WEBVTT 00:00.480 --> 00:07.770 Now in this tutorial we will create a calculator application and they want to calculate application 00:08.890 --> 00:15.450 that will perform addition subtraction multiplication and division functionalities along with we really 00:15.450 --> 00:25.540 do chording for how to clear the console and how we can create the other functionality. 00:25.800 --> 00:32.470 With the help of calculator application let's create a python file for a calculator. 00:35.380 --> 00:45.750 Now in this file let's import the package from thing to import star. 00:45.760 --> 00:52.570 Now I have created our data card Cal inside. 00:52.570 --> 01:03.300 This way we called call that Duffys we will create the title here get a dark title. 01:04.080 --> 01:10.240 And let's give that eyeglass calculator. 01:12.070 --> 01:19.260 Application we have created a title with calculator application. 01:19.360 --> 01:30.270 We will see that I have created for Prechter and I'm going to pass non-value to dig operator. 01:30.810 --> 01:37.550 Similarly I will create an another variable named mystics on the square in port. 01:38.790 --> 01:41.670 And that is all string variable. 01:41.770 --> 01:45.320 It will handle things. 01:45.430 --> 01:51.770 Now I read as we know that a calculator is composed of full screen. 01:51.790 --> 02:00.790 So I will display the text Dickstein DSP text display is a text field. 02:01.300 --> 02:06.290 What it will take will create an angry feed for me in that. 02:06.320 --> 02:16.040 And Rivard I'm going to pause the gal the form which I'm going to use is inside the. 02:16.380 --> 02:19.660 I want the born days off. 02:22.130 --> 02:28.730 Trendies the size and that is that should be bored. 02:30.230 --> 02:43.020 You know what I want to do is after this option board I want to make stopping short of days like I want 02:43.340 --> 02:48.570 our text pre-cable and that takes variable here. 02:48.670 --> 02:52.430 I'm going to boss the text in. 02:53.020 --> 02:54.930 I will have the option. 02:55.450 --> 02:58.940 Beatty's equals tarty. 02:59.530 --> 03:11.110 I will have in Sark read co-option inside the tears fall and after that I will have background color 03:11.760 --> 03:19.030 and the background color is tall dark blue Florida blue collar. 03:19.030 --> 03:28.230 I want to use off of these I will have the justification option. 03:29.230 --> 03:33.430 I really have to justify your option here. 03:33.430 --> 03:39.510 The justification is write option. 03:40.230 --> 03:42.010 Great option. 03:43.070 --> 03:52.450 And hid in the great option I really use calls when physical store for me is giving me a deck dark grid 03:52.460 --> 03:53.400 option. 03:53.810 --> 04:00.680 We have done some cord where we have not the Carlon here. 04:00.770 --> 04:04.090 So it was giving me the error. 04:04.430 --> 04:07.230 Now we have done the chording for text just play. 04:07.340 --> 04:14.460 Now what we do is let's check this whether it is working or not. 04:14.520 --> 04:17.530 We're really quite hard men. 04:18.650 --> 04:20.720 Let's run this example. 04:20.840 --> 04:30.500 We're going there are good configurations where we type here the name mouse calculator we will select 04:30.500 --> 04:31.840 the python file. 04:32.330 --> 04:42.590 Just select this link this file and we will put on this project say it is giving me added of that unknown 04:42.590 --> 04:44.700 option text variable. 04:45.140 --> 04:56.610 Let's redefine the word and and this again no it does giving the error there is Boch. 04:56.720 --> 04:58.820 Let's see what data we are getting. 04:58.940 --> 05:02.900 We are getting these letters buried option calls Ben 05:09.950 --> 05:14.060 C we have created a calculator application with title. 05:14.370 --> 05:18.620 And inside this application we have created this text field. 05:18.940 --> 05:23.890 Let's do more code in this application. 05:23.910 --> 05:29.220 Now what we do is we will create buttons I will create victims. 05:29.280 --> 05:38.190 Seven is a tool but an option inside this an option I will pause that Kehl element. 05:38.300 --> 05:41.180 I really do paradox option here. 05:41.180 --> 05:50.140 I read all 16 similarly packed by option will be used Paraguay's also 16 I believe was video option 05:50.920 --> 05:58.950 made easy to 8 and after that I want the foreground color for can color. 05:58.960 --> 06:04.590 I want to use black. 06:04.750 --> 06:09.760 Similarly I really use background color for dark background color. 06:09.760 --> 06:13.580 No need to use the background color only for color is required. 06:13.890 --> 06:21.070 And after that I will use here the format option in this format option. 06:21.310 --> 06:30.340 Similarly I really use the aerial option we will have the size of 20 and up to date we will use the 06:32.080 --> 06:39.980 Boid option here now opt out of the board option which they Vorm to do is I want to have extra functionality 06:41.000 --> 06:47.320 like I want our text option text is equal to 7. 06:47.410 --> 07:01.620 Now the text option is being said I want the background color background is for W and timeworn the command 07:01.620 --> 07:04.150 option inside the command option. 07:04.160 --> 07:15.540 I've warned Lamda button click option inside this button click option and because here the an option 07:16.530 --> 07:23.870 dot grid inside this grid I want it should be displayed at 07:26.660 --> 07:29.660 SRL. 07:29.880 --> 07:41.590 Second column Fussle seated column by quilts to bite them click gating this arrow button click. 07:41.670 --> 07:42.820 Now let's see. 07:43.020 --> 07:53.370 It is giving me better insight to use here Ulam dark dark but don't click with this option.
