WEBVTT 00:00.920 --> 00:01.280 Okay. 00:01.320 --> 00:08.760 After we learn something about tuple list, now it is time to learn about sets. 00:09.040 --> 00:10.880 Okay, what is it? 00:10.920 --> 00:14.840 Sets is also a it's a collection. 00:14.880 --> 00:15.960 Okay. 00:15.960 --> 00:22.680 It is not ordered means it doesn't have any index is not indexed. 00:22.680 --> 00:26.320 And in Python sets are written with curly brackets. 00:26.800 --> 00:29.360 For example I am going to create. 00:31.360 --> 00:32.520 It is equal to. 00:33.120 --> 00:40.920 You use curly bracket for this and then name of the some fruits like apple. 00:42.680 --> 00:46.120 What is the other one is like banana. 00:48.280 --> 00:51.800 And we have cherry okay. 00:53.400 --> 01:03.320 So now this is a set and it is not ordered means it doesn't have a index okay. 01:03.320 --> 01:04.280 It is not zero. 01:04.320 --> 01:05.120 This is not one. 01:05.120 --> 01:06.920 This is not two okay. 01:06.920 --> 01:13.880 So you cannot print these elements using the index because it is not ordered. 01:14.440 --> 01:21.190 So now let's use print and then use roids and save it. 01:22.830 --> 01:28.870 Open a new terminal and let's run this and see what is going to be happen. 01:28.910 --> 01:37.630 Okay city Python basic and let's use Python and sets.py. 01:37.670 --> 01:38.750 Hit enter. 01:38.790 --> 01:43.190 Now you see that it is printing all elements with curly brackets. 01:43.630 --> 01:46.830 And also those, uh, question marks. 01:46.870 --> 01:47.310 Okay. 01:47.950 --> 01:52.270 So how can I print, uh, element which is inside this. 01:52.310 --> 01:52.510 Okay. 01:52.550 --> 01:56.270 Each element again I need to use a for loop okay. 01:56.310 --> 02:02.390 To navigate through this fluids this set and then print all element. 02:03.150 --> 02:05.030 And let's go see that okay. 02:05.070 --> 02:09.830 For example again x in right. 02:11.470 --> 02:13.510 And the x okay. 02:13.510 --> 02:16.630 So this will come and start navigating through. 02:16.670 --> 02:16.950 Okay. 02:16.990 --> 02:19.590 So it will come and traveling through this. 02:19.630 --> 02:19.870 Okay. 02:19.910 --> 02:25.510 First it will print apple the next line banana in the next line cherry. 02:29.550 --> 02:31.570 See we Have cherry. 02:31.610 --> 02:34.850 We have apple and we have banana. 02:35.290 --> 02:40.490 So it is how it is working. 02:40.650 --> 02:41.050 Okay. 02:42.810 --> 02:46.290 And it is not ordered because of that. 02:46.290 --> 02:48.090 It is not printing first. 02:48.130 --> 02:48.570 This one. 02:48.610 --> 02:48.890 Second. 02:48.890 --> 02:49.410 This one. 02:49.450 --> 02:49.650 Third. 02:49.650 --> 02:49.970 This one. 02:49.970 --> 02:51.050 Because it is not ordered. 02:51.050 --> 02:57.170 So it is printing cherry, apple, banana and the other one. 02:57.210 --> 02:57.770 Okay. 02:57.810 --> 03:00.210 See this time it is apple, cherry, banana. 03:00.850 --> 03:03.530 And this time it is banana, apple cherry. 03:03.530 --> 03:06.530 Because of that it is not ordered. 03:06.530 --> 03:13.130 So it is how you can create a set and you can use it okay. 03:13.530 --> 03:14.730 Also we have. 03:16.930 --> 03:19.770 Other options for this okay. 03:19.810 --> 03:22.090 For example we can add element. 03:22.210 --> 03:27.330 We can remove element and we can update. 03:27.890 --> 03:30.370 We can print the length of the set. 03:30.690 --> 03:35.650 And a lot of things that we can do a lot of operation that we can do with set. 03:35.970 --> 03:44.290 But later we will see them with, uh, more examples through the course while we are using it into the 03:44.290 --> 03:46.130 real operation.
