WEBVTT 00:02.120 --> 00:06.630 Hello and welcome to this tutorial from this tutorial, we understand. 00:06.920 --> 00:09.120 No indexing and selection. 00:09.380 --> 00:11.120 Let us begin with the basics. 00:11.990 --> 00:19.850 First, we have to import the library import numpty as and. 00:23.060 --> 00:32.300 Now create an ad A and B dot at age 10, Comac 21. 00:36.440 --> 00:40.970 Take the elements in this array, numbers from 10 to 20. 00:43.080 --> 00:50.890 Let us understand, indexing first typed the name of Eddie here V how to select No.15. 00:51.430 --> 00:56.230 Let us take the index location zero one, two, three, four, five. 00:56.240 --> 00:58.070 You for you. 01:00.270 --> 01:01.140 Fifteen. 01:01.770 --> 01:11.120 No, we will select the numbers from 10 to 14 by the name of Eddie Index zero two for you. 01:15.130 --> 01:20.860 Great numbers, strong, 10 to 14, upper bound is excluded here. 01:21.370 --> 01:23.650 Zero, one, two, three, four. 01:24.280 --> 01:27.460 We have specified indexed for you as a part bound. 01:28.240 --> 01:30.880 That is 415 and it is excluded. 01:32.440 --> 01:36.120 Now, suppose we have to select all the elements from this number. 01:36.490 --> 01:48.100 Well, to do that, we have to specify from index to then call execute all the numbers from Towill up 01:48.100 --> 01:48.790 to end. 01:50.530 --> 02:00.190 Now, suppose we have to select all the numbers of 215 to do that type name of the Eddie Colon Index, 02:00.190 --> 02:01.330 location six. 02:03.900 --> 02:05.730 All the numbers up 215. 02:06.640 --> 02:10.360 So this is all about the indexing and selection in array. 02:12.130 --> 02:15.100 Let us understand about the broadcasting values. 02:30.210 --> 02:32.100 Take the elements in Eddie. 02:35.750 --> 02:39.710 No broadcast to do that type edit name. 02:41.490 --> 02:45.890 Indexes from zero to for you is equal, 200 executed. 02:47.170 --> 02:48.480 Now take the eddy. 02:50.580 --> 02:54.000 You can see here foot five elements are a hundred. 02:54.810 --> 02:59.040 So using the broadcasting, we can change the elements in an array. 02:59.970 --> 03:01.650 No, really find this at a. 03:04.230 --> 03:05.640 ENPI Dot Huddinge. 03:09.200 --> 03:10.770 David Guama, 21. 03:13.840 --> 03:14.950 Take this, Eddie. 03:16.890 --> 03:17.550 Great. 03:19.390 --> 03:26.200 Now, take this slice of this, Eddie, elements from index zero to six. 03:28.830 --> 03:30.810 Save this in a variable. 03:33.270 --> 03:34.260 At Eddie. 03:39.400 --> 03:40.300 Staple here. 03:43.110 --> 03:43.630 Great. 03:45.290 --> 03:46.850 Now, take this variable. 03:49.490 --> 03:51.440 Numbers from 10 to 15. 03:52.370 --> 03:55.130 No use broadcasting on this variable. 03:57.020 --> 03:58.230 Slice at a. 03:59.990 --> 04:03.020 All the elements is equal to ninety nine. 04:06.380 --> 04:07.660 Take this variable. 04:09.740 --> 04:11.920 All the elements are 99. 04:13.100 --> 04:14.270 No joke or regional. 04:14.370 --> 04:14.870 Eddie. 04:18.050 --> 04:23.920 Here to let us understand this first, we have defined an eddy. 04:24.230 --> 04:25.630 This one, a R ah. 04:26.120 --> 04:30.820 These are the elements in this eddy from number 10 to 20. 04:31.580 --> 04:39.350 Then we have taken a sleighs that is from index zero to six and we help broadcaster this variable slice 04:39.390 --> 04:42.220 and dice score a R with 99. 04:42.890 --> 04:46.250 So all the elements in this variable are replaced. 