WEBVTT 0 00:00.170 --> 00:00.620 All right. 1 00:00.620 --> 00:02.870 We are very much now in the home stretch. 2 00:02.870 --> 00:07.190 We are on the last step, Step Number 5 of five. 3 00:07.190 --> 00:11.090 And we're going to complete this game in this lesson. 4 00:11.090 --> 00:18.440 So when you open up the starting file in the main.py, you will notice that there are a bunch of errors. 5 00:18.440 --> 00:20.750 And this is intentional. 6 00:20.750 --> 00:27.080 Now what's happened is I have deleted the list called stages. 7 00:27.080 --> 00:36.680 I have deleted the list called word_list, and instead, I want you to get them from these files hangman_art, 8 00:36.710 --> 00:42.650 and hangman_words just so that we can practice using other modules. 9 00:42.650 --> 00:46.010 And this is something we learned in previous lessons as well. 10 00:46.010 --> 00:53.120 So if you forgot, then take a look at Python modules when we introduced the Random Module. 11 00:53.660 --> 01:02.240 So that tackles TODO Number 1, TODO Number 2, and TODO Number 3, which is to basically 12 01:02.240 --> 01:08.870 use what you've learned about importing modules in order to bring in those things that we need for 13 01:08.870 --> 01:10.730 our code to function correctly. 14 01:10.880 --> 01:19.490 Now the next few TODOs are mostly to do with tidying up the logic and also just making our app a little 15 01:19.490 --> 01:20.930 bit easier to use. 16 01:20.960 --> 01:27.890 You'll notice I've added some extra bits in here, like some asterisks, just to make each section when 17 01:27.890 --> 01:31.160 they lose, or when they win a little bit more obvious. 18 01:31.160 --> 01:38.930 And in Step 4, I want you to give the user some feedback to improve our user experience. 19 01:38.930 --> 01:44.540 So if the user has entered a letter that they've already guessed, we need to tell them, "You already 20 01:44.540 --> 01:47.810 guessed this." And we'll print that letter and let them know. 21 01:47.810 --> 01:52.010 But we're not going to deduct any lives because I think that's maybe a little bit unfair. 22 01:52.010 --> 01:56.690 So an example is you've already guessed letter a, something like this. 23 01:56.690 --> 02:01.130 Now TODO Number 5 is on a similar vein. 24 02:01.130 --> 02:05.960 If the letter they guessed is not in the chosen_word, we're going to print it out and let them know. 25 02:05.960 --> 02:07.460 So give them some feedback. 26 02:07.460 --> 02:10.100 For example, "You guessed d, that's not in the word. 27 02:10.100 --> 02:14.210 You lose a life." Just so they know exactly what's going on in the game. 28 02:14.780 --> 02:22.040 And the final TODO, TODO Number 6, is to update this print statement so that we give the user an indication 29 02:22.040 --> 02:23.900 of how many lives they have left. 30 02:23.900 --> 02:27.500 So it'll be 4 / 6 lives left, then 3 / 6 lives left, 31 02:27.500 --> 02:35.930 So each time we rerun our while loop, they know how close they are to the end and give them a little 32 02:35.930 --> 02:39.440 bit more danger and anticipation. 33 02:39.440 --> 02:45.080 So these TODOs are a lot easier than previous ones, and I think you'll be able to tackle them just 34 02:45.080 --> 02:45.440 fine. 35 02:45.440 --> 02:48.860 So pause the video and complete your project. 36 02:51.860 --> 02:52.430 Okay. 37 02:52.430 --> 02:55.430 Let's start with TODO Number one. 38 02:55.430 --> 03:00.160 So you might remember that we can simply import any module, 39 03:00.160 --> 03:03.880 and this module is called hangman_words. 40 03:03.880 --> 03:05.470 And it looks like this, 41 03:05.500 --> 03:09.490 it contains just a single list called word_list. 42 03:09.490 --> 03:11.290 So we can do it in two ways, 43 03:11.290 --> 03:14.860 we can do it the usual way, which is how we imported random. 44 03:14.860 --> 03:19.720 So we import the module which is hangman_words, 45 03:19.720 --> 03:25.210 and then we can use it inside our file. 46 03:25.210 --> 03:32.650 So here when we're using word_list, to get rid of this red underline, we can say hangman_words.word_list 47 03:32.650 --> 03:33.130 . 48 03:33.130 --> 03:37.210 And then Python will be able to find this file because it's imported. 49 03:37.210 --> 03:40.270 And then find this word_list that we need. 50 03:40.270 --> 03:48.070 Another way of doing imports is a way where you can avoid using these dots and makes the code just a 51 03:48.070 --> 03:49.090 little bit tighter. 