00:14Welcome back, and peace be upon you. Now let's continue our conversation about sleep.
00:19Okay, let's see how we can do indexing. Of course, sleep is next.
00:25These rules are the same rules we learned in Python courses when
00:31We worked on indexing the strings, the lass, and the tabl. They are the same rules.
00:37Python followed indexing. Now, if you don't know what this rule is, uh...
00:44I forgot this link, I put the link to the video here first, the one that says
00:51About indexing. You can go to this link and watch the first video.
00:55About indexing rules. We'll continue in the remaining videos. Of course.
01:01This video is available in the Python Courses section of the channel.
01:05Follow us. It's included in Part One of Python Core. Now, I'm...
01:10Here's what I've put inside this notebook. You can open it if you want.
01:17This notebook. This notebook will be on [website/platform name].
01:21You can go to [website/platform name] and fork this notebook and [do something].
01:28On this link. I'll also put a little something for you.
01:33Put this link in the comments of this video. Okay, now this
01:39Badlas B, if you want, if you've forgotten the rules, the indexing print.
01:43First, we need to start; we need to start in order to create the indexing.
01:47For single-dimensional arrays, first we import the data. Then
01:52Here I've identified my index. Now, as you can see, it's there.
01:57Four items. I want to get the index zero and the index
02:01Three. Index zero will produce a dragon, and Index three will produce what? Four.
02:06Okay, I ran it. I got two and four. Same thing with indexing.
02:12The negative index, I want to get out, I am the one who is ...
02:17Minus one and the item that you curse Minus four. The artifact
02:21The minus one will be four and the two. I'm whipping, I want to get four.
02:27And the dragon. Minutes too, as you can see,
02:32The Single Dimension Array is a Straight Forward array.
02:35It means like you do
02:36Indexing for Tuple, List, or String
02:39It performs indexing
02:41For Single Dimension Array
02:42Here too
02:44As we said before
02:46It's something we can do
02:48What do we use the Lens Function with in an Array?
02:50Now, when I use the Lens Function
02:52With the array or
02:54What do I get for a Single Dimension Array?
02:56It shows me the number of items inside this array
02:58He gave me four because I
03:00I have four items here
03:02Okay, what about the Single Array?
03:04As we said, it's Straight Forward
03:06Okay, let's start now.
03:08Two Dimension Array
03:09Now the Two Dimension Array will be different because we will have
03:12Rose and Columbus
03:13That's why we need to put
03:15When we do indexing
03:17The Index is followed by the Row first.
03:19Then we set its index.
03:22Column
03:23Let me show you how
03:24Let's run this slug
03:26We'll look at the results and then explain that they
03:29One by one
03:29Now I want to leave
03:31In the First Row
03:33Of course, as we said first, we put the Index
03:36The Row followed him. Now this is it.
03:38The first row whose index
03:40Zero, just like I put it here
03:41Zero
03:42The First Element, which is seven
03:46Also the Index
03:47Zero followed, I put zero
03:50I put its index in the row, which is
03:51Zero and Index followed it
03:53The column is zero
03:55So that's how I got seven
03:57Now, as you can see
03:59It's in NumPy
04:02When we do indexing
04:03It's different when we do the indexing.
04:05For Nested List
04:08or Nested Tuple
04:09When we had a Nested List
04:11We used Hayk
04:13This is how we do indexing.
04:15For Nested List
04:17While in NumPy we just put a comma
04:20Between Indexing
04:21This is Indexing in NumPy
04:23Also, if we go out
04:25The second element in the first row
04:27What I want to reveal
04:29Second Element
04:30Which is 72
04:31In the First Row
04:33I want to put zero and what's one?
04:36Zero One
04:37The third element in the second row
04:39I want to get this out; I have the Second Row.
04:41Which is its Index, one
04:44The Third Element
04:45The Index was followed by a dragon
04:47And what else do I want to go out with?
04:49The Fourth
04:49The second element in the fourth row
04:52Which is the number 1 I have
04:54The index of the fourth row is three.
04:56The index following 1 is one.
04:59So I get one
05:01Of course, I can do what too.
05:03As much as I can work
05:03Negative Indexing
05:05Same thing
05:06Hello, here I have the same array.
05:09I want to go out
05:10First Element in First Row
05:12Hi, I have the First Row
05:15Which is its Index.
05:16Minus one
05:17The first element followed by the index
05:21Mins three
05:21So what do I get?
05:23seven
05:23Hey, we're running
05:24Hey, I got seven.
05:26Same thing
05:27Second Element in the First Row
05:28Which is 72
05:30The Index will be
05:32For Row
05:33Mins 4
05:33And for the Second Element
05:36Mins 2
05:37So I get 72
05:38Same thing
05:40Hello, what can I put?
05:41I don't put Negative
05:42Positive Indexing
05:44Just like I did here
05:45Set Positive Indexing for Row
05:48Which is what?
05:49Here I have
05:51Second Row
05:52Which is this
05:53What
05:55And put one mini
05:56Which is 6
05:57Item
05:59Index
05:59The 6 followed
06:00It came out to me
06:01What did I get? 6
06:02Same thing
06:03I can also
06:04Put the rows
06:05By
06:06Negative
06:07Negative
06:08Sorry
06:09And I put
06:10Column
06:11Positive
06:12I want to go out
06:13Second Element in the Fourth Row
06:15Which is 1
06:16Index
06:17Followed the Fourth Row
06:18Which is
06:18Minus one
06:19and the Index
06:20Followed the column
06:21Which is one
06:22I got one
06:23That's me
06:23By working
06:24Indexing
06:25in
06:252D Arrays
06:26Also now
06:28We know
06:28When we talked
06:29In the previous video
06:31When we want to use
06:32LEN function
06:33If we use it
06:35With the array
06:35It will show us the number of rows
06:37So if I want to do
06:39Check
06:40number
06:41Items
06:41The one in the column
06:42What should I do?
06:43Using Indexing
06:44Just like I did here
06:45phonograph
06:45LEN
06:46Array
06:49blow
06:493
06:50And I put a piece of my body
06:51He reviewed the number of items
06:53The one in the row
06:540
06:54I put the Index
06:56Zero Edition
06:56In this way
06:57Row Edition
06:59Just 0
06:59In this way
07:00And it shows me the Index
07:02what?
07:023
07:03If I had done it, I wouldn't have put the Index.
07:05It will show me the number of rows.
07:07In this array
07:08If you put the Index
07:09It gives me the number of columns.
07:11In this array
07:12So that's how I can use LEN
07:14Function
07:15And as much as I can work
07:16negative
07:17and positive
07:19indexing
07:20In 2D Array
07:21Now we'll stop here
07:23God willing
07:23In the next video
07:25We will continue
07:25And we talk about
07:273D Arrays
07:29See you in the next video!
