If a loop exists inside the body of another loop it's called nested loop.

00:07.030 --> 00:15.130
Let's see an example of nested loop.

00:15.300 --> 00:24.160
You see I equal to 1 create a while loop IE is less than equal to

00:28.020 --> 00:31.000
every revolutionized.

00:31.010 --> 00:31.840
Another variable

00:34.900 --> 00:43.170
and then we started another loop seeing J is less than equal to 5.

00:43.280 --> 00:46.200
Here we are printing the values of

00:49.440 --> 00:53.950
i and j.

00:54.100 --> 00:54.580
Saying

01:05.860 --> 01:18.490
then will increase in the value of j by 1 slow this loop will execute 5 times and then we are saying

01:18.550 --> 01:22.660
increase the value of a by 1

01:25.320 --> 01:27.190
or save this program as

01:30.530 --> 01:31.220
nested loop

01:37.000 --> 01:38.580
let's execute the program.

01:41.220 --> 01:52.110
So observe that when the value of I was 1 the inner loop executed 5 times and the value of j changed

01:52.110 --> 02:03.760
from 1 to 5 after that the outer loop started second time and the value of ages 2 to and again the inner

02:03.780 --> 02:07.480
loop executed 5 times.

02:07.540 --> 02:15.760
This is how nested loop works in pattern let's do some changes in the program

02:22.410 --> 02:27.460
look here instead of i.e. less than equal to say less than equal 5.

02:27.520 --> 02:31.210
And here we see I sorry j is less than equal to

02:34.160 --> 02:42.120
here will bring the value of j and let's see what.

02:48.180 --> 02:56.640
So observed the output here the output is 1 One two one two three one two three four one two three four

02:56.640 --> 03:07.570
five So whenever the print statement executes it changes the line.

03:07.610 --> 03:09.890
Why do we don't want that.

03:09.920 --> 03:16.310
What if we want the output to be like one one two one two three one two three four and one two three

03:16.310 --> 03:16.810
four five

03:19.390 --> 03:30.690
So the print function comes with an optional barometer card and and the default value of this parameter

03:30.720 --> 03:35.800
is new line meaning after print changed the line.

03:36.620 --> 03:45.480
So here we are changing the value of end barometer to NUM and after print in one line

03:52.510 --> 03:53.940
go to the next line.

03:57.000 --> 04:07.110
Let's see the output Mark.

04:07.150 --> 04:13.710
This was a little variation with the print statement see you in the next lecture.
