<v Instructor>Hi, welcome back.</v>

2
00:00:01.800 --> 00:00:03.620
Just a small aside actually,

3
00:00:03.620 --> 00:00:06.200
before we move on to anything else.

4
00:00:06.200 --> 00:00:08.390
I wanted to show you a slightly more efficient way

5
00:00:08.390 --> 00:00:10.550
of creating your menus.

6
00:00:10.550 --> 00:00:12.437
Instead of having all these if statements,

7
00:00:12.437 --> 00:00:15.030
you could just put the user choices

8
00:00:16.810 --> 00:00:18.260
into a dictionary,

9
00:00:19.440 --> 00:00:22.720
where B is assigned to print best books,

10
00:00:22.720 --> 00:00:25.190
the function, not the result.

11
00:00:28.010 --> 00:00:30.080
C to print cheapest books.

12
00:00:33.220 --> 00:00:36.760
And N to get next book.

13
00:00:38.580 --> 00:00:42.440
Once you've got this, you can essentially get rid of

14
00:00:42.440 --> 00:00:44.860
all of these statements here.

15
00:00:44.860 --> 00:00:46.880
Instead of user input equal B,

16
00:00:46.880 --> 00:00:51.880
we can say user input in B, C, N.

17
00:00:52.311 --> 00:00:54.040
So this is going to give us true

18
00:00:54.040 --> 00:00:56.510
if the user input is one of these things.

19
00:00:58.050 --> 00:01:03.050
And if it is, we can just do user choices, user input.

20
00:01:03.940 --> 00:01:05.850
This is going to give us the function

21
00:01:05.850 --> 00:01:09.000
that is associated with the input inside this dictionary,

22
00:01:10.570 --> 00:01:11.570
and we can run that.

23
00:01:12.620 --> 00:01:15.320
It is a much more efficient way of doing the same thing.

24
00:01:15.320 --> 00:01:16.830
Essentially, you get to type less code,

25
00:01:16.830 --> 00:01:18.610
it does the same thing.

26
00:01:18.610 --> 00:01:19.830
Okay, that's it for this video.

27
00:01:19.830 --> 00:01:21.470
Just wanted to show you this because you're going

28
00:01:21.470 --> 00:01:23.080
to be writing menus quite often,

29
00:01:23.080 --> 00:01:26.420
might as well know the best way of doing them.

30
00:01:26.420 --> 00:01:27.920
Now see you on the next video.
