These are the user uploaded subtitles that are being translated: 1 00:00:00,120 --> 00:00:05,580 All right, guys, so now that we've loaded up all the knowledge that we need into our brains, it's 2 00:00:05,580 --> 00:00:08,730 time to tackle the final project of the day. 3 00:00:09,140 --> 00:00:14,460 And as I showed you in the beginning of the day, it's a Rock Paper Scissors game that we can play 4 00:00:14,460 --> 00:00:15,380 with the computer. 5 00:00:16,050 --> 00:00:22,170 So the game starts out by asking you to type 0 for rock, 1 for paper, or 2 for scissors. 6 00:00:22,420 --> 00:00:29,820 So let's go ahead and type two for scissors, and then it's going to show you a graphic of your choice scissors, 7 00:00:30,210 --> 00:00:35,730 and then the choice the computer made, which is rock. And of course, rock beats scissors 8 00:00:35,730 --> 00:00:36,870 so you lose. 9 00:00:37,380 --> 00:00:44,610 What this game boils down to is some way of randomly making a choice between rock, paper, or scissors 10 00:00:45,030 --> 00:00:50,970 and then comparing that choice that the computer randomly generated against your choice. 11 00:00:51,330 --> 00:00:57,450 And then based on the rules of rock, paper, and scissors, determining whether if you won, you lost or 12 00:00:57,450 --> 00:00:59,790 whether if you had a draw. 13 00:01:01,080 --> 00:01:06,570 While I was looking around, I actually came across the world rock paper scissors association. 14 00:01:07,440 --> 00:01:12,630 And they have the official rules of the state of Rock Paper Scissors. 15 00:01:13,200 --> 00:01:17,080 If you're not familiar with this game, it might be worth checking out this website. 16 00:01:17,610 --> 00:01:20,100 Here are the three shapes of rock, paper, scissors. 17 00:01:20,490 --> 00:01:27,330 And then the rules are that rock wins against scissors, scissors wins against paper, and paper wins 18 00:01:27,330 --> 00:01:28,440 against rock. 19 00:01:29,100 --> 00:01:36,420 Having all of this in mind, head over to replit/@appbrewery/ rock-paper-scissors-start 20 00:01:36,780 --> 00:01:40,170 and go ahead and just fork the starting project. 21 00:01:40,860 --> 00:01:47,700 Now you'll notice that in the starting project, I've already got the ASCII art for rock, paper and scissors 22 00:01:47,700 --> 00:01:50,870 in here and they're each saved to a variable. 23 00:01:51,390 --> 00:01:58,170 So what that means is that you can start out by just having a go at printing out let's say a rock. 24 00:01:59,040 --> 00:02:01,110 And remember that these are variable names. 25 00:02:01,110 --> 00:02:04,410 They're not strings, so they don't need the double quotes around them. 26 00:02:04,860 --> 00:02:05,910 So let's run that. 27 00:02:05,910 --> 00:02:12,450 And you can see what we get printed is the particular ASCII art that I chose in my print statement. 28 00:02:13,380 --> 00:02:16,080 So this is already yours. 29 00:02:16,080 --> 00:02:22,890 But as you'll notice, there's no other logic that I've provided you and you are going to rely on what 30 00:02:22,890 --> 00:02:28,650 you learned in the previous days and most importantly, what you've learned in today's lessons to be 31 00:02:28,650 --> 00:02:30,090 able to complete this challenge. 32 00:02:30,420 --> 00:02:36,330 And it's worth comparing the outcome against the game of Rock Paper Scissors that I'll link to. 33 00:02:37,200 --> 00:02:42,030 There's a couple of things to think about, namely, how are you going to decide who won or who lost? 34 00:02:42,330 --> 00:02:49,170 How are you going to get the computer to choose a random shape, rock, paper, scissors, and how you 35 00:02:49,170 --> 00:02:54,420 actually get this game to work in the same way that is demoed in this final version? 