04:46.880 --> 04:52.760 But when we replace all the elements in a sleigh's, the ordinal eddy is also changed. 04:53.860 --> 04:57.370 That means data is not copied in this variable. 04:57.580 --> 05:00.730 It is just a view of original at a number. 05:00.760 --> 05:03.190 Does that to our memory issues. 05:04.090 --> 05:05.500 We can make a copy. 05:05.630 --> 05:10.050 Also, let us see how you define a variable. 05:10.580 --> 05:15.280 Edit underscore copy is equal to or regional at a dot. 05:15.850 --> 05:16.460 Copy. 05:21.410 --> 05:22.670 Now, take this at a. 05:24.720 --> 05:26.700 Same as orignal at a. 05:27.690 --> 05:29.490 No broadcast this, Eddie. 05:32.960 --> 05:34.180 Name of the Eddie. 05:35.810 --> 05:38.200 All the elements in the 200. 05:41.790 --> 05:43.080 Now, take this at eight. 05:45.950 --> 05:46.880 We have to take this. 05:46.970 --> 05:47.480 Eddie. 05:51.210 --> 05:52.700 All the elements are handed. 05:52.920 --> 05:53.430 No. 05:54.490 --> 05:55.730 Now, take the copy. 06:00.750 --> 06:03.780 All the elements are the same as previous one. 06:04.230 --> 06:06.720 So there is no effect on this copy. 06:07.620 --> 06:09.390 Let us see one more example. 06:10.160 --> 06:13.160 Redefine this at a ENP dot. 06:13.430 --> 06:14.070 Arrange. 06:18.370 --> 06:19.070 Zero karma. 06:19.230 --> 06:19.840 Live on. 06:25.610 --> 06:27.410 Numbers from zero to 10. 06:28.610 --> 06:30.050 Now take a slice. 06:34.000 --> 06:34.520 Eddie. 06:37.340 --> 06:39.380 Indexed location zero to five to. 06:43.180 --> 06:44.250 Jake, this displays. 06:47.820 --> 06:48.380 Great. 06:49.070 --> 06:53.030 Zero, one, two, three, four, no broadcast. 06:57.250 --> 06:58.890 Select all the elements. 07:07.950 --> 07:10.170 No, all the elements are 100. 07:12.380 --> 07:13.880 Take additional, Eddie. 07:17.590 --> 07:19.870 First, few elements are changed. 07:20.800 --> 07:22.300 Now make a copy. 07:24.380 --> 07:31.370 At HCB to name off the air a copy. 07:35.960 --> 07:37.130 No broadcast. 07:41.570 --> 07:42.650 All the elements. 07:43.830 --> 07:44.630 200. 07:47.310 --> 07:48.360 Take this, Eddie. 07:53.350 --> 07:55.250 All the elements are 200. 07:55.360 --> 07:58.290 No, no Jake or regional Eddie. 08:00.320 --> 08:00.930 Same. 08:01.110 --> 08:01.960 No change. 08:03.050 --> 08:11.390 Let us understand this again, when we take a slice of an eddy like this, then it is just a view of 08:11.540 --> 08:12.420 regional eddy. 08:13.070 --> 08:18.100 Whatever changes we will do in this eddy will be reflected in orignal eddy. 08:18.670 --> 08:21.800 To a word that we can do this. 08:22.010 --> 08:24.400 We can take a copy of this Eddy. 08:25.280 --> 08:31.700 So this tutorial NCR, let us revise what we have learned in this tutorial here. 08:31.700 --> 08:35.230 We are understanding, indexing and selection in numpty. 08:35.840 --> 08:37.820 It is very similar to the lists. 08:40.590 --> 08:46.170 Then Vho understood broadcasting devalued to broadcast, devalued velho to light. 08:46.200 --> 08:51.850 Name of the A then type the index locations and specify a number. 08:54.620 --> 08:57.680 And at the end, V.L. understood how to use Kopi. 08:59.060 --> 09:00.200 The copy mattered. 09:01.160 --> 09:03.170 So despite ended Odille NCA. 09:03.740 --> 09:05.660 I will see you in the next one. 09:05.950 --> 09:07.780 buildOn Happy learning.
