WEBVTT 00:01.000 --> 00:03.960 Okay, now our program is completed. 00:05.000 --> 00:15.440 Okay, but for learning Python, for understanding the Python better, I can use another way or another 00:15.440 --> 00:18.240 thing to create this part. 00:18.280 --> 00:19.080 Okay. 00:19.120 --> 00:19.760 Improve this. 00:19.760 --> 00:25.520 For example right here we're just using lists but I can use dictionary okay. 00:25.560 --> 00:30.320 So it is just for better understanding of dictionaries. 00:30.920 --> 00:38.320 So let's remove this part okay I will just remove it or I can comment this or I will remove it okay. 00:38.320 --> 00:39.000 So here. 00:41.120 --> 00:43.640 First we need to create an empty list. 00:43.640 --> 00:52.000 And then for each time that it is reading or getting a packet, we need to add that packet to the list. 00:52.000 --> 00:54.920 And it will create a dictionary for me. 00:54.920 --> 00:57.600 And later I can use dictionaries. 00:57.600 --> 01:05.160 Dictionaries has keys and values and I can use keys and values to print the result. 01:05.200 --> 01:05.560 Okay. 01:05.760 --> 01:06.520 Very easy. 01:08.840 --> 01:09.640 Let's do that. 01:09.680 --> 01:10.200 Okay. 01:10.240 --> 01:16.200 So here I am inside this function, which is called scan. 01:16.400 --> 01:18.680 I'm going to create a new list. 01:18.680 --> 01:23.320 Let's name it client underscore list. 01:23.360 --> 01:23.760 Okay. 01:27.560 --> 01:30.560 So it is going to be an empty list right now. 01:31.200 --> 01:31.600 Okay. 01:32.240 --> 01:34.880 Let's use for loop A for loop here. 01:34.920 --> 01:35.360 Okay. 01:35.920 --> 01:36.680 Element. 01:41.800 --> 01:44.880 Element in we had answered. 01:44.920 --> 01:45.320 Okay. 01:46.080 --> 01:46.640 In answer. 01:46.680 --> 01:51.240 Do you know that this answer variable is a list right now okay. 01:52.160 --> 01:55.080 So here I need to create two things. 01:55.120 --> 01:55.560 Okay. 01:56.320 --> 02:02.970 For at least one thing we are going to have the IP and also the Mac. 02:03.130 --> 02:05.290 So let's create a dictionary here. 02:05.610 --> 02:05.970 Okay. 02:06.330 --> 02:10.970 It's going to be client dictionary I'm going to name it client dict. 02:11.010 --> 02:14.330 It is equal to a dictionary. 02:14.370 --> 02:22.330 So this dictionary has a key with the key is going to be IP and it has a value. 02:22.490 --> 02:28.730 So the value is going to be for this one is going to be element okay. 02:33.090 --> 02:36.770 Dot the IP which is p.s.r.c. 02:36.810 --> 02:39.730 And also we have the Mac address. 02:39.770 --> 02:40.490 Okay. 02:40.530 --> 02:41.810 This is going to be the key. 02:41.850 --> 02:45.650 And the value for Mac address is going to be element. 02:48.090 --> 02:56.890 One dot h w is r c which is going to be hardware source for the Mac address. 02:57.250 --> 03:00.210 Okay now I have the client dictionary. 03:00.930 --> 03:08.810 And for each loop for each time that it is, uh, reading the packet. 03:08.850 --> 03:12.170 I need to add these to the list. 03:12.290 --> 03:13.930 So how can I do that? 03:14.610 --> 03:17.530 List has a function called append. 03:18.090 --> 03:19.050 So let's use that. 03:19.090 --> 03:19.290 Okay. 03:19.290 --> 03:21.050 We have clients list. 03:21.330 --> 03:24.050 Then let's use the function that it has. 03:24.050 --> 03:25.770 It calls append. 03:25.810 --> 03:34.730 This append will add okay this to the list for each of a loop for each time that it is getting a packet. 03:35.210 --> 03:43.490 So and then give the client dictionary okay for the first time it will come and read the element from 03:43.490 --> 03:44.850 the answer list. 03:44.890 --> 03:45.690 Okay. 03:45.730 --> 03:50.410 And then it will append that to the client list which is here okay. 03:50.450 --> 03:58.250 And then it come to read the second packet the third packet fourth packet and all the packet okay. 03:58.290 --> 04:01.370 So when it is finished you need to return that. 04:01.370 --> 04:03.650 So let's return it okay. 04:03.780 --> 04:07.100 Return client list. 04:07.420 --> 04:11.060 Okay, so now it is the first function that is doing its job. 04:11.460 --> 04:16.340 And you need to create another function to print the result. 