WEBVTT 00:00.880 --> 00:01.240 Okay. 00:01.240 --> 00:06.240 Now let's continue and see how we can complete this. 00:06.280 --> 00:06.680 Okay. 00:07.240 --> 00:09.480 So here we are. 00:09.520 --> 00:11.800 We have done it just for interface. 00:11.840 --> 00:12.280 Okay. 00:12.600 --> 00:19.760 Now let's go and do this for uh other one which was Mac address. 00:20.200 --> 00:23.880 So parser dot add option. 00:24.400 --> 00:36.040 And here for Mac address I'm going to use dash M and it is going to be Dash dash Mac okay. 00:36.560 --> 00:40.600 And the value is going to be new Mac okay. 00:42.960 --> 00:43.280 Okay. 00:43.320 --> 00:44.360 How about help. 00:45.520 --> 00:48.520 The help is going to be equal to. 00:50.600 --> 00:52.680 Let's say new Mac address. 00:56.280 --> 00:56.720 Okay. 00:57.160 --> 00:58.120 Now it is done. 00:58.120 --> 01:00.800 And it is not yet completed okay. 01:01.160 --> 01:03.960 So as you see here, we have to think. 01:04.000 --> 01:04.400 Okay. 01:05.840 --> 01:06.640 Right here. 01:06.640 --> 01:08.560 You see, we have to think. 01:08.880 --> 01:10.520 And come on, let me show you. 01:11.600 --> 01:15.560 We have dash, let me clear this first. 01:18.080 --> 01:18.720 We have. 01:20.960 --> 01:21.320 Dash. 01:21.320 --> 01:22.680 Dash interface. 01:25.200 --> 01:27.400 Which is going to be ETA zero okay. 01:27.440 --> 01:36.440 And we have dash dash Mac which is going to be 0011 and 2233 and four four. 01:38.880 --> 01:40.680 Four four 4 or 5 five okay. 01:40.960 --> 01:42.080 So here you see two things. 01:42.080 --> 01:44.200 One of them is the interface. 01:44.200 --> 01:46.280 And then the value that we have here. 01:46.320 --> 01:46.760 Okay. 01:47.480 --> 01:49.600 So one of them is going to be the argument. 01:49.600 --> 01:52.480 The other one is going to be the option okay. 01:52.520 --> 01:54.800 So these are going to be the options. 01:54.800 --> 01:59.760 And these are going to be the interface and dash dash Mac are arguments. 01:59.840 --> 02:04.360 So we need to specify that right in here here Okay. 02:05.600 --> 02:11.360 And we need to store these, both these two things into two variable. 02:11.400 --> 02:11.800 Okay. 02:12.320 --> 02:13.520 So how can we do that. 02:13.680 --> 02:16.920 Let's create a tuple here. 02:17.320 --> 02:18.240 I'm going to name it. 02:18.280 --> 02:20.040 One of them is option. 02:20.040 --> 02:22.240 And the next one is going to be argument. 02:22.280 --> 02:23.040 Okay. 02:23.080 --> 02:27.320 So we never we're going to we never use argument okay. 02:27.360 --> 02:28.200 In our code. 02:28.680 --> 02:32.360 And we always use options. 02:32.680 --> 02:36.800 So we have option if you want to access the interface. 02:36.800 --> 02:42.160 So you need to use option dot dist which is the value anything you write here. 02:42.200 --> 02:42.360 Okay. 02:42.400 --> 02:48.640 For example option dot interface will give you the interface option dot new Mac will give you the new 02:48.640 --> 02:49.400 Mac address. 02:49.520 --> 02:51.200 Anything you write into this. 02:51.200 --> 02:52.000 This here. 02:52.040 --> 02:52.440 Okay. 02:53.560 --> 03:00.000 So here instead of giving these here I can use options. 03:00.280 --> 03:04.040 Dot what is this this interface okay. 03:04.080 --> 03:05.670 So let's use that interface. 03:06.470 --> 03:08.630 And also this one. 03:11.310 --> 03:15.070 Option dot new Mac. 03:15.870 --> 03:18.910 So now save it and let's go again. 03:20.630 --> 03:22.150 Let me see. 03:23.030 --> 03:26.190 Okay Dash I okay. 03:26.190 --> 03:29.550 Interface is going to be e th zero. 03:31.430 --> 03:38.910 And dash m which is Mac address is going to be 0011 and 223344. 03:39.150 --> 03:42.190 And we have for example seven seven. 03:42.190 --> 03:43.150 Now let's hit enter. 03:43.150 --> 03:46.390 And you see changing Mac address for it is zero. 03:46.390 --> 03:48.110 And this is going to be the Mac address. 03:48.750 --> 03:52.910 Let's uh use ifconfig and see if it is changed. 03:52.910 --> 03:54.190 Of course it is changed. 03:54.510 --> 04:03.270 Now this time I'm going to use dash dash Mac and dash dash interface okay. 04:06.190 --> 04:06.950 Interface. 04:07.510 --> 04:11.230 And let's change this to 99. 04:12.670 --> 04:15.990 And you see we have no error. 04:16.150 --> 04:17.790 And let's use ifconfig. 04:17.790 --> 04:21.830 You see that it is changed successfully. 04:22.110 --> 04:25.190 So now I think it is almost completed. 04:25.230 --> 04:25.950 Okay. 04:25.990 --> 04:28.950 The program and it is working perfect. 04:29.990 --> 04:33.510 And as you see the code is kind of missing. 04:33.550 --> 04:37.710 We could change this into a function because function is very good. 04:37.710 --> 04:39.790 Whenever we use it we call it. 04:40.870 --> 04:44.190 And if you need this in multiple times in multiple places. 04:44.190 --> 04:46.550 So you need to copy and paste the whole code. 04:47.150 --> 04:52.150 But if it is inside a function you only call the function. 04:52.190 --> 04:52.870 Okay. 04:52.910 --> 04:55.430 You just import the file just like this. 04:55.630 --> 04:57.750 And then you can use the function. 04:57.750 --> 04:59.150 That is very easy. 04:59.470 --> 05:07.390 So let's go and do something with creating function, putting all this stuff into functions and use 05:07.390 --> 05:07.710 it.
