WEBVTT 00:00.960 --> 00:05.840 In one of the lecture we covered Python in Python basics. 00:05.840 --> 00:08.800 Okay, we covered Python variables okay. 00:09.080 --> 00:13.600 So here I'm going to show you how you can use variables okay. 00:14.200 --> 00:16.840 We need to use variables in here. 00:16.840 --> 00:25.080 As you see we have few things here that is necessary to put them into store them into variables. 00:25.080 --> 00:26.440 One of them is interface. 00:26.440 --> 00:28.560 The other one is Mac address. 00:28.600 --> 00:29.440 Okay. 00:29.440 --> 00:31.480 So let's do this. 00:31.520 --> 00:33.680 Let's create a variable name it interface. 00:33.880 --> 00:37.240 So this interface is equal to something right now. 00:37.240 --> 00:39.320 You see it is it is zero okay. 00:39.360 --> 00:40.560 Later you can change it. 00:40.680 --> 00:44.280 And also we have new Mac address. 00:44.720 --> 00:47.720 So it is equal to this thing right now. 00:48.120 --> 00:50.640 And that could be changed too. 00:50.640 --> 00:53.280 So let's add this from here okay. 00:53.320 --> 00:57.920 Use control X and use it here control V. 00:58.000 --> 01:01.360 And then use your new Mac here okay. 01:03.400 --> 01:04.520 Right here. 01:04.600 --> 01:07.680 Or maybe not there. 01:08.040 --> 01:09.680 Here, use a plus. 01:09.680 --> 01:12.080 And then your new Mac address. 01:12.120 --> 01:12.560 Okay. 01:17.200 --> 01:17.600 Okay. 01:17.880 --> 01:20.080 Now we have the new Mac address here. 01:21.760 --> 01:25.600 And it is time to use the interface variable. 01:25.640 --> 01:26.280 Okay. 01:26.320 --> 01:32.240 So the interface here we say for which it is zero if you're using LAN. 01:32.280 --> 01:33.240 So LAN zero. 01:33.640 --> 01:37.760 And here we need to use interface. 01:37.800 --> 01:38.200 Okay. 01:38.760 --> 01:43.760 Enter is and concatenate that with this one. 01:45.160 --> 01:45.640 Okay. 01:45.680 --> 01:46.480 Not really. 01:46.480 --> 01:48.600 Down 01:50.520 --> 01:53.840 here we have something. 01:53.880 --> 01:54.320 Okay. 01:56.560 --> 01:58.040 That is here. 02:01.840 --> 02:02.240 Okay. 02:04.830 --> 02:05.950 Good. 02:05.990 --> 02:08.110 Now we have interface right here. 02:08.110 --> 02:11.590 That is that we are using interface here. 02:11.590 --> 02:15.110 Be careful about these spaces here needs to be here okay. 02:15.110 --> 02:20.070 And also let's uh copy this part okay. 02:20.110 --> 02:30.310 Use Ctrl C to copy that and then just paste instead of E to zero and eth zero okay. 02:30.310 --> 02:37.310 Now we have a program that is looks a little better than that okay. 02:38.230 --> 02:39.990 Now again let me save this. 02:39.990 --> 02:44.830 This time I'm going to change it to for example six six okay. 02:44.870 --> 02:50.830 Save it and let's move to terminal I have opened the terminal right here okay. 02:50.870 --> 02:52.070 Let me use ifconfig. 02:54.150 --> 02:59.670 Now you see that the the Mac address it is five five okay. 02:59.710 --> 03:01.510 And let me use Python. 03:01.670 --> 03:04.270 We have mac changer.py hit enter. 03:04.790 --> 03:05.870 And again. 03:08.150 --> 03:12.910 Also let's add more thing like print. 03:12.910 --> 03:13.950 Use a print statement. 03:13.950 --> 03:15.110 Okay, I will do that. 03:15.470 --> 03:19.670 But before that let me see that if it is changed, of course it is changed. 03:19.670 --> 03:20.070 Okay. 03:20.830 --> 03:23.190 Here, right in here. 03:23.190 --> 03:29.830 Let's print a statement like changing a mac address for for this interface to this Mac address. 03:29.870 --> 03:30.910 Okay. 03:30.950 --> 03:31.870 Can we do that. 03:31.870 --> 03:33.430 Yes, we can do that okay. 03:33.470 --> 03:34.430 We are a programmer. 03:34.430 --> 03:37.230 So we are able to do anything we want okay. 03:38.110 --> 03:42.870 And here I'm going to changing tell changing. 03:45.070 --> 03:46.110 Mac address. 03:49.910 --> 03:51.830 To okay. 03:51.870 --> 03:53.310 Or we could use for. 03:58.470 --> 04:00.310 For what for interface. 04:00.310 --> 04:02.750 So we are using interface here. 04:02.870 --> 04:05.870 And then concatenating this with. 04:08.790 --> 04:09.500 This one. 04:09.740 --> 04:12.300 It is going to be new Mac address. 04:12.620 --> 04:15.020 Now let's see, how does it look like? 04:15.140 --> 04:15.540 Okay. 04:17.380 --> 04:18.020 Save it. 04:18.340 --> 04:23.220 Come to terminal and clear this. 04:30.500 --> 04:31.820 Okay. 04:31.820 --> 04:35.300 Or let's change this at seven seven. 04:35.300 --> 04:38.100 So okay. 04:38.140 --> 04:38.780 Save it. 04:39.020 --> 04:40.020 And here. 04:42.140 --> 04:43.380 Use ipconfig right. 04:43.380 --> 04:44.860 Then you see it is six six. 04:47.660 --> 04:53.940 And it is telling you that changing Mac address for eth0 to this one okay. 04:54.380 --> 04:57.180 And now let's see if it is changed or not. 04:59.780 --> 05:02.380 You see that it is changed to seven seven. 05:02.620 --> 05:03.340 Very good. 05:03.660 --> 05:07.260 Here you'll learn how to use variables. 05:07.300 --> 05:07.740 Okay. 05:08.300 --> 05:09.460 So good. 05:09.460 --> 05:12.100 Thanks for watching and I will see you in the next lecture.