52 03:49.090 --> 03:53.620 So instead of just writing import hangman_words, you can say from 53 03:55.750 --> 04:03.700 this module called, hangman_words, import this one thing, which is the words_list. 54 04:03.730 --> 04:08.710 Now of course, if you have lots of things to import from a particular file or module, then this is 55 04:08.710 --> 04:10.150 going to be a little bit painful, 56 04:10.150 --> 04:17.950 but in our case, when there's only very few and we only want to import one or two things, then this syntax 57 04:17.950 --> 04:20.860 can make it a lot lighter. 58 04:20.860 --> 04:26.680 And it means we don't have to write hangman_words.word_list every time we want to use it, which 59 04:26.680 --> 04:28.120 can be a bonus. 60 04:28.120 --> 04:30.700 Now, of course, you might not have seen it this way. 61 04:30.700 --> 04:34.090 So if you complete it the other way, it's also perfectly valid, 62 04:34.090 --> 04:37.870 and in most situations, that's exactly how you want to do it. 63 04:37.900 --> 04:38.380 All right. 64 04:38.380 --> 04:42.430 Let's go ahead and knock off TODO Number 2, and TODO Number 3. 65 04:42.430 --> 04:46.600 So TODO Number 2 we just need to do the same thing and import. 66 04:46.600 --> 04:52.960 So from hangman_art, we're going to import the list called stages, 67 04:52.960 --> 04:57.010 and then that gets rid of that error right there. 68 04:57.010 --> 05:05.050 And TODO Number 3 we need to import the logo which we've got right here called, logo. 69 05:05.050 --> 05:09.790 And this just means that when we start up our game it will display a nice little logo. 70 05:09.790 --> 05:13.870 So we'll just print and we're going to print the logo. 71 05:13.870 --> 05:16.540 And then we're going to import the logo. 72 05:16.540 --> 05:20.440 So we can also add a new from whatever, 73 05:20.440 --> 05:25.660 but it's actually much easier to add a comma and just add logo afterwards. 74 05:25.660 --> 05:30.880 So this way you save yourself a little bit of code. 75 05:30.880 --> 05:35.170 But if you wrote it like this, hangman_art.logo, 76 05:35.200 --> 05:37.960 that is also perfectly valid. 77 05:38.050 --> 05:43.720 Now Step Number 4 is when the user has entered a letter they've already guessed, 78 05:43.720 --> 05:45.940 we're going to print the letter and let them know. 79 05:45.940 --> 05:50.410 So this is the example and I'm going to use it. 80 05:50.410 --> 05:57.940 So if the guess, so the letter that we're guessing right now is in, 81 05:57.940 --> 06:04.450 so the 'in' keyword, to check if it exists inside the set of correct_letters, 82 06:04.450 --> 06:09.160 well, then that means that they previously already guessed that letter. 83 06:09.160 --> 06:16.870 So we need to let them know, print that they've already guessed that letter. So we can copy this 84 06:16.870 --> 06:24.190 line and paste it in here and use an f-string to insert the guess right there. 85 06:24.280 --> 06:28.480 So now if we go ahead and run our file as it is, you'll see, 86 06:28.510 --> 06:31.810 firstly, we get our nice little Hangman logo printing. 87 06:31.810 --> 06:38.440 And I've got the chosen_word still printing right now because otherwise, it's impossible to test this. 88 06:38.440 --> 06:41.710 I'm not good enough at Hangman to be able to do this. 89 06:42.010 --> 06:45.910 So we've got our word to guess, and then we have to guess a letter, 90 06:45.910 --> 06:51.490 So I'm going to guess r, and you can see if I guess r again I don't lose a life, 91 06:51.490 --> 06:57.670 and it just tells me that I've already guessed r. So that works as expected. 92 06:57.970 --> 07:04.360 Moving on to the next TODO if the letter is not in the chosen_word, then we're going to print it out 93 07:04.360 --> 07:05.800 and let them know. 94 07:05.800 --> 07:11.020 So it's important to give user feedback because that improves the user experience. 95 07:11.020 --> 07:17.860 Now there's a lot of science and art to user experience, but it's good to start thinking about this 96 07:17.860 --> 07:20.470 even as we're learning the basics of Python. 97 07:21.400 --> 07:30.580 So if the letter is not in the chosen_word, so that is under this if statement, then we're going to 98 07:30.580 --> 07:32.860 reduce their lives by 1, 99 07:32.860 --> 07:36.280 but we're also going to add this print statement. 