1 00:00:06,840 --> 00:00:07,510 Welcome back. 2 00:00:08,190 --> 00:00:10,260 In this lecture, we'll explore. 3 00:00:11,540 --> 00:00:15,500 The different ways to create layered. 4 00:00:16,440 --> 00:00:19,140 We will start by importing by Sam. 5 00:00:22,590 --> 00:00:23,880 As S.G.. 6 00:00:24,850 --> 00:00:27,760 Now, let's create a to do list player. 7 00:00:28,360 --> 00:00:34,090 I'll play a layout, which will be a list of list. 8 00:00:34,810 --> 00:00:37,470 This will be S.G. the next. 9 00:00:38,250 --> 00:00:39,510 There's one. 10 00:00:41,040 --> 00:00:47,430 And as Jadot input, I'll give it key in. 11 00:00:52,910 --> 00:01:01,320 Repeat this a couple of times and let's change these four or five. 12 00:01:03,900 --> 00:01:14,400 And now we have created earlier, so let's create our window and then we will use event and values will 13 00:01:14,400 --> 00:01:18,570 equal to win the DOT, right. 14 00:01:19,080 --> 00:01:19,680 And then. 15 00:01:21,340 --> 00:01:32,350 After we read it, we will use window that close our window display here and it have different tasks 16 00:01:32,830 --> 00:01:33,430 and. 17 00:01:34,290 --> 00:01:36,360 Inputs and we have forgot. 18 00:01:41,020 --> 00:01:43,240 OK, and cancel button shouldn't. 19 00:01:44,920 --> 00:01:46,720 Give the of. 20 00:01:47,900 --> 00:01:49,150 Unbuttons to. 21 00:01:52,950 --> 00:01:54,180 Or cancel. 22 00:01:55,810 --> 00:02:00,100 Whatever he wants, so if we. 23 00:02:01,420 --> 00:02:03,610 And there's some values in news. 24 00:02:05,370 --> 00:02:08,520 And we think it will be. 25 00:02:09,650 --> 00:02:18,570 Recorded what we have in print, the event and values, and now this is the. 26 00:02:21,530 --> 00:02:23,270 We have seen this previously. 27 00:02:24,080 --> 00:02:33,170 And obviously, there are multiple ways to create value that will make it much easier. 28 00:02:33,260 --> 00:02:33,710 So. 29 00:02:34,760 --> 00:02:47,480 I will create another layout, this will be an empty nest then for I in range of one to seven because 30 00:02:47,480 --> 00:02:49,310 we are having six rows. 31 00:02:50,290 --> 00:02:56,830 I will use pay out plus will equal to one or two. 32 00:02:57,650 --> 00:03:04,870 Of these, I will convert those to formatters string with the Value VI. 33 00:03:05,700 --> 00:03:08,640 And also this. 34 00:03:09,650 --> 00:03:13,340 And when they do finish, it's at our. 35 00:03:14,460 --> 00:03:15,140 OK. 36 00:03:15,270 --> 00:03:17,460 And cancel button. 37 00:03:18,570 --> 00:03:27,360 So we will Salyut plus equals and will create a list of list. 38 00:03:27,540 --> 00:03:29,120 Don't ever forget this. 39 00:03:29,430 --> 00:03:34,910 If I did not do this, it will create an error message. 40 00:03:35,550 --> 00:03:38,340 OK, so because. 41 00:03:39,860 --> 00:03:47,960 I am adding a list of less to the layout now let's copy this. 42 00:03:49,890 --> 00:03:52,040 Cells always use. 43 00:03:53,240 --> 00:03:54,380 Let's move this. 44 00:03:55,480 --> 00:03:56,680 What a mere. 45 00:04:02,930 --> 00:04:09,080 And we have created the same layout with a full OK, great. 46 00:04:09,860 --> 00:04:16,700 And of course, we can do the same thing using Alice the Channer, so. 47 00:04:17,620 --> 00:04:28,690 Let's try this, I'll just copy these cells in this and I'll remove this, I will create layout which 48 00:04:28,690 --> 00:04:32,860 will equal to Fushi Range. 49 00:04:34,330 --> 00:04:35,840 Of one seven. 50 00:04:36,220 --> 00:04:40,660 OK, let's try this and we have created. 51 00:04:42,300 --> 00:04:54,120 The same layout with a list comprehension, so this can allow us to save time and create a very complex 52 00:04:54,360 --> 00:04:58,140 layout with a few lines of code. 53 00:04:58,860 --> 00:05:01,810 Now let's create another layer. 54 00:05:02,130 --> 00:05:02,670 But. 55 00:05:03,560 --> 00:05:08,060 In a different way, I will create a function plate. 56 00:05:08,850 --> 00:05:12,180 Role, which will be index. 57 00:05:13,190 --> 00:05:13,910 And values. 58 00:05:16,590 --> 00:05:18,480 A2 is still not. 59 00:05:21,040 --> 00:05:25,830 Item of Fermat string open ended. 60 00:05:27,600 --> 00:05:29,550 Index, I will give it. 61 00:05:30,460 --> 00:05:31,600 Size. 62 00:05:33,130 --> 00:05:35,560 Equals eight characters. 63 00:05:36,670 --> 00:05:38,560 Then let's add. 64 00:05:39,970 --> 00:05:44,560 Campbell, the commonwealth will be. 65 00:05:45,820 --> 00:05:46,870 The ladies in here. 66 00:05:48,240 --> 00:05:52,140 It will also have a default value of the first Elliman and. 67 00:05:55,500 --> 00:05:59,040 I also gave a size of. 68 00:06:00,190 --> 00:06:05,230 Three and one, and let's also add. 69 00:06:06,120 --> 00:06:06,960 An impact. 