WEBVTT 0 00:00.080 --> 00:02.780 Hey, you've reached the final project. 1 00:02.780 --> 00:09.530 And as you've seen at the beginning of today's lessons, I showed you what we're going to be making, 2 00:09.530 --> 00:12.590 which is a sort of, Choose Your Own Adventure Game. 3 00:12.590 --> 00:14.000 I don't know if you've ever read those, 4 00:14.000 --> 00:20.120 "Choose Your Own Adventure Books," where you flip to a different page if you make a particular choice, 5 00:20.120 --> 00:24.200 and then the story kind of evolves as you make your choices. 6 00:24.200 --> 00:30.050 Now we're going to make a very simple version of that using what we've learned about conditionals, 7 00:30.050 --> 00:34.550 if, else, elif statements, as well as everything we've done previously. 8 00:34.550 --> 00:38.390 So you've already seen what the final outcome should look like, 9 00:38.390 --> 00:44.600 and if you want to review it again, just head over to the link in the URL box or click in the Course 10 00:44.600 --> 00:47.300 Resources and it'll direct link you here. 11 00:47.510 --> 00:51.320 And here you'll see essentially the game in action. 12 00:51.320 --> 00:55.120 So it start off asking you, "You're at a crossroad. 13 00:55.120 --> 00:56.740 Do you want to go left or right?" 14 00:56.740 --> 00:59.320 And then you have to type your choice. 15 00:59.920 --> 01:04.300 If you selected left, then it's going to take you to a lake, 16 01:04.420 --> 01:08.500 and it asks you whether if you want to wait for a boat or swim across. 17 01:08.500 --> 01:11.500 So let's go ahead and wait for a boat. 18 01:11.500 --> 01:18.280 And then the final step is it asks you, which door would you like to go through red, yellow or blue? 19 01:18.310 --> 01:24.880 Now, depending on your choice, you'll either end up with Game Over or you'll end up with winning 20 01:24.880 --> 01:25.480 the game. 21 01:25.480 --> 01:29.800 So the basic setup for this game looks something like this. 22 01:29.800 --> 01:36.760 And I've included a link to the flowchart in the starting project right here. 23 01:37.300 --> 01:41.740 And of course, you'll find all the links in the Course Resources as always. 24 01:41.740 --> 01:47.740 Now, the first question you're going to ask the user is to make a choice between left and right. 25 01:47.770 --> 01:50.590 Now you can use my wording if you want, 26 01:50.590 --> 01:51.520 "You're at a crossroad. 27 01:51.520 --> 01:52.360 Where do you want to go? 28 01:52.360 --> 01:53.920 Type 'left' or type 'right'." 29 01:53.920 --> 01:59.140 But I think the fun part of this challenge is really creating your own story, right? 30 01:59.140 --> 02:02.560 But somehow get them to choose between left and right. 31 02:02.560 --> 02:06.520 If they choose right or any other condition for that matter, 32 02:06.550 --> 02:11.170 tell them that they've lost, 'Game Over' for some sort of reason. 33 02:11.410 --> 02:15.850 In my case, if they had chosen right, the reason is because they fell into a hole, 34 02:15.850 --> 02:16.660 Game Over. 35 02:16.660 --> 02:22.870 But I think you're far more imaginative than I am, so go ahead and use all of those skills and make 36 02:22.870 --> 02:23.920 your game really fun. 37 02:23.950 --> 02:28.750 Now, if they've chosen left, on the other hand, then we're going to take them to another question 38 02:28.750 --> 02:33.330 that asks them whether they want to swim or whether if they want to wait for a boat. 39 02:33.480 --> 02:37.950 And if they swam, then it's going to be some form of Game Over. 40 02:37.950 --> 02:43.050 There's crocodiles, there's...whatever it may be, but they can't continue. 41 02:43.050 --> 02:47.940 But if they chose wait, then we take them to the third and final question, which asks them to choose 42 02:47.940 --> 02:53.850 between three doors and if they choose any door other than the yellow door, then they would lose, 43 02:53.850 --> 02:56.800 but if they chose the yellow door, then they somehow win. 44 02:56.830 --> 03:01.240 Now notice how each of these just says, Game Over, Game Over, left or right, 45 03:01.240 --> 03:06.760 but you know, the idea is really to use your creativity and make this game really your own. 46 03:06.970 --> 03:12.970 Now, one thing to remember, though, is that when the user types in an answer, let's say left or right, 47 03:12.970 --> 03:18.250 they might type it like this with an uppercase R, or they might type it like this, 48 03:18.250 --> 03:19.440 all lowercase. 