00:14Welcome back, and peace be upon you. Now we'll continue our discussion in Num Bye and see how we can do slicing.
00:22The rules we follow in NumPy to perform slicing are the same rules we followed in Python when performing slicing.
00:29Hey, if you've forgotten these rules, I've put the link to the slicing video here in this notebook.
00:37You can go to the Python course on the Anteo Demi channel and check out this video.
00:45And I will also put this link to this video in the description.
00:53You can go there, and there will also be a link to the GitHub where this notebook is located.
01:00Okay, let's see how we can do slicing. First, we need to start with slicing.
01:07But first, we need to see what the slicing rules are. We have two rules, we have start and stop, and we have start.
01:14Stop and step
01:15Okay, let's see how we can apply them now. Here, I have a single-dimensional array.
01:22I did several slicing operations, let me run a run and we'll check the result together. Now here I took
01:28My ari and I sliced from zero to three, now the three will always be a stop, it will always be minus
01:35One will give me the result from zero to two, meaning the dragon, the six, and the eight. Here, I got the dragon, the six, and the eight.
01:44The same applies if I want to slice from Index 2 to Index 5; it will start at 8 and then proceed to 4.
01:52Then at nine it will stop at index 4 because 5 minus one will stop at index 4, so it will show me eight and four.
02:01and nine
02:01I can also use the two dots above each other to copy the file, just like it appears here.
02:07I can also use the stomp function; for example, I made a stomp here from one to seven, and then I make a stomp two.
02:15Okay, here I start with the zero shot, then the six, then the eight, then the four, then the nine, then the five, and it gives me six, four, and five.
02:26I can do the same thing now. As we know, a referral starts at the large index and ends at the small index.
02:36And the index for the dragon needs to be given what plus one. Now here I started from the six, which will be the one that
02:45I have one here, why? Because my index number is six here.
02:51Zero, one, two, three, four, five, six, so the two will be two plus one, so it will be three, so it will start with six, then five.
03:03Then what?
03:05Four, then three, so it will take one, five, nine, and four. If you also put seven here, it will give you the same result, no problem.
03:14But what
03:15We're putting it as a six, so whether it's a six or a seven, it'll give you the same result. Okay, now we'll also do the negative slicing.
03:26Negative slicing, like regular negative slicing
03:30Hey, for example, here I put several negative slicing options. Let's run a run and see what the result is. Now here I am
03:37I want to take from -7 to -4
03:40Okay, minus four minus one will give me minus five, so I want to start from minus seven to minus five, which is the minus.
03:47Seven, which is the dragon, and minus six, which is the six, and minus five, which is the eight.
03:53So, it gives me the same thing: the two, the six, and the eight. Here, I made a minus five, then a minus two, then a minus two, and one will stop at the minus.
04:02Three, so we start from minus five, which is eight.
04:05Then the minus 4, which is
04:08The four will stop at minus
04:103, which is nine
04:12It will give me 8, 4, and 9
04:14Just like he gave me here
04:16And we can also use
04:18The status is here, I want to start.
04:20From -7 to -1
04:22In STAP 2, will he take
04:24What is the first thing? What is the minus 7?
04:26Which is the dragon, will do
04:27Stab splits the six and takes
04:30The eight will split the four and take
04:32Nine and then
04:33He'll shoot the five, but he won't take anything.
04:36One, yes, why?
04:37Because we are minus 1
04:39Minus 1 will stop at minus
04:412 Valmence 2 done
04:44Stab, so he won't take it.
04:45What will I get?
04:47Dragon
04:50And the eight
04:51And the nine is good, that's for
04:54For the last thing, I can also
04:56Do a reverse here now
04:58I told Minus 1 of course
05:00In reverse, we start with the index.
05:02The large one is minus 1
05:04Minus 5 and degenerate
05:06Minus 1, hello, I'm here
05:08I took the minus 1, which is one.
05:10after
05:11Take the five and the nine
05:14He stopped at four because
05:15Minus 5 plus
05:181. Where will it stop at the minus point?
05:20Four, so he'll give me
05:22The Reverse
05:22okay
05:24I'm just now looking at De Ari
05:26First thing in 2D ARI
05:27To do slicing, we need
05:29What do we define?
05:30The raw material we want to work with
05:32slicing
05:32So, are you here?
05:34What did you do?
05:35Hi, I did
05:36Slicing kit
05:38High to Dimension
05:39Show
05:40Let's make it a run
05:41Hello, first thing I did was take this two-dimensional
05:43Show
05:44I took the first thing
05:46Raw Zero
05:47Which is this
05:48And I want to do slicing
05:49From one to three
05:51So, I prefer 72
05:52Stop at three minus two
05:55He'll stop at three.
05:56So he gives me seventy-two and three
05:58Same thing here
06:00I want to start making a copy
06:02For the second raw
06:04So here I put the index
06:06The second Raw followed
06:07Which is the one
06:08Then I put two dots on top of each other
06:10As you can see
06:11The Cuban gave me this ro
06:14We too
06:16We can do
06:17what
06:17We can do
06:18Step L
06:19Yes
06:20To De Ari
06:21For example, I am here
06:22I want to do
06:22Step L
06:24In the third Raw
06:26Which is
06:26The index followed it
06:28dragon
06:28What did you say?
06:30From zero
06:30Yes
06:31I put the index
06:32I followed this story
06:33And then
06:34Take
06:35Yes
06:36slicing
06:37On the Columns
06:38From zero to three
06:39And I put that
06:40Step Dragon
06:41He will take
06:42I have
06:42thirty-three
06:43Hayooqah
06:44Failure
06:44The eight
06:45And he will take
06:46The seven
06:47Because
06:48Three minus
06:48one
06:49He will give me
06:50dragon
06:50So he will stop
06:51when
06:51Monday
06:52Index
06:53dragon
06:53Which is
06:54The seven
06:54He will give me
06:55thirty-three
06:56and seven
06:56And what else?
06:57also
06:57I can
06:58Work
06:58Reverse
07:00Now I want to do
07:00Reverse
07:01For the fourth
07:03Which is
07:03Index
07:04I followed him
07:04three
07:05I put it here
07:06Index
07:06The fourth Ror followed
07:07And then
07:08I started
07:09In the index
07:09The large
07:10for the Landix
07:10The small
07:11And I put
07:12Mines
07:13one
07:13I loved him
07:14out of three
07:14Which is
07:16The nine
07:16And then
07:18Here
07:18Zero
07:18And then
07:19One
07:19why
07:20Because
07:21Zero
07:21plus
07:21one
07:22He will give me
07:23one
07:23So he will stop
07:24when
07:24Index
07:25one
07:25Hello, like this
07:27hopefully
07:27It should be clear
07:28Image
07:28Hello, here
07:29We will stop
07:29God willing
07:30In the next video
07:31We will continue
07:32in
07:33The
07:34Just now
07:35Ariz
07:35And then
07:36also
07:37We'll see
07:37how
07:37We can
07:38We work
07:38Slicing
07:39in
07:39The
07:40Thanks
07:41your
07:41See you
07:42In the video