36 00:02:55,320 --> 00:02:59,400 I'm going to go quiet now and I'm going to let you pause the video. 37 00:02:59,790 --> 00:03:04,980 And I want you to spend at least ten or fifteen minutes working on this. 38 00:03:05,250 --> 00:03:10,170 And if you get stuck, just try some things out or maybe watch some of the previous videos in the day 39 00:03:10,470 --> 00:03:12,840 and just try to give it your best 40 00:03:12,840 --> 00:03:15,120 go, and do a lot of struggling. 41 00:03:15,510 --> 00:03:16,950 Hopefully you're going to succeed. 42 00:03:16,950 --> 00:03:20,940 And once you're done, head back over here and I'll go through the solution with you. 43 00:03:21,180 --> 00:03:22,320 So pause the video now. 44 00:03:25,760 --> 00:03:30,860 All right, so we know that we've got all of this ASCII art, but for the moment, I'm just going to 45 00:03:30,860 --> 00:03:35,150 start off by putting down the basic logic of this game. 46 00:03:35,570 --> 00:03:41,840 And it's really helpful for you as well if you start thinking about breaking down the larger problem, 47 00:03:41,840 --> 00:03:47,930 which is making the Rock Paper Scissors game into smaller problems that you can solve, like generating 48 00:03:47,930 --> 00:03:50,110 a random number between one and three. 49 00:03:50,420 --> 00:03:55,820 So we have some sort of proxy for Rock Paper Scissors. And then maybe thinking about putting down 50 00:03:55,820 --> 00:04:02,360 the logic, well, if the computer chose scissors and I chose paper, then I'm going to lose. 51 00:04:02,690 --> 00:04:07,150 Or if the computer chose rock and I chose paper, then I'm going to win. 52 00:04:07,550 --> 00:04:14,270 And putting that down on a flowchart using draw.io or something like that can make this challenge a lot 53 00:04:14,270 --> 00:04:15,350 easier as well. 54 00:04:16,580 --> 00:04:22,100 But without further ado, the first thing I need to do is to produce a user choice. 55 00:04:22,610 --> 00:04:28,120 Now, this is going to be the one that the user chose when they typed in a value. 56 00:04:28,610 --> 00:04:32,900 And in order to get the value from them, I'm going to need to use a input. 57 00:04:33,440 --> 00:04:40,610 And inside the input, I'm going to put the following prompt asking the user, what do you choose? 58 00:04:40,610 --> 00:04:44,180 Type 0 for rock, 1 for paper or 2 for scissors. 59 00:04:44,750 --> 00:04:51,140 Now, once I get hold of this input, hopefully, if the user is following my instructions, they're going 60 00:04:51,140 --> 00:04:54,610 to type some sort of number, either zero or one or two. 61 00:04:55,190 --> 00:05:01,130 Now that I've gotten hold of what the user wants to choose, the next thing to do is figure out what 62 00:05:01,130 --> 00:05:02,690 the computer is going to choose. 63 00:05:03,080 --> 00:05:09,050 So I'm going to make another variable called computer_choice and I'm going to generate a random number. 64 00:05:09,410 --> 00:05:13,070 So to do that, remember, we have to import the random module. 65 00:05:15,020 --> 00:05:22,250 And then we can start using it to generate random whole numbers by using random.randint. 66 00:05:23,090 --> 00:05:30,170 And then the range is going to be between zero and two, because this is what I asked the user to do. 67 00:05:30,170 --> 00:05:33,190 Type 0 for rock, 1 for paper, 2 for scissors. 68 00:05:33,530 --> 00:05:37,850 So the computer is also going to choose between 0, 1 or 2. 69 00:05:39,110 --> 00:05:44,870 Now that I've got the computer_choice, I'm actually going to just print it out for now instead of printing 70 00:05:44,870 --> 00:05:48,860 out the actual shape, I'm just going to print out the number. 71 00:05:48,890 --> 00:05:54,680 So computer chose and then let's go ahead and add a fstring. 