100 07:36.280 --> 07:39.640 So I'm going to copy the example as it is. 101 07:39.640 --> 07:48.160 And then I'm going to paste it into this if statement and replace this with an f-string, which is the 102 07:48.160 --> 07:56.920 {guess}. And very thankfully, Python automatically adds this f in here because I'm using PyCharm and 103 07:56.920 --> 07:59.470 it's a really, really helpful code editor. 104 07:59.470 --> 08:02.800 But just be aware that that's what's happening just now. 105 08:03.160 --> 08:10.780 Moving on to TODO Number 6, we're going to update this part, this print statement to tell the user 106 08:10.780 --> 08:17.020 how many lives they have left so that each time the while loop runs, they can see how many lives they 107 08:17.020 --> 08:19.840 have left 4/6, 3/6, 2/6, 108 08:19.840 --> 08:25.720 give them a little bit of a feeling of impending doom as any good game should do. 109 08:25.720 --> 08:27.760 If you play Elden Ring, you'll know what I mean. 110 08:27.940 --> 08:32.890 And inside here we're going to insert the variable called lives. 111 08:32.890 --> 08:35.200 And again, this should be an f-string. 112 08:35.200 --> 08:39.540 And we only have one more TODO left before we finish this game. 113 08:39.540 --> 08:45.390 So update this last print statement to give them the correct_word that they're trying to guess. 114 08:45.390 --> 08:48.900 It's never good to frustrate your users too much. 115 08:49.050 --> 08:55.350 I'm looking at you from software, the people who make Elden Ring and making it really difficult to 116 08:55.350 --> 08:56.640 pass all the levels, 117 08:57.030 --> 09:03.480 but here we want to be able to give the user the word that they've been trying to guess all along. 118 09:03.480 --> 09:07.920 So even if they don't get it and they lose, they at least know what it was. 119 09:07.920 --> 09:10.980 So we're going to again insert this as an f-string. 120 09:10.980 --> 09:20.490 And I'm just going to copy the format here in the TODO, telling them that it was this particular word, 121 09:20.490 --> 09:26.040 replacing this with the f-string, and my variable is called chosen_word. 122 09:26.040 --> 09:32.250 And now I have completed the entire project of Hangman. 123 09:32.250 --> 09:35.400 Now, I'm not saying that there's no more improvement. 124 09:35.400 --> 09:41.100 There's a lot of things that you could do to improve Hangman, and this is by no means a fully-fledged 125 09:41.100 --> 09:42.030 game. 126 09:42.330 --> 09:50.700 It is just an exercise to be able to test and revise some of the concepts you've learned about 127 09:50.700 --> 09:55.020 Python up to this point, and hopefully it was fun building it, 128 09:55.020 --> 09:59.070 and hopefully, you're going to have some fun playing it and showing it to friends. 129 09:59.100 --> 10:05.160 Now, there are a ton of more improvements that you can make to this game, and if you're up for it, 130 10:05.160 --> 10:09.570 then you can of course go ahead and make it to your heart's desire. 131 10:09.570 --> 10:12.570 Change it, or update the user experience, 132 10:12.570 --> 10:14.130 change the wording, 133 10:14.130 --> 10:19.770 give it more functionality, different functionality, whatever it is you want to do, the world is 134 10:19.770 --> 10:20.670 your oyster. 135 10:20.670 --> 10:25.410 But hopefully, you've managed to understand all of the code up to now, 136 10:25.410 --> 10:32.580 and if you don't, just try deleting everything and starting from the beginning until you make sure 137 10:32.580 --> 10:38.520 that every single concept in here that you've reviewed, either you've gone back to previous videos 138 10:38.520 --> 10:41.250 or you've looked up documentation, 139 10:41.250 --> 10:44.490 as long as everything makes sense before you proceed. 140 10:44.520 --> 10:52.200 I know it's really tempting to keep to the one day, a day kind of format, but the more important 141 10:52.200 --> 10:56.490 thing is that you're actually learning valuable skills and you're not just skipping ahead. 142 10:56.490 --> 11:02.670 So I hope this was fun, and I hope you'll look forward to building more stuff with me in future lessons, 143 11:02.670 --> 11:05.580 but right now, take a rest and well done.