49 03:19.470 --> 03:20.010 Have a 50 03:20.010 --> 03:24.720 think about how you might make sure that no matter which version they typed, you're still going to 51 03:24.720 --> 03:28.380 be able to catch their command essentially. 52 03:28.380 --> 03:34.200 So have a think about what you've learned in the previous lessons and take a look at this flowchart, 53 03:34.200 --> 03:40.080 then head over to the starting project and you can get started writing your code. 54 03:40.080 --> 03:45.920 Now ASCII art is really cool because it basically just uses a bunch of characters that you know and love, 55 03:45.920 --> 03:53.990 like the comma and the equal sign and all of these things that together make up a picture. And 56 03:53.990 --> 04:01.640 you can find your own ASCII art if you just go to, ascii.co.uk/art, and you'll see a whole bunch of different 57 04:01.640 --> 04:02.510 topics. 58 04:02.600 --> 04:07.220 And they've grouped a lot of things together into individual pages. 59 04:07.220 --> 04:13.790 So if you wanted a Rhino ASCII art, then you can find a whole bunch of rhinos that people have drawn. 60 04:13.940 --> 04:18.740 But the easiest way is, of course, using cmd + F if you're on a Mac, or Ctrl + F if you're on 61 04:18.740 --> 04:22.430 a Windows machine, and then just search for the thing that you want. 62 04:22.430 --> 04:28.820 So, for example, I went and searched for treasure, and down here I found this brilliant Treasure 63 04:28.820 --> 04:35.030 Box in ASCII art, which is what I'm using to print inside this print statement. 64 04:35.030 --> 04:41.600 Now notice how there's three single quotes that are at the start, and there's three single quotes at 65 04:41.600 --> 04:42.350 the end. 66 04:42.350 --> 04:49.250 Basically, what the single quotes allow you to do is to create multiple lines of a string essentially. 67 04:49.250 --> 04:56.770 So notice how if I go ahead and delete all of these single quotes and I only had a set of double 68 04:56.770 --> 05:01.060 quotes then it actually doesn't quite work. 69 05:02.200 --> 05:09.220 It gets quite confused because it thinks that this is where the line ends, but in fact, I wanted 70 05:09.220 --> 05:11.140 it to print all of this out. 71 05:11.140 --> 05:17.950 So to do that, instead of using a double quote, I use three single quotes, and at the very bottom, 72 05:17.950 --> 05:24.010 I tell it well, this is the end of my multi-block string by using three single quotes as well. 73 05:24.010 --> 05:28.090 So have a go at running that, and you should be able to see that in your console, 74 05:28.090 --> 05:34.090 you get this little Treasure Island ASCII art being printed along with the two sentences that begin 75 05:34.090 --> 05:34.810 the game. 76 05:34.900 --> 05:37.420 So have a look at the flowchart, 77 05:37.510 --> 05:44.380 have a play around with the ASCII art, and also have a look at the final version of the app so 78 05:44.380 --> 05:49.540 that you can go ahead and create your own version to complete this challenge. 79 05:49.570 --> 05:51.490 Pause the video now and give that a go. 80 05:55.630 --> 05:56.080 All right. 81 05:56.080 --> 06:02.800 So let's see if we can replicate the functionality or the logic that's shown in this diagram into our 82 06:02.800 --> 06:03.970 Treasure Island game. 83 06:03.970 --> 06:09.660 So the first thing it has to do is we have to ask the user whether, if they want to turn left or right. 84 06:09.840 --> 06:16.050 And after we ask the user this question, we're going to want to capture their input. 85 06:16.050 --> 06:16.410 Right? 86 06:16.410 --> 06:21.840 So let's go ahead and create an input() function and ask our question. 87 06:25.320 --> 06:32.580 Now notice how when I use my double quotes around my string, the double quotes that are inside the 88 06:32.580 --> 06:39.030 double quotes are interpreted as code, because it actually thinks that this is the end of the first 89 06:39.030 --> 06:39.750 string. 90 06:39.840 --> 06:43.050 This is the second string, and this is the final string. 91 06:43.050 --> 06:45.240 This is how the computer is going to see it. 92 06:45.420 --> 06:48.090 Now there's a cool thing that we can do in Python. 