Lecture 56: A Range Function in Python

Nafees AI Lab

The range() function in Python generates a sequence of numbers. It is commonly used in loops to iterate a specific number of times. The function can take one, two, or three arguments: range(stop): Generates numbers from 0 up to (but not including) stop, incrementing by 1. range(start, stop): Generates numbers from start up to (but not including) stop, incrementing by 1.

00:00Now we will talk about range function, but I will explain the range function, and then I will show you the utilization of it.

00:09Now, in the last lecture, I had a point that I had said that I had a list of 100 of the list.

00:17So, 100 of the list will generate 100 of the list.

00:22So, this is 10, 11, 12, 13, so I have a list of 100 to be efficient way to generate.

00:32So, this is a built-in function.

00:34Range is a range.

00:36Range is a range.

00:38Range is a range function, and I remove this function.

00:42And then I will remove this function.

00:45So, we will do this function.

00:48Range is a function.

00:50Your function is a function function too.

00:53wide!

00:55Can you choose some effect again?

00:56Notice that there needs to be constant.

00:57The 정도 function of speed function goes...

00:59If you want to� govern maintenance function, do you have 6 of the page function or do you need to choose?

01:05If I understand the benefits function is a change function, I will стres the functionだ.

01:07So, over the slide, I will send you 2 of these functions.

01:11So, change the values function, 4 of theuli functions functions.

01:13The number of these functions function is 5 elements.

01:15If I run as matches function, if I run without addinguche functions then you cannot exclude.

01:17If you have step size, then automatically step size is 1.

01:21If you have step size 2, then it will be 0, 2, 4, 6.

01:25If you have step size 3, then it will be 0, 3, 6 and 9 and so on.

01:30Okay, so this is step size.

01:31So, first of all, simple range to generate.

01:34Now, if you have to print this range,

01:37you will see that you will see that we will get a range iterator,

01:41but it will not get a range.

01:43And range is 0 to 10.

01:46So, you can ask me,

01:48Sir, you promised me that you will get a list from 1 to 10.

01:51But the list will not come.

01:52However, interesting enough,

01:54that we will get an iterator.

01:56We can use this straight away.

01:58We can convert this to the list.

02:02Using the list function.

02:04Now, I will execute this list.

02:08And it gives me an error.

02:10The reason is that I have parenthesis here.

02:14And you see list.

02:160 to 9.

02:17However,

02:18we can use this for loop.

02:20We can use this for loop.

02:21For x in range.

02:23And range is 0 to 10.

02:27Print x.

02:29Execute.

02:30And you will see.

02:320 to 9.

02:33So, you will find the list.

02:34And you will find the list.

02:35And you will find the proper operation.

02:36Okay?

02:37Now, you will find it.

02:38Range.

02:39Basically.

02:40If I simply write this as a range.

02:4410.

02:45Then I will write exactly this.

02:48Range.

02:490 to 10.

02:51Okay?

02:52Okay?

02:53So, if you have a default start value.

02:55If you have a default start value.

02:56Then the defaults count.

02:57So, in this case.

02:58For example.

02:59I will say range 10.

03:00Generate.

03:01Okay.

03:02Range.

03:03Range.

03:04If you want to generate even number.

03:07Or list.

03:08Or odd number.

03:09You can easily do that.

03:11With no problem.

03:12I will say 0 to 10.

03:14But on every two steps.

03:17Step.

03:18So, this is which.

03:19Sorry.

03:20I will convert it in the list.

03:21And then I will print it.

03:24Just like that.

03:25P-R-I-N-T.

03:26Execute.

03:27So, this will give us a list.

03:30Which numbers?

03:310, 2, 4, 6.

03:32Even numbers.

03:33Just like that.

03:36What if.

03:37If I need odd number.

03:38So, I will start with step size 2.

03:41Step size 2.

03:422, 3.

03:43And so on.

03:442, 3.

03:45And so on.

03:46The list.

03:47Now interesting enough.

03:48I will just add 0 to odd.

03:51And you will have an odd number list.

03:52Until 100.

03:53Isn't it cool?

03:54It's very cool.

03:55And if I have 0.

03:56So, if I have a list.

03:57You have to have a list.

03:58You have to have a list.

03:59This is very cool.

04:00And very powerful.

04:01This is very cool.

04:02And very powerful.

04:03Now we will do this.

04:05We will do this.

04:06On the previous code.

04:07And this range.

04:08And this range.

04:09I will use.

04:10Okay.

04:11We will do this.

04:12We will do this.

04:13We will do this.

04:14We will do this.

04:15And then.

04:16And then.

04:17Range 10.

04:18That's it.

04:19Now we will do this.

04:20We will do this.

04:21And then.

04:22And then.

04:23Range 10.

04:24That's it.

04:25Now we will do this.

04:26We will do this.

04:27We will do this.

04:28Now we will do this.

04:29We will do this.

04:30We will do this.

04:31Now we will do this.

04:32Now we will do this.

04:33And we will do this.

04:34and you see the same result, this is cool, right?

04:38However, a small thing,

04:40basically, if you are 10,

04:42you will print 10 elements, starting from 0,

04:45okay, starting from 0,

04:4810 elements to print,

04:49this total is 9,

04:50so this is why this is 9,

04:51then you have to include,

04:52make sure,

04:53that you have to go up to a number.

04:55This is the number of elements,

04:57okay,

04:58now you will see,

04:59that you will have full range,

05:02now you will see,

05:04100 to generate,

05:07how clean code is,

05:09and you have got everything you want,

05:11as you see,

05:12right?

05:13It is very cool,

05:14okay,

05:15so this is all table,

05:16within snap of a finger,

05:17generate,

05:18now range is a hidden function,

05:21which basically,

05:22I don't know how many people know,

05:24I will tell you.

05:25If you give range,

05:260 is start point,

05:28and 10 is end point,

05:29and not anything else,

05:31when I write,

05:34basically list,

05:35I will tell you,

05:37basically list generate,

05:38this list generate,

05:39you are going to tell me,

05:40it will be,

05:41okay,

05:42alright,

05:43I will tell you,

05:44this list can name,

05:45I will tell you,

05:46comment out,

05:47comment out,

05:49execute,

05:50and then,

05:51to 10 is end point,

05:52I will tell you,

05:53right,

05:54what if,

05:55I will say this list,

05:56reverse
