00:00:00,290 --> 00:00:01,940
- [Instructor] In this
Self Check exercise,

2
00:00:01,940 --> 00:00:04,490
I'd like you to go ahead and
create a list of integers

3
00:00:04,490 --> 00:00:06,480
containing these five values,

4
00:00:06,480 --> 00:00:09,710
then use the list method index
that we just demonstrated

5
00:00:09,710 --> 00:00:13,810
to you to search for both
the values 43 and 44.

6
00:00:13,810 --> 00:00:18,040
And of course, 43 will be in
the list, and 44 will not.

7
00:00:18,040 --> 00:00:19,940
Now when you do search for 44,

8
00:00:19,940 --> 00:00:23,180
make sure that no value error occurs.

9
00:00:23,180 --> 00:00:24,940
So go ahead and pause the video

10
00:00:24,940 --> 00:00:27,150
and give that a shot
and then come back here

11
00:00:27,150 --> 00:00:28,453
to see the results.

12
00:00:32,190 --> 00:00:34,250
Okay, let's check out the results.

13
00:00:34,250 --> 00:00:37,070
So first, we need to create that list.

14
00:00:37,070 --> 00:00:41,360
Now, we happen to know in this
case that 43 is in the list.

15
00:00:41,360 --> 00:00:44,230
So for this one, we simply
are going to evaluate

16
00:00:44,230 --> 00:00:47,890
the expression numbers.index
with 43 as an argument,

17
00:00:47,890 --> 00:00:50,300
and we know we don't need
to worry about an exception

18
00:00:50,300 --> 00:00:54,050
occurring just because we can
see what we put into the list.

19
00:00:54,050 --> 00:00:56,010
Of course, you may want to program

20
00:00:56,010 --> 00:00:59,520
that differently in a
more robust application.

21
00:00:59,520 --> 00:01:01,310
But for the second piece here,

22
00:01:01,310 --> 00:01:03,570
where we wanna search for the value 44.

23
00:01:03,570 --> 00:01:06,540
Again, we can validate that the value

24
00:01:06,540 --> 00:01:11,540
is in the list before we
perform the indexing operation.

25
00:01:11,940 --> 00:01:15,950
So if 44 is found in
the list called numbers,

26
00:01:15,950 --> 00:01:18,440
then and only then will we go ahead

27
00:01:18,440 --> 00:01:21,380
and actually search for the value

28
00:01:21,380 --> 00:01:23,020
and find out its index,

29
00:01:23,020 --> 00:01:26,210
otherwise, we're going to
print that 44 is not found.

30
00:01:26,210 --> 00:01:29,983
So let's execute that and
indeed 44 is not found.