93 06:48.090 --> 06:54.900 When we have a string like this, we can enclose a string inside a set of double quotes. 94 06:54.900 --> 06:59.760 And let's say we have a string in here, "Say the words... 95 07:01.980 --> 07:05.670 She said: "hello." " 96 07:07.020 --> 07:15.000 Now, if we want these double quotes to occur and to be viewed as a part of the text, one trick that 97 07:15.000 --> 07:21.510 we can do is instead of using double quotes to enclose our string, we can actually use single quotes 98 07:21.510 --> 07:22.910 around it, instead. 99 07:22.910 --> 07:29.270 And because now we have double quotes inside the single quotes, it will be interpreted as text. 100 07:29.270 --> 07:32.690 And you can see everything inside here is all green. 101 07:32.810 --> 07:40.790 Now, if we try to apply this trick to our input on this line here, there's one slight problem. 102 07:40.790 --> 07:41.690 So let me show you. 103 07:41.690 --> 07:47.280 I'm going to get rid of the final double quote of our string and the first double quote of our string. 104 07:47.280 --> 07:53.010 I'm going to highlight the entire string that I would like to be a part of, the input prompt text, 105 07:53.010 --> 07:58.140 and I'm going to type the single quote button to wrap everything inside. 106 07:58.170 --> 08:06.510 Now we've solved the problem with the double quotes, but we also have a single quote in our sentence. 107 08:06.510 --> 08:12.470 So now what the computer thinks you're trying to do is here's a string, starting single quote, ending 108 08:12.470 --> 08:13.370 single quote. 109 08:13.370 --> 08:19.040 I've written a bunch of other code, and then I've got some other strings left and right. 110 08:19.040 --> 08:22.730 And at the end I've somehow forgotten to close that quote. 111 08:23.360 --> 08:25.310 So how can we fix this? 112 08:25.310 --> 08:34.280 Well, a really, really simple thing is to simply use the backslash button (\), which is used as an escape 113 08:34.280 --> 08:36.530 symbol in programming. 114 08:36.530 --> 08:40.100 So what this says is yes, this is a backslash, 115 08:40.100 --> 08:47.330 but if the backslash occurs in front of any other useful symbol, then it will mean that we're trying 116 08:47.330 --> 08:49.220 to escape this symbol, 117 08:49.220 --> 08:51.620 so don't interpret it as code, 118 08:51.620 --> 08:57.950 and instead, if we run our code, you'll see the input printout in its entirety. 119 08:57.950 --> 09:01.390 'You\'re at a crossroad...'with the apostrophe. 120 09:01.390 --> 09:02.800 'Where do you want to go? 121 09:02.800 --> 09:03.730 Type "left" or "right".' 122 09:03.730 --> 09:07.180 And it's exactly what we wanted to happen. 123 09:07.180 --> 09:10.060 Now, of course, there's other ways that you could have gone around this. 124 09:10.060 --> 09:16.180 You could have just simply said, "You are at..."at a crossroad rather than using the apostrophe. 125 09:16.180 --> 09:19.990 But more often than not, you'll need to use a symbol that you'll need to escape, 126 09:19.990 --> 09:21.610 and you can do that with the backslash. 127 09:21.610 --> 09:23.140 So that's just a quick tip. 128 09:23.320 --> 09:28.240 Now at this point, the user is going to type a message, "left" or "right." 129 09:28.240 --> 09:31.270 So let's go ahead and save that to a variable. 130 09:31.270 --> 09:34.180 Let's call it choice1, equals their input. 131 09:34.180 --> 09:39.310 Now remember how I said they could be typing the answer as Right or as right, 132 09:39.310 --> 09:46.240 so how can we make sure that when we're doing our checks using the if statement we ignore the casing? 133 09:46.360 --> 09:53.260 Well, one way of doing this is we can simply use the lower() function to change their input, no matter 134 09:53.260 --> 10:00.790 how they wrote it: Right, right, or RIGHT, it should all be converted into lower case, to this version. 135 10:00.790 --> 10:06.460 That way we have one thing that we can consistently check for in our if statement, which is coming 136 10:06.460 --> 10:07.060 up next. 137 10:07.060 --> 10:15.180 So we can say if choice1 ==, remember the double equals is checking whether if left-hand 138 10:15.180 --> 10:21.510 side and right-hand side is equal, and the single equal sign is assigning the right-hand side to this 139 10:21.510 --> 10:23.040 particular variable name. 140 10:23.370 --> 10:29.970 Now if choice1 equals the string "right", then it's pretty much game over for our player. 