1
00:00:04,670 --> 00:00:08,290
In this video, we're going to produce the
menu for a juke box

2
00:00:38,120 --> 00:00:46,840
Alright, so let's create a new file.
I'm going to call this one demo.py.

3
00:00:46,840 --> 00:00:49,980
I'm gonna paste the code in.

4
00:00:51,440 --> 00:00:57,540
So I'm going to run this first. Now that 
it's running, I'm gonna come over here,

5
00:00:57,540 --> 00:01:03,440
click on the cog. Then I'm gonna choose 
View Mode, or set View Mode, to Window.

6
00:01:03,440 --> 00:01:05,900
Then what I'm going to do is,
just make this window so it's a little bit

7
00:01:05,900 --> 00:01:09,060
bigger, so you I see more of the
output, but I'm also going to make sure I

8
00:01:09,060 --> 00:01:13,020
leave enough room for the subtitles to
still be displayed at the bottom of the screen.

9
00:01:13,020 --> 00:01:16,080
Alright, so now the program's running, 
we've got a menu showing our albums

10
00:01:16,080 --> 00:01:20,200
from our albums list. We can
enter any of the options from 1 to 4,

11
00:01:20,200 --> 00:01:25,820
to select an album. I'm going to choose
option 3, Nightflight. Next, we see the

12
00:01:25,830 --> 00:01:30,149
songs on the album I chose. Once again,
there's 4 options, as you can see.

13
00:01:30,149 --> 00:01:36,600
I'll select Reaper of the Glory, option 3. If
this was a real juke box, the song would

14
00:01:36,600 --> 00:01:41,320
now be playing. The main menu's appeared
again, showing the album's, once more.

15
00:01:41,320 --> 00:01:46,920
I'll try option 2 is time, Bad Company, and
this time you can see, we've got 8 tracks

16
00:01:46,920 --> 00:01:52,380
to choose from. Seagull's a good one -
option 8 - so I'm going to select that. OK.

17
00:01:52,380 --> 00:01:56,240
So that's what our program's going to
do. It'll present the songs available,

18
00:01:56,240 --> 00:02:01,440
for each album that we select. If you enter
an invalid choice, the program exits.

19
00:02:01,440 --> 00:02:06,280
0 is invalid, and so is any number
greater than the last album or song.

20
00:02:06,280 --> 00:02:10,620
Make sure you only enter whole numbers, though.
Entering text will crash the program.

21
00:02:10,620 --> 00:02:14,700
We look at how to handle that, later in the
course. I'll finish here by entering 7

22
00:02:14,700 --> 00:02:21,200
to quit the program, and in the next video,
we'll start writing the code for this program.

23
00:02:21,200 --> 00:02:24,320
See you in the next video.