72 00:05:57,020 --> 00:06:00,300 And of course, that requires the F in front of the string. 73 00:06:01,130 --> 00:06:07,130 So now if we just play the game as it is, remember that testing up while you're developing it is really, 74 00:06:07,130 --> 00:06:08,150 really good practice. 75 00:06:08,360 --> 00:06:14,120 It picks up on the bugs that you make along the way instead of waiting until the end when you've done 76 00:06:14,120 --> 00:06:14,540 everything 77 00:06:14,540 --> 00:06:18,500 and then it doesn't work and you have to untangle all of the lines of code. 78 00:06:19,160 --> 00:06:24,200 At this point, I've already realized that it's actually not so great getting the user to type on this 79 00:06:24,200 --> 00:06:24,670 line. 80 00:06:25,460 --> 00:06:29,940 What I would much rather is to start a new line for them to type their answer on. 81 00:06:30,560 --> 00:06:34,040 So if I run the code again, then it should look a bit like this. 82 00:06:34,040 --> 00:06:37,970 My prompt is now here. So I'm going to choose 0 for Rock. 83 00:06:38,510 --> 00:06:41,840 And then it tells me that computer also chose zero. 84 00:06:42,290 --> 00:06:44,000 So in this case, this would be a draw. 85 00:06:44,450 --> 00:06:49,730 But if I played this game again, you can see that the computer is probably going to choose something 86 00:06:49,730 --> 00:06:50,260 different. 87 00:06:50,450 --> 00:06:51,860 So I chose rock again 88 00:06:51,860 --> 00:06:54,140 the computer chose 1, which is paper. 89 00:06:54,950 --> 00:07:02,960 So now we can start thinking about how do we compare these two choices and how can we define the logic 90 00:07:02,960 --> 00:07:04,610 of Rock Paper Scissors? 91 00:07:05,240 --> 00:07:12,230 So I know that paper beats rock, scissors beats paper and rock will beat scissors. 92 00:07:12,680 --> 00:07:21,280 So if zero is rock, one is paper and two is scissors, then two beats one and one beats zero. 93 00:07:21,590 --> 00:07:28,010 So that's very simple for us to check in terms of using if statements, 94 00:07:28,010 --> 00:07:28,280 right? 95 00:07:28,280 --> 00:07:29,930 We could simply just check 96 00:07:30,410 --> 00:07:40,550 well, if the computer choice is greater than the user choice, well then this probably means that the 97 00:07:40,760 --> 00:07:42,350 computer wins. 98 00:07:43,590 --> 00:07:51,810 But this is not true in all cases, right? Because if the computer chose 2 for scissors and the user 99 00:07:51,810 --> 00:07:57,240 chose 0 for rock, then the user should win rather than the computer winning. 100 00:07:57,450 --> 00:08:01,880 So we actually have some exceptions to this rule. 101 00:08:02,790 --> 00:08:08,520 How can we catch the exceptions before we go down to this level of generalization? 102 00:08:09,240 --> 00:08:16,830 Well, we could instead of using this as an if, we use this as an elif and we create another if statement 103 00:08:16,830 --> 00:08:27,210 which says, well, if the user_choice is equal to zero, so if the user chose rock and the computer_choice 104 00:08:27,660 --> 00:08:34,170 was 2, well then this means that in this case, the user actually wins. 105 00:08:35,950 --> 00:08:41,140 Now, if we're thinking from the perspective of the user when they're playing this game, then they 106 00:08:41,140 --> 00:08:47,430 don't really care if the computer won or the user won. They want to know, did they win or did they lose? 107 00:08:47,890 --> 00:08:50,080 So let's change this wording a little bit. 108 00:08:50,350 --> 00:08:54,930 We'll say, instead of user wins, we'll say you win. 109 00:08:56,020 --> 00:09:00,730 And if the computer wins, then we'll say you lose. 110 00:09:01,690 --> 00:09:10,510 So now if we run our program and test it out, so let's say I'm going to type 0 for rock and the 111 00:09:10,510 --> 00:09:14,590 computer chooses 2, but we actually get an error. 