Lecture 34: Python has Boolean Data Type

Nafees AI Lab

The boolean data type in Python represents truth values, and can only have one of two possible values: True or False. These values are keywords in Python and must be capitalized correctly. Booleans are often the result of logical operations or comparisons.

00:00Welcome back.

00:02So, now we have studied data types in string.

00:07And we have seen how it is ordered sequence.

00:10So, let's talk about boolean.

00:12In boolean, there are only two types exist.

00:15Either true or false.

00:17And if we go back to you,

00:20we will see an example.

00:22If you look true,

00:25this is blue turn.

00:27Python is recognized.

00:31Built-in key words.

00:33True and false.

00:34Imagine,

00:35this usage is used in program flow control,

00:42when you have to decide.

00:44Imagine, you have to come to camera,

00:46and you have to use light.

00:48But first of all,

00:49you want to check the light.

00:50So, I will define a variable.

00:52Has light.

00:53And is equal to true.

00:56Okay.

00:57Now, if you print it,

00:59if you print it,

01:00if you print it,

01:01it will show false.

01:02Of course, it will print true.

01:04Right?

01:05Because,

01:06has light true.

01:07If you print it,

01:09if you print it,

01:10then,

01:11has light false.

01:12And when you print it,

01:14it will show false.

01:15Interesting.

01:16Right?

01:17However,

01:18this means,

01:19is a change of condition,

01:21which means I may say,

01:22is a change of condition.

01:23For example,

01:24has light false.

01:25So,

01:26this means to turn on the switch.

01:28It means that

01:29we can create decision.

01:30So,

01:31decision you can create.

01:32We have to see the boolean and condition,

01:34which means you receive.

01:35Another keyword is true and false.

01:37true and false

01:37to be

01:38and true I'll do

01:38that it's bull

01:39bull

01:40bull

01:41bull

01:42Blue

01:43which is

01:43that bull

01:430

01:440

01:45false

01:45treat

01:46and 0

01:470

01:59physical

02:00and

02:000

02:01true

02:01treat

02:01and

02:02by the way

02:02normal

02:03convention

02:03I'll see

02:041

02:042

02:051

02:052

02:06کوئی number ہے نا zero کے علاوہ ہے

02:07تو اس کو یہ true treat کرے گا

02:09by the way یہ minus بھی ہو سکتا ہے

02:10but it's still not zero

02:12تو zero کے علاوہ کوئی بھی number true treat

02:14کیا جاتا ہے

02:15اسی طرح جب آپ کو string اس کو دیتے ہیں

02:18let's say this is string

02:20اور اس کو run کرتے ہیں

02:21تو bool کا جو value ہے

02:24وہ اس کو as a true consider کرتی ہے

02:25کیونکہ this is a string

02:27کوئی value ہے

02:28جب آپ اس کو کوئی value نہیں دیتے

02:30تو پھر یہ اس کو false treat کرتے ہیں

02:32میں اس کو دوبارہ run کرتا ہوں

02:34and you see it's false

02:36اب یہ دو چیزیں true اور false

02:39ہمارے بہت کام آنے والی ہیں

02:41جب ہم conditional flow control

02:43یا program flow control کی بات کریں گے

02:45congratulations

02:46یہ سب سے چھوٹی data type تھی

02:48اور سب سے آسان تھی

02:49ایسا ہی ہے نا

02:50I hope you guys have enjoyed it a lot
