1
00:00:00,510 --> 00:00:04,890
We can access a wide range of characters using slicing

2
00:00:07,710 --> 00:00:11,550
if we want to cut a substring from a string.

3
00:00:11,550 --> 00:00:14,320
This is known as String slicing.

4
00:00:14,430 --> 00:00:23,890
We can access a range of items in a string by using the slicing operator colon and this is how the syntax

5
00:00:23,890 --> 00:00:24,460
was like.

6
00:00:24,460 --> 00:00:36,120
Thing looks like say for example I want to retrieve the characters you in the from these string country.

7
00:00:36,190 --> 00:00:45,640
This is how we construct the slice the first index number is where these lines start.

8
00:00:45,790 --> 00:00:53,680
So we want to begin the slicing at the character you which is inclusive.

9
00:00:54,070 --> 00:01:00,550
And the second index numbered is where these lies and exclusive.

10
00:01:00,580 --> 00:01:08,190
So when I say the second index number is 6 these lighting stops here

11
00:01:11,150 --> 00:01:14,350
and it is going to exclude the character.

12
00:01:14,350 --> 00:01:14,620
Why.

13
00:01:14,630 --> 00:01:17,830
That is the index number 6.

14
00:01:17,990 --> 00:01:26,570
So the output would be you in T.

15
00:01:29,860 --> 00:01:34,860
Let's check these lighting functionality in the Jupiter non book.

16
00:01:35,050 --> 00:01:42,730
Let's define a string and like we discussed we will

17
00:01:45,970 --> 00:01:55,000
we will slice the string from the index to up to index six exclusive.

18
00:01:55,100 --> 00:02:10,270
So as you can see here the original string is d r 1 has been sliced from index to 2 to index 6 excluding

19
00:02:11,940 --> 00:02:12,300
now.

20
00:02:12,300 --> 00:02:20,010
Say for example I would want to retrieve all of the characters in the string then I could give something

21
00:02:20,010 --> 00:02:21,690
like this.

22
00:02:21,690 --> 00:02:29,490
If we remove both of the indexes and include the colon in between these great brackets this would retrieve

23
00:02:29,520 --> 00:02:31,520
all of the characters in this string.

24
00:02:32,580 --> 00:02:39,960
So this would give me on the characters.

25
00:02:40,150 --> 00:02:54,320
Now if I want to retrieve say for example characters up onto index code that gives I can leave the first

26
00:02:54,440 --> 00:03:13,840
index as blank or Z2 and then the output would be C or U N because this exclude the index numbered form

27
00:03:14,190 --> 00:03:27,820
which is d next if I want to retrieve the characters beginning from the card index number.

28
00:03:27,830 --> 00:03:37,100
In that case I can give the first index as 2D and leave the second index as blank.

29
00:03:37,100 --> 00:03:44,160
This would give me t y.

30
00:03:44,460 --> 00:03:49,560
So let me see this in the in the Jupiter note book.

31
00:03:51,770 --> 00:04:01,060
So in order to retrieve all of the characters in this string within the square brackets I include the

32
00:04:01,060 --> 00:04:15,280
colon that the paused and the second index numbers as blank so this retrieves all the characters.

33
00:04:15,280 --> 00:04:17,600
Now save for example exam.

34
00:04:23,510 --> 00:04:29,280
I want to retrieve all of the characters beginning from the index.

35
00:04:29,390 --> 00:04:30,380
Three.

36
00:04:30,840 --> 00:04:46,720
So I would give you the index three here as the first index number and leave out the second index number.

37
00:04:49,770 --> 00:05:00,140
So slicing begins with the index number three and retrieves all of the characters until the end of the

38
00:05:00,140 --> 00:05:01,900
string.

39
00:05:01,900 --> 00:05:16,660
Say now I want to retrieve the characters beginning from the zero 8 index up until the index by so nutcase

40
00:05:18,750 --> 00:05:29,400
I am going to leave out the first index number and enter the second index number six and instead of

41
00:05:29,410 --> 00:05:33,330
four leaving the first index number as blank.

42
00:05:33,390 --> 00:05:41,440
You can also enter zero meaning you're on to the tree beginning from the zero it index.

43
00:05:41,610 --> 00:05:44,690
So the result remained the same.

44
00:05:44,700 --> 00:05:49,180
Another feature of slicing is extended slicing.

45
00:05:49,320 --> 00:05:59,400
Say for example I would like to retrieve every other character the index number zero up until the index

46
00:05:59,400 --> 00:06:00,360
number five.

47
00:06:01,230 --> 00:06:04,230
So I want to retrieve the characters see

48
00:06:07,170 --> 00:06:09,100
and deep.

49
00:06:09,250 --> 00:06:17,530
So how do we do that and this is this index for the extended slice.

50
00:06:17,620 --> 00:06:25,310
The first index numbered repos to where the slicing begins.

51
00:06:25,460 --> 00:06:38,020
The second index number refers to where the slicing ends and deterred but amateur hood is known as a

52
00:06:38,020 --> 00:06:39,030
straight.

53
00:06:39,070 --> 00:06:46,550
And this refers to how many characters to move forward after the first character is retrieved from the

54
00:06:46,550 --> 00:06:47,540
string.

55
00:06:47,560 --> 00:06:55,840
So in either case we are going to retrieve every other character every second character from the first

56
00:06:56,140 --> 00:06:56,770
character.

57
00:06:58,000 --> 00:07:07,820
This would give me the output as I see you deep by default the.

58
00:07:07,850 --> 00:07:19,000
Is this parameter would be 1 which means it retrieves all of the characters beginning from 0 with index.

59
00:07:19,000 --> 00:07:25,980
Let's go see how the extended slice works in the Jupiter known book.

60
00:07:26,050 --> 00:07:28,290
So this is a string.

61
00:07:28,360 --> 00:07:29,470
String 1.

62
00:07:30,280 --> 00:07:39,160
And I'm going to begin the slicing from index 0 so begins things.

63
00:07:39,180 --> 00:07:40,710
It is index 0.

64
00:07:40,710 --> 00:07:44,270
You can either enter 0 or leave it as a blank.

65
00:07:44,550 --> 00:08:00,510
The second index number is 5 so these lighting and add 5 character play and the third parameter to this

66
00:08:00,510 --> 00:08:07,350
trait parameter and we are going to enter 2 which means we are going to retrieve every other character.

67
00:08:08,570 --> 00:08:10,750
So executing.

68
00:08:10,880 --> 00:08:12,860
So this is the output.

69
00:08:12,860 --> 00:08:15,990
Let us see.

70
00:08:16,110 --> 00:08:20,040
I want to retrieve all of the characters between 0 and 5.

71
00:08:21,070 --> 00:08:32,100
And I'm going to enter these tried but amateur as one execute so it doesn't read all of the characters.

72
00:08:32,120 --> 00:08:46,400
Now let us skip over these trade parameters so enter your first and second index numbers so the output

73
00:08:46,460 --> 00:08:48,390
is the same as this.

74
00:08:48,410 --> 00:08:51,620
Then this trade parameter has been given as one.

75
00:08:51,650 --> 00:08:59,780
This means Python defaults to these tried of one so that every character between the two index numbers

76
00:08:59,870 --> 00:09:00,640
is retrieved.

77
00:09:01,760 --> 00:09:03,170
This is about slicing.