112 00:09:14,740 --> 00:09:22,770 It tells us that the greater than comparison is not supported between instances of int and string. 113 00:09:23,200 --> 00:09:24,100 What's going on here? 114 00:09:24,310 --> 00:09:32,830 Well, remember that we get our inputs as a number, but the input is always going to be a string. 115 00:09:33,340 --> 00:09:34,900 So if we want this to be a number, 116 00:09:34,900 --> 00:09:37,910 then we're going to have to wrap it inside an int. 117 00:09:38,500 --> 00:09:41,020 So now we turn it into a whole number. 118 00:09:42,070 --> 00:09:43,880 Now, this might be a good point to address 119 00:09:43,900 --> 00:09:49,950 well, what should happen if they typed something that wasn't 0, 1 or 2, whether they typed 34? 120 00:09:50,440 --> 00:09:52,780 Well, then naturally they should probably lose, 121 00:09:52,780 --> 00:09:53,070 right? 122 00:09:53,290 --> 00:10:01,060 So we can add an else statement addressing this situation. So we could say else we just print 123 00:10:01,360 --> 00:10:04,310 You typed an invalid number. 124 00:10:05,020 --> 00:10:07,480 You lose. Cool. 125 00:10:07,540 --> 00:10:08,690 So that sorts that out. 126 00:10:09,100 --> 00:10:13,060 Now let's run our code again and see if it works. 127 00:10:13,270 --> 00:10:13,990 What do you choose? 128 00:10:13,990 --> 00:10:15,130 Type 0 for Rock. 129 00:10:15,160 --> 00:10:16,440 I'm going to choose rock again. 130 00:10:16,960 --> 00:10:21,970 Computer chose zero and it tells me that you typed an invalid number. 131 00:10:22,960 --> 00:10:26,000 Well, actually, zero is not an invalid number. 132 00:10:26,020 --> 00:10:27,280 So what's going on here? 133 00:10:27,820 --> 00:10:30,930 Well, it's because it didn't fit this criteria. 134 00:10:31,630 --> 00:10:32,830 So I had zero, 135 00:10:32,830 --> 00:10:39,530 computer had zero, and it didn't fit this criterion because zero is not greater than zero. 136 00:10:40,000 --> 00:10:43,720 So it basically defaulted to the final else statement. 137 00:10:44,440 --> 00:10:48,350 But what's actually happening here is that that was a draw. 138 00:10:48,940 --> 00:10:50,050 Computer chose rock, 139 00:10:50,050 --> 00:10:50,940 I chose rock. 140 00:10:51,100 --> 00:10:55,840 That's a draw in the official rules of Rock Paper Scissors. 141 00:10:56,620 --> 00:10:58,660 So how do I catch that? 142 00:10:58,690 --> 00:11:05,650 Well, I could create another elif statement which says, well, if the computer_choice is equal to 143 00:11:05,650 --> 00:11:08,610 the user_choice, well, then we're going to print 144 00:11:09,520 --> 00:11:10,690 it's a draw. 145 00:11:12,130 --> 00:11:17,680 Now, let's test our app again and see if there are any other situations where our code is not behaving 146 00:11:17,680 --> 00:11:18,250 properly. 147 00:11:19,030 --> 00:11:23,350 I'm going to choose rock again, computer chose rock as well. 148 00:11:23,560 --> 00:11:26,150 And I guess it's a draw, so that's pretty good. 149 00:11:27,850 --> 00:11:33,970 Now, if I choose 0 and the computer chose 2, then this is going to be the statement that gets 150 00:11:33,970 --> 00:11:35,830 triggered and I win. 151 00:11:35,980 --> 00:11:37,030 So that's pretty good. 152 00:11:37,960 --> 00:11:44,030 Now, what if I chose 2 for scissors and the computer chose 0? 153 00:11:44,980 --> 00:11:48,270 Well, in this case, rock beats scissors 154 00:11:48,280 --> 00:11:50,770 so it should actually say I lose. 155 00:11:51,310 --> 00:11:54,250 But instead it says you typed an invalid number. 156 00:11:54,640 --> 00:12:02,260 So it defaulted to the else statement again because this particular situation is not caught by any of 157 00:12:02,260 --> 00:12:03,070 these statements. 