00:00:02,500 --> 00:00:05,000
Friends, here we are going to discuss the last

3
00:00:05,000 --> 00:00:07,300
default data structure of your Python,

4
00:00:07,300 --> 00:00:09,000
that is set data structure.

5
00:00:10,000 --> 00:00:11,600
Let me open my terminal,

6
00:00:13,300 --> 00:00:17,500
and I'm entering into 'python' terminal, right. See if you want

7
00:00:17,500 --> 00:00:18,700
to define any set,

8
00:00:18,700 --> 00:00:24,000
let's say 'my_set={' with normal values.

9
00:00:25,700 --> 00:00:27,800
You can define any value, okay.

10
00:00:29,200 --> 00:00:31,700
See that, now I am printing my set.

11
00:00:31,700 --> 00:00:34,900
[no audio]

12
00:00:34,900 --> 00:00:37,300
So the way how you are giving,

13
00:00:38,400 --> 00:00:42,000
, but it is giving output as

14
00:00:43,300 --> 00:00:47,800
in ascending order, that means whatever the data you're providing

15
00:00:47,800 --> 00:00:52,300
it is not giving the same order. That means sets are called

16
00:00:52,300 --> 00:00:54,700
unordered collection of data.

17
00:00:55,400 --> 00:00:59,300
And if you give any data multiple times, if you give data,

18
00:01:00,600 --> 00:01:03,800
duplicates data or multiple times of data, suppose

19
00:01:03,800 --> 00:01:05,300
I have given 7, two times,

20
00:01:06,599 --> 00:01:11,500
so set will give unique data. Duplicates will be removed by

21
00:01:11,500 --> 00:01:13,300
default. That's it.

22
00:01:14,800 --> 00:01:21,100
Now if we convert your data into Boolean, 'True', because it is

23
00:01:21,100 --> 00:01:23,000
non-empty set, right?

24
00:01:23,500 --> 00:01:26,800
Let me define 'my_set' which is having a non empty,

25
00:01:26,800 --> 00:01:28,800
[no audio]

26
00:01:28,800 --> 00:01:29,900
sorry empty set.

27
00:01:30,500 --> 00:01:33,300
So guys if you want to define empty set you have to write

28
00:01:33,400 --> 00:01:36,400
a 'set()', because if you define direct straight

29
00:01:36,400 --> 00:01:38,500
forward curly brace that will become dictionary.

30
00:01:39,700 --> 00:01:42,600
Now print the type of your 'my_set'.

31
00:01:42,600 --> 00:01:46,500
[no audio]

32
00:01:46,500 --> 00:01:51,000
Now let me print Boolean of your 'my_set'. It is 'False' because

33
00:01:51,000 --> 00:01:52,100
empty set, right?

34
00:01:52,900 --> 00:01:55,400
So guys, this is the way how you can define your set,

35
00:01:56,500 --> 00:01:58,600
right, and how you can convert your set into Boolean,

36
00:01:58,600 --> 00:02:00,600
and what is the data you are getting when your set is

37
00:02:00,600 --> 00:02:05,600
empty. Let's say I'm having a list called 'my_list

38
00:02:07,000 --> 00:02:08,000
equals to,

39
00:02:08,000 --> 00:02:10,400
[no audio]

40
00:02:10,400 --> 00:02:16,300
you can convert this list into set, 'set(my_list)'.

41
00:02:16,300 --> 00:02:18,900
[no audio]

42
00:02:18,900 --> 00:02:22,300
That's it. In case you have any data multiple times

43
00:02:22,300 --> 00:02:27,400
in your list your set will give the unique data.

44
00:02:28,700 --> 00:02:29,700
That's it,

45
00:02:30,500 --> 00:02:35,600
and anyway it is ascending order, that means unordered collection

46
00:02:35,600 --> 00:02:37,300
actually, right. Fine.

47
00:02:37,900 --> 00:02:40,900
So if you want to see the different types of operations on

48
00:02:40,900 --> 00:02:43,400
your sets simply you can run this and you can see.

49
00:02:43,400 --> 00:02:50,400
[no audio]

50
00:02:50,400 --> 00:02:55,800
So, or you can do you know, let's say set 'a' is there in this way

51
00:02:56,800 --> 00:03:02,700
, and set 'b' is there in this way .

52
00:03:02,700 --> 00:03:05,600
[no audio]

53
00:03:05,600 --> 00:03:11,000
So I want to find 'a union b', right. 'a.union(b)'.

54
00:03:11,000 --> 00:03:14,400
See the output. 'a.intersection',

55
00:03:14,400 --> 00:03:17,600
[no audio]

56
00:03:17,600 --> 00:03:20,000
'intersection(b)'. That's it.

57
00:03:21,700 --> 00:03:25,200
Okay. So guys there are remaining operations as well,

58
00:03:25,200 --> 00:03:27,800
but on automation side no where we are going to touch this

59
00:03:27,800 --> 00:03:29,000
set data structure.

60
00:03:29,000 --> 00:03:33,300
If you are interested you can go and learn about your remaining

61
00:03:33,500 --> 00:03:37,800
operations on your sets. I've gone through only union, intersection,

62
00:03:37,800 --> 00:03:40,800
if you are interested about sets anyway, your mathematics

63
00:03:40,800 --> 00:03:43,600
sets operation only, right. You can go and see the remaining

64
00:03:43,600 --> 00:03:45,000
operations, okay.

65
00:03:46,600 --> 00:03:48,700
Okay guys, thank you for watching this video.
