1
00:00:00,070 --> 00:00:02,170
All right, so let's go through the solution together.

2
00:00:02,680 --> 00:00:07,680
Now we know that the part that we need repeating is this part where we ask the

3
00:00:08,530 --> 00:00:11,890
user to guess a letter again and again

4
00:00:12,220 --> 00:00:16,090
until they filled out all the blanks in this display.

5
00:00:16,720 --> 00:00:21,720
The first step is to wrap a while loop around this block of code so we can

6
00:00:23,200 --> 00:00:28,200
select the entire block of code and you can either indent it individually or

7
00:00:28,510 --> 00:00:33,510
just select all of it and hit command and the right square bracket.

8
00:00:34,360 --> 00:00:37,600
And that will shift everything by one indentation level

9
00:00:37,870 --> 00:00:41,140
and that effectively puts it inside our while loop.

10
00:00:41,650 --> 00:00:43,960
So now we have to define our while loop.

11
00:00:44,290 --> 00:00:48,100
So while something is true or while something is false,

12
00:00:48,340 --> 00:00:53,170
repeat this code again and again. So what exactly is our condition?

13
00:00:54,130 --> 00:00:59,130
We know that we only want our loop to end once there are no more blanks

14
00:00:59,710 --> 00:01:02,830
contained inside the list called display.

15
00:01:03,550 --> 00:01:08,550
Why don't we create a variable which we'll call end_of_game and set that to

16
00:01:10,750 --> 00:01:11,320
false

17
00:01:11,320 --> 00:01:16,320
to begin with because it's not yet the end of game. And while it's not yet at the

18
00:01:17,290 --> 00:01:22,240
end of game, so while this is false. So you can either say while

19
00:01:22,240 --> 00:01:26,710
end of game is equal to false or alternatively

20
00:01:26,800 --> 00:01:31,800
and I think slightly easier to read is you could say while it's not at the end

21
00:01:32,440 --> 00:01:36,250
of the game, then repeat this continuously. Now,

22
00:01:36,280 --> 00:01:38,290
if we were to run our code right now

23
00:01:38,320 --> 00:01:41,530
it would actually loop on until forever.

24
00:01:41,620 --> 00:01:44,380
It would not stop because nowhere in our code,

25
00:01:44,590 --> 00:01:47,410
do we actually flip the switch and change this true.

26
00:01:48,100 --> 00:01:50,770
So when is it actually the end of the game? Well,

27
00:01:50,770 --> 00:01:53,650
it's when display has no more blanks.

28
00:01:54,640 --> 00:01:59,640
So why don't we check at the very end after we've printed the display to see if

29
00:02:01,630 --> 00:02:06,040
blanks are not in display.

30
00:02:07,180 --> 00:02:12,180
So remember this in key word comes from Python and it basically allows us to

31
00:02:12,760 --> 00:02:17,760
check to see if a particular element exists inside a particular list. So in this

32
00:02:18,730 --> 00:02:23,260
case, we're checking if curly exists in list and there it is.

33
00:02:23,260 --> 00:02:26,980
I can see it as one of the elements. So this is going to be true.

34
00:02:28,270 --> 00:02:30,220
Now, if blank

35
00:02:30,310 --> 00:02:34,150
in list is no longer true, well,

36
00:02:34,150 --> 00:02:38,110
that means that we've gotten rid of all the blanks and we replaced them with

37
00:02:38,110 --> 00:02:39,700
letters that the user has guessed.

38
00:02:40,090 --> 00:02:44,140
So now this is the condition for the user having won.

39
00:02:44,530 --> 00:02:47,710
So we can flip the end of game to true

40
00:02:48,340 --> 00:02:50,380
and this will mean that this is last time

41
00:02:50,500 --> 00:02:55,500
our while loop is going to run and we're going to print "You win."

42
00:02:57,580 --> 00:03:01,870
That's it, that's all we needed do. And if it's helpful,

43
00:03:01,930 --> 00:03:06,130
you can again, take this code, put it into Thonny and run through it

44
00:03:06,220 --> 00:03:10,060
using the debug step-by-step to see what it's doing. Now

45
00:03:10,120 --> 00:03:15,120
the important thing here is to realize that while statements require some sort

46
00:03:15,820 --> 00:03:19,090
of change to happen inside the while loop

47
00:03:19,390 --> 00:03:23,320
that changes the condition that the while loop is dependent upon

48
00:03:23,680 --> 00:03:28,240
and it means the code exits the while loop. So in this case,

49
00:03:28,270 --> 00:03:32,380
it's when there are no longer any more blanks inside the display list.

50
00:03:32,920 --> 00:03:34,330
But in later steps,

51
00:03:34,390 --> 00:03:37,600
we're going to change that so that when the users has run out of lives,

52
00:03:37,870 --> 00:03:41,620
then it's also going to be the end of the game and they will have lost.

53
00:03:42,880 --> 00:03:45,220
So take a moment, review this lesson,

54
00:03:45,370 --> 00:03:47,500
make sure you understand everything that's going on.

55
00:03:47,890 --> 00:03:51,520
Then head over to the next lesson and we'll tackle the next step.