158 00:12:03,940 --> 00:12:05,590 So what do we have to do instead? 159 00:12:06,070 --> 00:12:15,250 Well, we actually need another elif to say, well, if the computer_choice was equal to 0 and 160 00:12:15,250 --> 00:12:21,510 the user_choice was equal to 2, well, this means that rock beats scissors 161 00:12:21,760 --> 00:12:25,480 so I lose and the computer wins. 162 00:12:26,320 --> 00:12:30,040 Now, the final one that we need to catch is this case. 163 00:12:30,640 --> 00:12:39,430 If I type 1 for paper and computer chooses 0 for rock, it again defaults to the else statements 164 00:12:40,120 --> 00:12:43,870 whereas in fact in this case it should tell me that I won. 165 00:12:44,500 --> 00:12:45,820 So what's missing here? 166 00:12:46,090 --> 00:12:49,740 Well, it's the partner to this particular statement. 167 00:12:50,350 --> 00:12:54,360 If computer_choice is greater than user_choice then I lose. 168 00:12:54,700 --> 00:13:02,680 But on the other hand, if the user_choice was greater than the computer_choice, then I actually should 169 00:13:02,680 --> 00:13:03,070 win. 170 00:13:05,730 --> 00:13:15,480 So now the final thing we might have to fix is this else statement now actually never gets called because 171 00:13:15,480 --> 00:13:16,980 this is what happens. 172 00:13:17,430 --> 00:13:20,460 So let's say that I choose 456. 173 00:13:20,910 --> 00:13:23,730 It tells me that computer chose 2, I win. 174 00:13:24,060 --> 00:13:24,930 What's happening here? 175 00:13:24,960 --> 00:13:29,970 Well, it's actually this particular line that's being carried out. 176 00:13:29,970 --> 00:13:32,320 user_choice is greater than computer_choice. 177 00:13:32,820 --> 00:13:34,080 This is not what we want. 178 00:13:34,090 --> 00:13:35,910 We want it to default to 179 00:13:36,210 --> 00:13:37,650 You typed an invalid number. 180 00:13:37,650 --> 00:13:42,690 You lose. So we can actually just use else in this situation. 181 00:13:43,260 --> 00:13:45,540 We actually need to provide a condition. 182 00:13:46,380 --> 00:13:54,610 We're going to use elif to check if the user_choice is greater or equal to three, 183 00:13:55,500 --> 00:13:59,910 now, the computer will never choose anything other than 0, 1 and 2 184 00:13:59,910 --> 00:14:01,530 so we don't have to check that one. 185 00:14:01,800 --> 00:14:06,230 But the user could choose something above 3 or below 0. 186 00:14:06,450 --> 00:14:14,530 So we can use an or statement to catch this. Or if the user_choice is less than zero, 187 00:14:15,180 --> 00:14:18,900 well, in this case, you typed an invalid number, you lose. 188 00:14:19,740 --> 00:14:22,110 But that's not all that we have to do. 189 00:14:22,410 --> 00:14:29,760 If we hit run and we again type some extraordinarily large number, you'll see that it still says 190 00:14:29,760 --> 00:14:31,230 computer chose 1. 191 00:14:31,230 --> 00:14:32,040 You win. 192 00:14:32,520 --> 00:14:33,240 What's going on? 193 00:14:33,240 --> 00:14:39,290 We have this statement that should catch this situation, but it's right at the bottom. 194 00:14:39,510 --> 00:14:44,370 So it's not going to be checked until one of the previous ones are checked. 195 00:14:44,880 --> 00:14:48,720 Namely, it's one of these that's going to be the problem. 196 00:14:49,260 --> 00:14:57,240 So what we have to do is we have to move this statement above all the lines so that we first check if 197 00:14:57,240 --> 00:15:02,390 the user_choice is greater than three or less than zero. 198 00:15:03,060 --> 00:15:08,850 And if that's not true, do we actually continue checking to see who won the game. 199 00:15:09,750 --> 00:15:16,830 Now, finally, we can run our code type an invalid number and get you typed an invalid number. You lose. 200 00:15:18,120 --> 00:15:24,600 So now that we've actually got our logic all sorted out, the next step is to include our images. 