04:16.580 --> 04:24.100 So let's create a function named print underscore result. 04:24.580 --> 04:25.020 Okay. 04:26.380 --> 04:32.220 So this is going to get uh something. 04:32.220 --> 04:37.540 Let's name it result list is going to be an argument okay. 04:37.860 --> 04:41.740 So here we need to print the IP mac address. 04:42.060 --> 04:44.380 And then going to the next line. 04:44.540 --> 04:54.460 And like that the thing that we have done it before okay we have IP okay at least three tab. 04:54.460 --> 04:58.580 And then what Mac address. 04:58.620 --> 05:02.300 Okay Mac address. 05:04.420 --> 05:10.180 And then go to a new line which is backslash n and something like this. 05:11.060 --> 05:11.500 Okay. 05:11.900 --> 05:13.780 Now it is the header okay. 05:13.820 --> 05:15.300 The header is completed. 05:15.460 --> 05:19.380 So now it is time to print the IP and the Mac address itself. 05:19.580 --> 05:21.780 So how can we do that. 05:21.780 --> 05:23.580 Again I'm going to use a for loop. 05:23.980 --> 05:28.180 Or I'm going to create a new variable called client. 05:28.460 --> 05:34.100 For client in we have the result list okay. 05:35.300 --> 05:37.740 And here I'm going to print that. 05:38.300 --> 05:42.340 So now this client is a dictionary. 05:43.020 --> 05:52.300 And here I'm going to print the IP for this and concatenate this with at least two tab. 05:55.300 --> 05:59.220 And again the Mac address. 05:59.580 --> 06:00.020 Okay. 06:04.940 --> 06:05.620 And. 06:07.380 --> 06:07.900 finished. 06:07.940 --> 06:10.340 Okay, so now it is time to. 06:13.220 --> 06:15.900 To call those functions. 06:15.940 --> 06:16.620 Okay. 06:16.660 --> 06:18.580 So here we have the scan function. 06:18.620 --> 06:19.540 Okay. 06:19.580 --> 06:23.940 And as you see we have the result list here. 06:24.180 --> 06:30.300 We need to, uh store this scan function into a variable. 06:30.340 --> 06:32.620 I'm going to name it scan result. 06:32.660 --> 06:33.500 Okay. 06:33.540 --> 06:34.940 So let's use scan. 06:34.940 --> 06:38.460 Underscore result is equal to this one. 06:38.820 --> 06:43.540 And then I am calling the print result function. 06:43.540 --> 06:48.500 And then giving it the scan result. 06:48.940 --> 06:52.500 And I think now it is completed. 06:52.580 --> 07:02.820 If I come back right here and re-execute this providing the password which is Collie and waiting a moment, 07:02.820 --> 07:08.590 you're seeing that we are having the same result this time with dictionary. 07:11.870 --> 07:16.190 I want to add a little some more of this dot. 07:16.590 --> 07:17.030 Okay. 07:18.870 --> 07:23.830 So it looks more beautiful now. 07:23.870 --> 07:25.710 I think it is better. 07:25.990 --> 07:31.950 So here you learn how to use one function using list. 07:31.950 --> 07:36.030 And also you learn how to use dictionaries okay. 07:36.070 --> 07:37.630 You create this program. 07:38.070 --> 07:41.710 And here we use two function to do this. 07:41.750 --> 07:43.230 So thanks for watching. 07:43.270 --> 07:46.070 And this section is completed. 07:46.150 --> 07:49.550 You created your network scanner and it is completed. 07:49.550 --> 07:51.110 It's working for all network. 07:51.150 --> 07:52.070 Okay. 07:52.110 --> 07:58.670 No matter if it is wired or wireless or Wi-Fi or anything, it is going to work for all networks. 07:58.870 --> 08:02.990 So for me it is a virtual network and wired. 08:03.030 --> 08:07.670 So thanks for watching and I will see you in the next section.