141 10:29.970 --> 10:37.200 So let's go ahead and add our colon and print something like Game Over. 142 10:37.470 --> 10:41.550 Of course, we can elaborate this a little bit more as to why was it game over? 143 10:41.580 --> 10:45.510 Well, because you fell into a hole. 144 10:45.630 --> 10:48.810 This is like the E.T. game from the 80s. 145 10:49.320 --> 10:50.730 Lots of holes. 146 10:51.090 --> 10:53.190 so, "You fell into a hole. 147 10:53.220 --> 10:54.240 Game Over." 148 10:54.810 --> 10:59.100 But what if they had chosen left instead? 149 10:59.130 --> 11:01.830 Well, that takes them on to the next question. 150 11:01.830 --> 11:05.970 So that's the option that will allow them to continue along the game. 151 11:06.870 --> 11:12.900 Now in this case, we could use an else statement and say, well, if they didn't choose right, then 152 11:12.900 --> 11:14.730 they probably chose left, right? 153 11:14.730 --> 11:19.260 But they could have also chosen like an option that was completely not listed. 154 11:19.260 --> 11:24.830 They could have just written something like this, and it would still trigger the else statement. 155 11:24.830 --> 11:29.690 So what we should actually do is to switch it around. 156 11:29.690 --> 11:36.680 So namely, we should say if choice1 is equal to left, 157 11:36.680 --> 11:47.480 well, in that case then they continue in the game, but otherwise, namely, if they chose right or anything 158 11:47.480 --> 11:50.930 else for that matter, then it's pretty much Game Over. 159 11:50.930 --> 11:57.680 So this format makes a lot more sense if you want to continue along the left side of the branch, this 160 11:57.680 --> 11:58.130 way. 161 11:58.430 --> 12:04.580 Now, another thing that you might have realized, because we learned about combining different conditions, 162 12:04.580 --> 12:12.620 is instead of using the .lower() to change the input to lowercase, you could have also said if choice 163 12:12.620 --> 12:20.870 is equal to left, or if choice1 is equal to left spelled like this, that will both work. 164 12:20.990 --> 12:28.010 But I think in terms of succinctness and less code writing, I think this makes a lot more sense 165 12:28.010 --> 12:28.700 to me. 166 12:28.700 --> 12:31.070 So I'm going to continue with this version. 167 12:31.070 --> 12:34.670 But if you did it the other way, that's perfectly valid as well. 168 12:35.420 --> 12:40.270 Now, if their choice1 was left, then they get taken to the next question. 169 12:40.270 --> 12:42.190 "Do you want to swim or do you want to wait?" 170 12:42.910 --> 12:48.370 So let's go ahead and continue the game and create another input. 171 12:48.790 --> 12:55.300 In this input, we're going to ask them a question and say, "You've come to a lake, 172 12:55.330 --> 12:59.800 there is an island in the middle of the lake. 173 12:59.830 --> 13:04.510 Type 'wait' to wait for a boat. 174 13:04.630 --> 13:09.100 Type 'swim' to swim across." 175 13:09.670 --> 13:10.150 Cool. 176 13:10.150 --> 13:13.600 So we've actually got the same problem as we had before. 177 13:13.600 --> 13:21.730 Namely, that this is being interpreted as code rather than as a continuous single string. 178 13:21.850 --> 13:24.580 So do you remember how we fixed this previously? 179 13:24.580 --> 13:30.250 And if you got stuck on this, I recommend having a go at this yourself before I show you the answer. 180 13:31.600 --> 13:32.080 All right. 181 13:32.080 --> 13:38.560 So previously, we said we were going to switch it to single quotes instead so that these double quotes 182 13:38.560 --> 13:41.830 become interpreted as just normal strings. 183 13:41.830 --> 13:43.690 But of course we've got this, 184 13:43.690 --> 13:48.340 "You've", we could, of course, change it to, you have instead of "you've", 185 13:48.340 --> 13:54.670 but if we want to escape the string, we just add a backslash, which is exactly what we did previously. 186 13:55.270 --> 14:01.300 Now, one thing you might notice here is I'm getting a warning here saying PEP 8... 187 14:01.300 --> 14:03.250 So this is a style guidance. 