70 00:06:07,800 --> 00:06:11,400 Which will have a key or format this thing. 71 00:06:12,920 --> 00:06:20,960 In of Digex, OK, now let's create. 72 00:06:21,940 --> 00:06:34,570 Values which were equal to a list of A, B, C, D, E, F, and we will create a layout, Dalia will 73 00:06:35,830 --> 00:06:42,220 list comprehension, create the role of AI and values. 74 00:06:43,100 --> 00:06:48,470 For I in range of 11. 75 00:06:50,950 --> 00:07:04,180 Again, as we have seen, we will add our OK and cancel bottoms and we have created our layout, let's 76 00:07:04,180 --> 00:07:04,720 cut. 77 00:07:05,610 --> 00:07:07,080 These two. 78 00:07:08,010 --> 00:07:08,500 Cells. 79 00:07:09,030 --> 00:07:14,910 Now, let's exclude these cells and we have created our layout. 80 00:07:17,940 --> 00:07:24,310 Is very cool and we have created this in a couple of lines. 81 00:07:24,660 --> 00:07:28,800 Now let me show you a couple of things. 82 00:07:29,550 --> 00:07:34,950 As I told you that the layout should be a list of list. 83 00:07:35,310 --> 00:07:44,460 If the layout is not a list of list, it will create an error message just like this one error creating 84 00:07:44,460 --> 00:07:48,210 window layout and instead of a list. 85 00:07:49,430 --> 00:07:52,460 That I found was class of. 86 00:07:53,260 --> 00:08:00,310 Something, this means that we are passing a list, not a list of lists. 87 00:08:00,760 --> 00:08:03,490 OK, this is very important. 88 00:08:03,940 --> 00:08:04,750 OK, so. 89 00:08:08,050 --> 00:08:14,690 And remarking that this is better when they. 90 00:08:19,200 --> 00:08:23,400 Is not a list of lists. 91 00:08:26,290 --> 00:08:30,520 Now, let's move on to something very important. 92 00:08:31,470 --> 00:08:40,710 We have seen in the last lecture how we can update an element in the wind, but let's refresh it. 93 00:08:41,310 --> 00:08:42,060 I just. 94 00:08:43,310 --> 00:08:46,910 Create a layout, which will be. 95 00:08:50,100 --> 00:08:50,910 Leaves. 96 00:08:52,130 --> 00:09:03,500 And there's something and then I'll add an important box and I'll give it a key equals. 97 00:09:04,640 --> 00:09:08,330 In then we will create another. 98 00:09:11,370 --> 00:09:14,550 I'll give a key equals. 99 00:09:16,920 --> 00:09:18,690 And I'll give it a size. 100 00:09:19,610 --> 00:09:28,610 Of print and one, because the default size is one character and finally our. 101 00:09:29,540 --> 00:09:31,880 By the way, there are multiple. 102 00:09:32,940 --> 00:09:44,940 Buttons, for example, we can we have subnet and these are just button names, so instead of OK and 103 00:09:44,940 --> 00:09:48,630 cancel, I'll use subnet and count. 104 00:09:49,720 --> 00:09:54,220 OK, now we have great layout, I'll copy these. 105 00:09:55,220 --> 00:10:03,380 Two, I will create wild two if event in. 106 00:10:04,470 --> 00:10:05,070 Ganzel. 107 00:10:11,340 --> 00:10:22,620 Is GW in close, then I'll break out of the blue elusive event equals submit. 108 00:10:25,580 --> 00:10:27,650 Window of. 109 00:10:30,950 --> 00:10:34,850 The date values of. 110 00:10:39,860 --> 00:10:48,710 We will close the window and we will PRAnd event and raise. 111 00:10:50,250 --> 00:10:56,750 Hey, now, let's ask you this, when I we have an error message. 112 00:10:58,530 --> 00:11:08,580 Sometimes when you have an error, your program will not respond, so I will close it and since are 113 00:11:08,580 --> 00:11:12,600 using trumpeter's, the kernel will stop. 114 00:11:14,910 --> 00:11:18,630 We will have to execute this again. 115 00:11:20,230 --> 00:11:25,640 Because the colonel is died and thus should be prent. 116 00:11:25,990 --> 00:11:27,810 Now let's do this again. 117 00:11:28,900 --> 00:11:35,890 OK, now we have a window, if we type something and press submit that updated this, we have seen this 118 00:11:35,890 --> 00:11:36,440 before. 119 00:11:36,550 --> 00:11:39,310 Nothing is new here, but. 120 00:11:40,280 --> 00:11:42,050 We also have. 121 00:11:42,970 --> 00:11:48,310 Seeing how we can create an event directly without. 122 00:11:49,720 --> 00:11:52,840 Pressing a button by using. 123 00:11:57,450 --> 00:11:58,860 Equals to. 124 00:12:01,010 --> 00:12:04,640 And we can modify this by using its name. 125 00:12:06,700 --> 00:12:14,440 So now, whenever I type something in years, it will update that. 126 00:12:17,590 --> 00:12:20,500 We have seen this before now.
