1 00:00:06,770 --> 00:00:08,930 Hello and welcome to. 2 00:00:10,300 --> 00:00:20,580 I am Jew, I was I am a Jew, I do I stands for graphical user interface in simple terms. 3 00:00:20,980 --> 00:00:31,660 This is what you see on the screen when you and Microsoft Excel or Wall or pie chart Python is scripting 4 00:00:31,660 --> 00:00:37,090 language, so it's normally excluded from the command line. 5 00:00:37,660 --> 00:00:41,930 And to interact with Python script, you use command line. 6 00:00:42,490 --> 00:00:44,950 Well, this is going to change today. 7 00:00:45,310 --> 00:00:49,020 Python have multiple libraries for constructing July. 8 00:00:49,480 --> 00:00:59,970 We will use a new library called by in J.Y. Although it's new, it will allow us to create professional 9 00:01:00,430 --> 00:01:07,210 joy in a matter of minutes and with much lesser code than the other libraries. 10 00:01:07,660 --> 00:01:18,430 The code on the screen will create a window containing a text and an input and an OK, but it will create 11 00:01:18,430 --> 00:01:26,440 this window and then it will wait for an event to happen, will use the read method that will return 12 00:01:26,740 --> 00:01:34,870 an event and event and event is, for example, clicking Dalkey button or clicking the button. 13 00:01:35,320 --> 00:01:39,680 And the value is, for example, the value inside the input. 14 00:01:39,730 --> 00:01:43,520 But but how is this layout construct? 15 00:01:43,930 --> 00:01:51,220 Simply the window that will appear is shown on the screen and the layout is a list of lists. 16 00:01:51,640 --> 00:01:55,710 So a list construct are all in the window. 17 00:01:56,050 --> 00:02:03,040 So the text label appears first then then then the bottom right. 18 00:02:03,280 --> 00:02:09,940 With those five lines of code, we construct a fully functional GeoEye. 19 00:02:11,640 --> 00:02:21,960 There are two main types of windows that we can use our own shop window and a position when the window 20 00:02:21,960 --> 00:02:31,020 is used to read one time value from the user, for example, the slogan should read one time from the 21 00:02:31,020 --> 00:02:38,060 user to allow him to log into the system or, for example, entering a file name to be open. 22 00:02:39,120 --> 00:02:46,680 The persistent window and other hand, will be displayed until the program ends, which means that it 23 00:02:46,680 --> 00:02:54,690 is inside ELU that periodically read the window to get its advance envelope with the reading. 24 00:02:54,690 --> 00:02:58,300 Math and reading happens inside the. 25 00:02:58,950 --> 00:03:06,510 You may have noticed the time out parameter in it sometimes when the application is doing something 26 00:03:06,750 --> 00:03:07,690 that takes time. 27 00:03:08,070 --> 00:03:13,720 The window may not respond to other action and may even seems to hang. 28 00:03:14,130 --> 00:03:18,320 Surely you have seen this in Windows, Linux and MapQuest. 29 00:03:18,720 --> 00:03:26,790 When the program is busy executing something and you click on the application, it has well to resolve 30 00:03:26,790 --> 00:03:28,430 this we use time. 31 00:03:28,770 --> 00:03:34,380 So the July is number one and the time out is in Mellissa. 32 00:03:34,560 --> 00:03:41,470 You may have find some by simple GeoEye programs that set the time and value to zero. 33 00:03:41,670 --> 00:03:42,940 This is very dangerous. 34 00:03:43,230 --> 00:03:52,520 Your program will consume 100 percent of the CPU it's recommended you do not use by less than then, 35 00:03:52,530 --> 00:03:52,900 Melyssa. 36 00:03:54,220 --> 00:03:58,450 Now, that method will allow you to update the value of an element. 37 00:04:00,280 --> 00:04:08,740 To create a menu, you specify the menu in much the same way as the Winnaleah, for example, the file 38 00:04:09,100 --> 00:04:16,420 menu contains a list of the file options menu, contains a list of those options, etc.. 39 00:04:16,630 --> 00:04:16,960 OK. 40 00:04:17,870 --> 00:04:24,110 So let's fire by trying to begin exploring why some mildewy. 41 00:04:26,990 --> 00:04:32,870 When you try to run I in July on Lennix. 42 00:04:34,040 --> 00:04:40,980 You may receive an error message because AT&T is not an is. 43 00:04:42,380 --> 00:04:44,540 And this is Amodio required by. 44 00:04:45,330 --> 00:04:49,980 By simple joy, in order to show I have created. 45 00:04:53,260 --> 00:04:56,560 And let's in his tool, I think, do I? 46 00:04:58,350 --> 00:05:00,630 And check how it will all. 47 00:05:02,000 --> 00:05:06,770 First, let's install by Sempill Joy. 48 00:05:09,730 --> 00:05:11,110 Then let's play. 49 00:05:18,800 --> 00:05:22,610 Ileum bought by Sempill GeoEye as S.G.. 50 00:05:27,970 --> 00:05:31,860 Then let's use as little Bob. 51 00:05:34,160 --> 00:05:44,660 And let's execute the script and displayed an error message saying no module name began doing this tool 52 00:05:44,820 --> 00:05:45,590 decanted. 53 00:05:46,710 --> 00:05:48,840 Ingenix will use. 54 00:05:49,940 --> 00:05:51,770 Zuda, Apte. 55 00:05:52,630 --> 00:05:56,280 In his tool, Python three t.K. 56 00:06:00,170 --> 00:06:02,720 And this willingness to decanted. 57 00:06:08,890 --> 00:06:12,850 Now, let's rerun our script and.