188 14:03.250 --> 14:05.770 This line is too long. 189 14:05.770 --> 14:11.920 And you might have also felt a little bit annoyed having to scroll left and right constantly to be able 190 14:11.920 --> 14:13.900 to see the end of the line. 191 14:13.920 --> 14:16.470 So what can we do in this case? 192 14:16.470 --> 14:24.360 Well, we can actually very easily pick any point in our entirely long string and just hit Enter, and 193 14:24.360 --> 14:30.030 it will automatically do the right thing and make it go on to the next line. 194 14:30.030 --> 14:36.180 Now, this doesn't actually change how it gets printed out, because if I go ahead and stop this and 195 14:36.180 --> 14:41.520 run this code again, you can see it's still typing everything on the same line. 196 14:41.520 --> 14:42.570 "You're at a crossroad. 197 14:42.570 --> 14:43.470 Where do you want to go? 198 14:43.470 --> 14:44.820 Type left or right?" 199 14:44.820 --> 14:47.040 It doesn't actually affect it at all. 200 14:47.040 --> 14:51.120 The only thing it does is it helps our code to be more readable. 201 14:51.120 --> 14:53.460 So we can go ahead and fix this one as well. 202 14:53.460 --> 14:55.890 So wherever you choose, just hit Enter. 203 14:55.890 --> 14:58.710 I did it at the end of a sentence because that makes more sense, 204 14:58.710 --> 14:59.670 but you don't have to. 205 14:59.700 --> 15:03.060 You can actually even put it in the middle of a character if you really wanted to. 206 15:16.800 --> 15:25.230 Now here we're going to see a new warning, and it's basically unhappy with how our indentation looks 207 15:25.230 --> 15:29.360 for this separated second part of the string. 208 15:29.360 --> 15:35.210 So when you hover over some of these PEP 8 warnings, you can actually just click on this button 209 15:35.210 --> 15:37.670 for them to do whatever they think is best. 210 15:37.670 --> 15:43.280 You know, it's like, "All right, you do it, you know, leave me alone and just fix it for me." 211 15:43.280 --> 15:44.990 So they fixed it for us. 212 15:44.990 --> 15:52.430 And as usual with AI and machines it now looks like I have to scroll horizontally again. 213 15:52.430 --> 15:58.760 So let me just fix this so that I put each sentence on a new line so I can see everything in one go 214 15:58.760 --> 16:00.200 without having to scroll around. 215 16:00.200 --> 16:02.990 It's quite good for my sanity. 216 16:02.990 --> 16:07.310 Now, one thing you have to be really careful about is this indentation. 217 16:07.310 --> 16:10.550 Now, this indentation here doesn't really matter at all. 218 16:10.550 --> 16:12.020 It's just all for styling. 219 16:12.020 --> 16:18.620 And the computer was unhappy with having it unaligned with the start of the string. 220 16:18.620 --> 16:21.620 So that's why they asked us to fix it. 221 16:21.620 --> 16:28.850 But the thing that really matters is your code's indentation, because this choice2, getting the input 222 16:28.850 --> 16:36.320 from the user for the second question must be indented inside this if statement, because otherwise 223 16:36.320 --> 16:39.290 it's going to give you an IndentationError. 224 16:39.970 --> 16:47.620 And this means that only when the choice for the first question was left do we actually prompt them 225 16:47.620 --> 16:50.560 for an input and let them continue the story. 226 16:50.560 --> 16:53.530 And then we get to check our choice2. 227 16:53.560 --> 17:02.020 So if choice2 is equal to "wait" then it means that the game will continue, 228 17:03.940 --> 17:05.560 but else, 229 17:05.560 --> 17:11.650 so if they typed "swim" or anything else for that matter, then the game is going to end. 230 17:11.650 --> 17:15.310 So we're going to print and tell them that something terrible happened, 231 17:15.310 --> 17:20.410 "You got attacked by an angry trout. 232 17:22.180 --> 17:23.230 Game Over." 233 17:23.920 --> 17:26.530 Now we can continue along this path. 234 17:26.530 --> 17:28.480 So we're down to here now. 235 17:28.480 --> 17:33.610 And the final question we're going to ask the user is which door do they want to choose. 236 17:33.970 --> 17:41.200 So here I'm going to use an input to send them the message that, "You arrive at the island unharmed. 237 17:41.200 --> 17:44.170 There is a house with 3 doors. One red, one yellow, one blue. 238 17:44.200 --> 17:46.360 Which color do you choose?" 