 Passers, passers. 37 00:03:15,930 --> 00:03:19,050 You can just say passers or you can say passers. 38 00:03:19,050 --> 00:03:19,980 14. 39 00:03:21,210 --> 00:03:23,130 Wherever you prefer, I'll just keep it. 40 00:03:23,130 --> 00:03:26,760 Parsers $0.14 and press on refactor. 41 00:03:27,240 --> 00:03:28,890 This is what happened now. 42 00:03:30,690 --> 00:03:36,120 One is that the function purser disappeared from Bones 14. 43 00:03:36,600 --> 00:03:41,490 Second is that this line was added by Parcham charm. 44 00:03:41,850 --> 00:03:49,110 This is saying from bonus that Porsche's 14 import pause parse was the name of the function. 45 00:03:49,290 --> 00:03:58,040 Bonus is the name of this folder and parsers 14 is the file that was created by Power charm. 46 00:03:58,290 --> 00:04:01,140 So parsers 14 is this file. 47 00:04:01,500 --> 00:04:06,120 And the this file contains the definition of the parse function. 48 00:04:07,960 --> 00:04:12,190 So this is an automatic process that offers. 49 00:04:12,190 --> 00:04:14,650 But you can, of course, do that manually. 50 00:04:14,650 --> 00:04:22,600 As I was explaining you, right click, create the file, put the function in there, and then import 51 00:04:23,830 --> 00:04:25,010 parts from here. 52 00:04:25,030 --> 00:04:28,270 Now, the way to import powers is. 53 00:04:29,590 --> 00:04:30,910 There are two ways actually. 54 00:04:30,910 --> 00:04:37,110 So this is one way from bonus dot passers for teen import pause or both. 55 00:04:37,120 --> 00:04:41,440 You can also say just from posters for teen. 56 00:04:42,710 --> 00:04:43,880 Import pass. 57 00:04:43,880 --> 00:04:45,590 This would also work. 58 00:04:47,340 --> 00:04:54,750 This works because pastors 14 and bonus 14 are in the same directory. 59 00:04:54,750 --> 00:04:56,520 So this works. 60 00:04:56,790 --> 00:05:06,390 But this also works because bonus is located in the project directory in the patch or project directory. 61 00:05:06,390 --> 00:05:08,520 And that directory is also. 62 00:05:09,580 --> 00:05:15,580 Included in the namespace, so both versions are fine to use. 63 00:05:16,240 --> 00:05:20,050 Let's try the same with the convert function. 64 00:05:20,050 --> 00:05:22,840 I'm going to right click over convert. 65 00:05:23,590 --> 00:05:26,010 Go to refactor, go again to move. 66 00:05:26,020 --> 00:05:28,540 This time we want to give this another name. 67 00:05:28,600 --> 00:05:33,040 So converters maybe 14. 68 00:05:34,140 --> 00:05:41,010 Press refactor and again the convert function was moved out of here. 69 00:05:41,040 --> 00:05:52,230 This line was added and a converters 14 dot p file was generated with the definition of convert inside. 70 00:05:55,000 --> 00:05:57,160 So that is our front end. 71 00:05:58,720 --> 00:06:05,800 Now we get those functions, so we have them here and we ask the user to enter, feed on inches. 72 00:06:05,890 --> 00:06:11,590 We create this variable pause equal to pause filled inches. 73 00:06:13,550 --> 00:06:23,600 So you see that post is directly referred to as opposed to being serves 14. 74 00:06:23,930 --> 00:06:37,550 This would also work, but you'd have to do import poor service 14, which is yet another way of importing. 75 00:06:38,900 --> 00:06:41,390 So feel free to use any of them. 76 00:06:42,260 --> 00:06:44,180 I'll just keep it as it is. 77 00:06:45,740 --> 00:06:46,490 Supports. 78 00:06:46,490 --> 00:06:47,600 And then we got the results. 79 00:06:47,600 --> 00:06:49,970 We print out that string. 80 00:06:50,000 --> 00:06:53,900 We check if the result is less than one and we print that. 81 00:06:54,830 --> 00:06:55,760 String. 82 00:06:56,150 --> 00:06:58,640 Otherwise, we print that other string. 83 00:06:59,150 --> 00:07:04,670 So if I run this, it's going to work just fine. 84 00:07:06,230 --> 00:07:06,530 Right. 85 00:07:06,530 --> 00:07:11,150 So that was about this video I used to modules. 86 00:07:11,150 --> 00:07:21,500 This time you could also use one single module and put both the convert and the pause function in one 87 00:07:21,500 --> 00:07:22,570 single file. 88 00:07:22,610 --> 00:07:24,830 Why did I use two files? 89 00:07:24,860 --> 00:07:29,450 Well, because I think these functions are a bit different from each other. 90 00:07:30,620 --> 00:07:33,890 So one is for parsing, another is for converting. 91 00:07:33,950 --> 00:07:34,580 So. 92 00:07:35,890 --> 00:07:44,800 I foresee that in the future I'll have more passing functions and that will allow me to extend the program 93 00:07:44,800 --> 00:07:47,620 easier, the app easier. 94 00:07:47,770 --> 00:07:51,310 So later I can just add more pass functions here. 95 00:07:52,680 --> 00:07:55,050 Maybe I want to pause different. 96 00:07:56,080 --> 00:07:57,370 Metric units. 97 00:07:57,370 --> 00:08:07,360 So I can add those functions in here, although it is debatable whether it is a good idea to put both 98 00:08:07,360 --> 00:08:09,580 converts and parts in one single file. 99 00:08:09,580 --> 00:08:11,950 So both ways are fine. 100 00:08:13,530 --> 00:08:14,400 Don't overthink. 101 00:08:14,400 --> 00:08:15,180 Think about that. 102 00:08:17,790 --> 00:08:19,110 And that was about this video. 103 00:08:19,140 --> 00:08:19,650 Thanks a lot. 104 00:08:19,680 --> 00:08:20,280 See you later.
