1
00:00:05,800 --> 00:00:06,630
Hey everyone.

2
00:00:06,950 --> 00:00:12,520
So in the last review we are also done with the accessing of elements now in this video we are going

3
00:00:12,520 --> 00:00:13,070
to do.

4
00:00:13,060 --> 00:00:18,250
Conditional selection that is something like what if you want to access the elements that are greater

5
00:00:18,250 --> 00:00:22,900
than do here or because it is three greater than three in this table.

6
00:00:23,380 --> 00:00:29,890
So we will do something like this the F greater than three you will get a table of boolean values in

7
00:00:29,890 --> 00:00:35,830
which those values are who are greater than three not only equal just greater than three like for here

8
00:00:36,390 --> 00:00:40,300
will get through like this be all have greater than three.

9
00:00:40,300 --> 00:00:46,450
So all here are true and this is what is known as condition selection.

10
00:00:46,450 --> 00:00:51,760
And one more thing What if you want to have the values that are greater than three then just pass this

11
00:00:51,760 --> 00:00:58,840
condition like the index to the if you will get all the values that are greater than three here in this

12
00:00:59,260 --> 00:00:59,990
table.

13
00:01:00,160 --> 00:01:04,010
Informal floats and all the other values are known.

14
00:01:04,090 --> 00:01:08,320
That is for none after that.

15
00:01:08,830 --> 00:01:11,220
This is all about the condition selection.

16
00:01:11,320 --> 00:01:17,620
Just a few basic and little concepts like what if you want to have the elements in any particular column

17
00:01:17,650 --> 00:01:19,580
that are greater than three.

18
00:01:19,690 --> 00:01:26,580
So you need to just pass that particular in column to that death.

19
00:01:26,640 --> 00:01:33,630
Now here you will not get the elements like 5 9 7 when you run that one you will get a table something

20
00:01:33,630 --> 00:01:35,150
like this one.

21
00:01:35,640 --> 00:01:42,870
This will show all the rows whose values for that particular column satisfy the condition like here.

22
00:01:42,870 --> 00:01:46,820
The B row this has fine that is greater than three.

23
00:01:46,830 --> 00:01:49,160
So here we have beetle not a.

24
00:01:49,300 --> 00:01:52,630
Then we have C 9 that is greater than three then three.

25
00:01:52,640 --> 00:01:59,370
It it's not greater than three so we do not have this one then E then Haber here we have this one if

26
00:01:59,370 --> 00:02:07,380
you want to have any particular column like I want to have W and X then you just need to do something

27
00:02:07,380 --> 00:02:14,940
like pass here on the set of these brackets inside backwards you will write something like I want to

28
00:02:14,940 --> 00:02:23,610
have W and X in capital then you will get only this one.

29
00:02:24,060 --> 00:02:32,550
So this is how you can get any particular part of the table you want to if you remove this one and these

30
00:02:32,550 --> 00:02:39,040
outside you will only get w the values we are talking about that is 5 9 and 7.

31
00:02:39,930 --> 00:02:46,290
So that's how you can have any particular value in any particular table if you want we'll do this one

32
00:02:46,290 --> 00:02:54,800
like greater than eight sorry this eight you will get only nine.

33
00:02:54,940 --> 00:03:02,200
So this is all about the condition of selection and I hope you understand this one also here.

34
00:03:02,320 --> 00:03:09,100
Make sure that by passing more than two columns or 1 2 X is more than two columns pass double brackets

35
00:03:09,220 --> 00:03:10,520
instead of single vote.

36
00:03:11,230 --> 00:03:13,310
So we are done with this one.

37
00:03:13,340 --> 00:03:13,890
No.

38
00:03:14,090 --> 00:03:20,380
A little more basic concept that is what if you have different conditions or we can say that more than

39
00:03:20,380 --> 00:03:23,250
one conditions then how we can do them.

40
00:03:23,500 --> 00:03:29,510
So far more than one conditions in operators also maybe you remembered we have done something like and

41
00:03:29,510 --> 00:03:33,980
an order and this one and this one.

42
00:03:34,510 --> 00:03:44,830
So we will use these two in case of multiple conditions like something if I want to have in w that dot

43
00:03:46,700 --> 00:03:49,390
like greater than three.

44
00:03:49,700 --> 00:03:51,980
That is we take greater than three.

45
00:03:52,430 --> 00:04:02,720
And if you want to have something like the values that are greater than two in Z then we will do something

46
00:04:02,720 --> 00:04:14,240
like If you do this thing like and then here you will bus the F then he Z greater than two and you will

47
00:04:14,240 --> 00:04:17,480
pass this one completely to the.

48
00:04:19,070 --> 00:04:24,380
They have to get the values only instead of two unfolds.

49
00:04:24,380 --> 00:04:25,670
So here you will get at it.

50
00:04:26,720 --> 00:04:33,470
And the reason for that added is not the any syntax because this syntax is completely fine.

51
00:04:34,010 --> 00:04:40,390
But the thing here is you cannot use and or here.

52
00:04:40,820 --> 00:04:49,850
One more thing make these in parentheses or that there will be a little more differentiated.

53
00:04:49,850 --> 00:04:55,550
So the thing here is you cannot use and and order here you need to use this for.

54
00:04:55,590 --> 00:05:02,110
And hey you will get this one b those who are greater than t in W so greater than two in the blood.

55
00:05:02,110 --> 00:05:05,830
Five nine tenths heaven and greater than two in Z.

56
00:05:05,870 --> 00:05:13,430
So out of these three now because other two are eliminated already so out of 8 2 and 0 which is greater

57
00:05:13,430 --> 00:05:15,750
than 2 that is 8.

58
00:05:15,770 --> 00:05:23,780
So here we get B only if you do something like greater than zero in the blue or the values are greater

59
00:05:23,780 --> 00:05:32,810
than zero and instead just the values that are greater than three and you do this one you will get all

60
00:05:32,810 --> 00:05:37,430
the values in the blue because every value is greater than zero.

61
00:05:37,550 --> 00:05:43,290
And in Z only the values that are greater than three that is for 8 and 6 foot 8 and 6.

62
00:05:43,400 --> 00:05:51,200
So that's all you can do that one if you want to use all here you will get this one either this condition

63
00:05:51,200 --> 00:05:54,520
is true or this condition is true all the things will happen.

64
00:05:54,710 --> 00:05:57,470
So that's why we have the complete data.

65
00:05:57,650 --> 00:06:04,760
If you do hear something like in the blog greater then like 9 because nothing is greater than 9 in there

66
00:06:05,360 --> 00:06:08,150
and in Z you make that greater than 3.

67
00:06:08,280 --> 00:06:14,150
You run that you will get all the values in Z that are created then three nickels why is not satisfying

68
00:06:14,150 --> 00:06:14,540
then.

69
00:06:14,780 --> 00:06:15,780
But we are using all.

70
00:06:15,860 --> 00:06:22,580
So if only one can satisfy we will get output but if you use something like nine here you will get an

71
00:06:22,580 --> 00:06:23,840
empty list.

72
00:06:25,550 --> 00:06:30,500
So there is all about the conditional selection and I hope you got the idea that what we have done here

73
00:06:30,800 --> 00:06:35,570
and we cannot perform that thing like this one.

74
00:06:35,570 --> 00:06:41,840
So we have done this with a numerical one so thanks for watching and we will continue in the next video.