239 17:46.390 --> 17:55.080 Now I'm going to save their choice inside a variable called choice3, lowercase, the answer that 240 17:55.080 --> 17:56.220 they provided, 241 17:56.220 --> 18:01.560 and finally, I'm going to use if, elif, and else to check which one they chose. 242 18:01.560 --> 18:12.960 So if choice3 is equal to "red", elif choice3 is equal to "yellow", 243 18:15.930 --> 18:20.220 elif choice3 is equal to "blue". 244 18:21.000 --> 18:23.220 And then I've got an else. 245 18:23.310 --> 18:28.170 So here are four possible things that could happen if they chose red, 246 18:28.200 --> 18:34.620 then I'm going to tell them that it's game over, but it's going to be some sort of creative version 247 18:34.620 --> 18:35.460 of Game Over. 248 18:35.460 --> 18:39.360 So maybe something like, "It's a room full of fire. 249 18:39.360 --> 18:40.260 Game over." 250 18:40.500 --> 18:43.930 If they chose yellow, on the other hand, 251 18:44.170 --> 18:47.110 well, that's going to be the room where the treasure exists. 252 18:47.110 --> 18:48.610 So I'm going to print 253 18:48.610 --> 18:48.820 , 254 18:48.820 --> 18:49.750 "You found the treasure. 255 18:49.750 --> 18:50.530 You win!" 256 18:50.530 --> 18:55.030 If they chose blue, they also end up with Game Over. 257 18:55.030 --> 18:58.390 And I have to give them a different reason. 258 18:58.780 --> 19:05.670 Now, if you had decided that if they chose anything but yellow, the way that they're going to Game 259 19:05.670 --> 19:07.350 Over is the same. 260 19:07.350 --> 19:10.800 Say, if you know, if you chose red, "It's a room full of fire. 261 19:10.800 --> 19:11.340 Game Over." 262 19:11.340 --> 19:13.410 If you chose blue, "It's a room full of fire. 263 19:13.410 --> 19:14.250 Game Over." 264 19:14.250 --> 19:15.300 Anything else, 265 19:15.300 --> 19:16.980 it's also going to be fire, 266 19:16.980 --> 19:17.850 Game Over. 267 19:17.850 --> 19:20.490 Well, then you could just use if and else. 268 19:20.490 --> 19:26.610 But if you wanted each choice or each door to have a different outcome for the user, say the red door 269 19:26.610 --> 19:28.890 has fire, the blue door has beasts, 270 19:28.890 --> 19:35.780 and if they chose the wrong door, then they're going to get something like, "You chose a door that doesn't 271 19:35.780 --> 19:36.290 exist. 272 19:36.320 --> 19:37.280 Game Over." 273 19:37.520 --> 19:44.810 So can you see that depending on whether if you want to give the user a different print statement, 274 19:45.080 --> 19:49.250 based on their choice, then you would use if, elif, else, 275 19:49.250 --> 19:55.100 but if you actually just wanted to give them the same feedback, which is "Game Over", then you could 276 19:55.100 --> 19:56.870 just use if and else. 277 19:57.260 --> 20:01.130 Now let's run our game and just make sure that it works. 278 20:01.130 --> 20:04.580 So I'm going to go left because I know it continues. 279 20:04.580 --> 20:07.940 And then I'm going to wait for the boat. 280 20:07.940 --> 20:11.090 And that allows me to get to the final condition, 281 20:11.090 --> 20:13.760 and if I choose yellow, I know that I'll win. 282 20:13.760 --> 20:19.790 Now if you want to change the formatting, because having the input at the end of the sentence doesn't 283 20:19.790 --> 20:25.940 look as good as letting the user type it on a new line, then you can simply, if you remember, just 284 20:25.940 --> 20:33.440 add the new line which is \n at the end of your inputs, like so. 285 20:33.950 --> 20:37.010 So how did you get on with this challenge? 286 20:37.010 --> 20:42.730 And if you didn't manage to do it right, or if you've done it right, go back and try and modify it. 287 20:42.760 --> 20:48.940 See if you can add some more conditions, or see if you can make the "Game Over" messages a little bit 288 20:48.940 --> 20:50.740 more interesting than what I've written. 289 20:50.740 --> 20:54.070 See if you can modify and make it really your own. 290 20:54.340 --> 20:55.510 Have fun with that. 291 20:55.510 --> 21:01.120 And in the next lesson, I've got more exciting things coming up for you, so hopefully you've scheduled 292 21:01.120 --> 21:05.260 some time for tomorrow to complete the next day's lessons. 293 21:05.260 --> 21:07.390 But for now, it's good night from me.
