Lecture 27: String Data Type

Nafees AI Lab

Strings are one of the foundational data types in programming and have a crucial role in machine learning. They are sequences of characters and can encapsulate textual data, making them incredibly versatile.

00:00Hello, welcome back.

00:05In the last lecture, we have discussed all the numeric data types.

00:12Now, we move our ordered sequence to move on

00:15and first we will learn string data types.

00:19I remember that this ordered sequence is ordered sequence.

00:23Now, we have ordered and unordered.

00:29First, I will tell you the definition of text book definition.

00:34It is a string sequence of characters.

00:39Now, if I write,

00:43Hello, I am a good guy.

00:46What are characters in a sequence?

00:51If I change sequence,

00:53then you will not understand meanings.

00:55Like I do.

00:58Does this make sense?

01:00No.

01:02If I change sequence,

01:05then the sentence has its meaning.

01:08Because it is ordered.

01:11It means that Python has a individual character

01:15where it exists.

01:18So, it will be traced.

01:20Okay.

01:21Now, we will go back to the string.

01:23Now, we will go back to the string.

01:24Now, we will go back to the string.

01:26There are three ways.

01:27Now,

01:28because the string in English,

01:30the comma exists.

01:32So,

01:33let's say,

01:35message is equal to single quote.

01:39We will put quotation marks.

01:43This is message.

01:46This is message.

01:48M-E-S-S-S-E-G.

01:49Message.

01:50Okay.

01:51Now, I print it.

01:52No surprise.

01:53I print.

01:54No surprise.

01:55Then, message will be displayed.

01:57Make sense?

01:58I run it.

01:59This is message.

02:00However,

02:01however,

02:02if

02:03if

02:04if you know English

02:05in English,

02:06there is a name of grammar.

02:07And in grammar,

02:08there is an apostrophe.

02:09There is a quotation.

02:10Let's say,

02:11this is

02:12M-E-S-S-E-S-S-E-S-E-G.

02:15Yes.

02:16What is this?

02:17What is this?

02:18Now,

02:19I-D-E

02:20J-E-B

02:47string ko represent karne ka wohi double quotes.

02:49Toh agar mein ab double quotes me is ko ڈalta hoon.

02:51Now its happy.

02:53This is motion's message.

02:55This is motion's message.

02:57Right run

02:59You get the point.

03:01Ab

03:03Abnei gawr karna hai.

03:05Abnei double quote ڈal diya.

03:07Toh chaliyye.

03:09Let's say mein kehta hoon quote.

03:11Define karte hai.

03:13Quote.

03:15Or us quote ke anndar

03:17Hem eek

03:19Quote liknay lega hai.

03:21Or quote mein kehta hoon

03:23I remember you said

03:27Colon

03:31Quote.

03:33Never give up.

03:35Make sense?

03:37Haan.

03:39He toh confused hoogya python.

03:41Woh kehta hai.

03:43If you have to be here

03:45Toh tuhaarhi string here

03:46However,

03:47How ever,

03:49Now,

03:50Inglish grammar ke anndar

03:51You have to quote.

03:52If you have to quote,

03:53You have to quote.

03:54Confusion.

03:55Confusion.

03:56This is why

03:57Doh tariqe hoon.

03:58Single quote.

03:59If you have to quote.

04:00If you have to quote.

04:01Now,

04:02it is going to be the very happy person.

04:05Now,

04:06it is going to be the very happy person.

04:07I remember you said never give up.

04:10Okay.

04:11Excellent.

04:12So,

04:13This is two way.

04:14A string ko represent.

04:15However,

04:17If I have a full paragraph,

04:20Multi line paragraph,

04:22This is a multi line paragraph.

04:23This is a multi line paragraph.

04:24This is a multi line paragraph.

04:25I will quote.

04:26Sorry.

04:27This is a line.

04:28This is a line.

04:29But when I have to quote,

04:31If I have a new line line,

04:33Then again,

04:35The structure string ko,

04:36Python lose.

04:37This is a multi-quote.

04:38So,

04:39I don't understand.

04:40It's totally.

04:41Interesting enough.

04:42To be sure.

04:43I don't understand this.

04:44Totally.

04:45Interesting enough.

04:46So,

04:47To be sure.

04:48Multi line paragraph.

04:49Multi line passage.

04:50Multi line string ko represent.

04:51The third method.

04:53That is our triple quotes.

04:54I will say.

04:55It is a triple quotes.

04:56I will say.

04:57This is a variable.

04:58It will be a multi-quote.

04:59And,

05:00I will say.

05:01I will say.

05:02It will be a variable.

05:03It will be a multi-quote.

05:04Multi-quote.

05:05Multi-quote.

05:06multi underscore line

05:08is equal to

05:10now you have to go on

05:111, 2, 3

05:12when I put this 3

05:15then I can basically

05:16I can just insert the line

05:19even in full paragraph

05:20I can do it

05:21but then I can close the line

05:23then I can do it

05:261, 2 and 3

05:28now it's happy

05:29if I put this line

05:32I can do it

05:34now I can do it

05:36now I can do it

05:38now it's happy

05:40makes sense

05:42there are 3 different ways

05:44single code, double code and triple code

05:46triple code

05:48single and double

05:50alternatively use

05:52you can use any

05:54just to make sure

05:56if you start using single code

05:58if you start using single code

06:00just to be consistent
