Lecture 50: Python with Boolean values

Nafees AI Lab

To assign a boolean value in Python, use the keywords True or False. These are the only two boolean values in Python and are case-sensitive. You can assign them directly to a variable or as the result of a boolean expression.

00:00In the first lecture, we had to play with Billy and Billy.

00:03We had to play with the end condition,

00:06so that Billy and the dog should be together,

00:11so that the dog should be.

00:12Right?

00:13Good.

00:15Now, we have to note that

00:18I use the values of direct boolean values.

00:22What if I write,

00:25and here I write,

00:30what do you think?

00:35Basically, I do not like this,

00:39that cat,

00:42and dog,

00:44because this variable is the value of the value.

00:48So what do you think?

00:51This is the value of the value.

00:56If you give it to the condition,

00:58it will be a boolean.

01:03So if you give it to true value,

01:06it will be a false return.

01:08If I execute it,

01:10what do you think?

01:11Let's see.

01:13Run.

01:14And mouse run away.

01:16Interesting enough.

01:18This value has been true return,

01:20and this value has been true return.

01:22How is it possible?

01:24How is it possible?

01:25How is it possible?

01:26That meow true is.

01:27Boolean.

01:28And wolf true is.

01:30How is it possible?

01:31One rule of thumb is,

01:34that you call a simple bool function,

01:37and then check the value for what it returns.

01:40Let's say,

01:41I give the bool to this,

01:42and the bool to this,

01:43and the bool to this,

01:44and the wolf to this.

01:45See we will see,

01:46what bool is.

01:47Why?

01:48Because condition is,

01:50at the end,

01:52bool function of the bool form,

01:53the value is called at the end.

01:55The value is called.

01:57The value is above.

01:58The bool function of the bool function,

02:00the bool function of the bool function.

02:02The return as well.

02:03Before the bool function of the bool function,

02:06the bool function is called at the end.

02:09So that doesn't belong.

02:10Now,

02:11I will see.

02:12I mean, I will execute that both are true.

02:14Isn't it interesting?

02:16Very interesting.

02:18If meow and woof true are,

02:21then all which things are true?

02:23Interesting, right?

02:25If meow and woof are boolean in true return,

02:28then it could be true exactly.

02:31Then, false, which will be true?

02:33Very good question.

02:35False, which is very limited.

02:37True, which is unlimited.

02:39Basically, I am going to add a list.

02:41These values, none, false, zero,

02:45zero point zero, zero j, decimal of zero,

02:48fraction zero one,

02:50empty list, dictionary, empty tuple,

02:52empty string.

02:54Okay?

02:55Empty byte, empty set.

02:58These values are false.

03:00I am not sure.

03:02Let's do it.

03:04Empty string is false.

03:06I am not sure.

03:08meow and woof,

03:30I will do this.

03:31I will do this.

03:32Cat replace.

03:33Okay.

03:34And here we go.

03:35Cat.

03:36Cat.

03:37Cat.

03:38Now we execute.

03:39And Kaboom Shaka Allah.

03:42Mouse.

03:43Why?

03:44Empty string.

03:45False return.

03:46Isn't it cool?

03:47It's very cool.

03:49If you give empty list.

03:53And in the other place, you give empty dictionary.

03:58Right?

03:59It's exactly your suit.

04:01You are saying the same thing.

04:03Mouse eat the cheese.

04:05Right?

04:06So basically, this is how I know.

04:09If you think about it.

04:10I know about Google.

04:13Isn't it interesting?

04:15Very interesting.

04:16You don't have to memorize anything.

04:20Don't memorize anything.

04:22If you are programming.

04:24Please stop right now.

04:27Right now.

04:28Right now.

04:29Stop.

04:30Don't memorize anything.

04:31Everything is available.