201 00:15:25,320 --> 00:15:29,340 And to do that, we have to somehow match it up with these numbers we have, 202 00:15:29,340 --> 00:15:30,870 right? 0, 1 and 2. 203 00:15:31,590 --> 00:15:36,870 Now, there's many, many ways that you could do this and you could solve this project. 204 00:15:37,230 --> 00:15:45,540 But the easiest way is probably putting the game images into a list where we have rock as the first 205 00:15:45,540 --> 00:15:50,170 one, paper as the second one and scissors as the last one. 206 00:15:50,640 --> 00:15:58,410 So we're using the fact that lists have a order that is always going to be followed. So we can now get 207 00:15:58,410 --> 00:16:02,060 hold of the rock picture by getting game_images[0]. 208 00:16:02,400 --> 00:16:09,570 We can get scissors by doing game_images[2] and so on and so forth. And we can match those up to our 209 00:16:09,570 --> 00:16:12,210 choices, the user_choice and the computer_choice. 210 00:16:12,810 --> 00:16:20,790 So when the user chooses a number, then we're going to print from the game_images and we're going to 211 00:16:20,790 --> 00:16:26,340 use our little square brackets to select the image we want from this list. 212 00:16:26,790 --> 00:16:31,140 And the one that we want is going to be based on the user's choice, right? 213 00:16:31,320 --> 00:16:33,630 0 for rock, 1 for paper, 2 for scissors. 214 00:16:33,960 --> 00:16:42,600 So we're going to put user_choice as the index to pick out an image from game_images. Now down here for 215 00:16:42,600 --> 00:16:49,950 the computer_choice, instead of printing the number that the computer chose, I'm going to delete that 216 00:16:49,950 --> 00:16:51,480 and add a little colon. 217 00:16:52,680 --> 00:16:56,550 So that way it's going to show computer chose 218 00:16:56,910 --> 00:17:02,130 and then I'm going to print the image of the choice that the computer made. 219 00:17:02,520 --> 00:17:04,290 So I'm going to add another print statement, 220 00:17:04,560 --> 00:17:10,890 I'm going to tap into the game_images and then inside some square brackets, I'm going to use the computer 221 00:17:11,130 --> 00:17:17,820 choice which is going to be between 0, 1 and 2 as the index to pick out the corresponding image 222 00:17:18,180 --> 00:17:20,340 from my list game_images. 223 00:17:20,930 --> 00:17:28,170 So now we're finally ready to run our code and I'm going to choose 0 for rock and the computer chose 224 00:17:28,170 --> 00:17:28,920 paper. 225 00:17:29,220 --> 00:17:31,920 So paper beats rock, I lose. 226 00:17:32,790 --> 00:17:33,840 Let's try this again. 227 00:17:33,840 --> 00:17:37,860 I'm going to choose scissors and computer chose scissors. 228 00:17:37,860 --> 00:17:42,090 It's a draw. But we have also introduced a bug. 229 00:17:42,690 --> 00:17:47,730 So if we test this using a number that's outside of this range, 0, 1 or 2, 230 00:17:47,730 --> 00:17:51,330 so let's try 5. And we hit enter, 231 00:17:51,330 --> 00:17:52,020 what do we get? 232 00:17:52,050 --> 00:17:53,970 We get a index error. 233 00:17:54,480 --> 00:17:56,110 So what has happened here? 234 00:17:56,250 --> 00:17:58,680 Well, this is up to you to debug. 235 00:17:59,070 --> 00:18:02,970 Well, this is a really good opportunity for you to practice your debugging. 236 00:18:03,300 --> 00:18:04,620 So think about what has 237 00:18:04,730 --> 00:18:12,280 changed since the last time we tested this and how you can fix the code so that it works as expected, 238 00:18:12,590 --> 00:18:18,290 so telling us that you typed an invalid number, you lose whenever we type a number that's above or 239 00:18:18,290 --> 00:18:20,360 equal to three or less than zero. 240 00:18:20,840 --> 00:18:25,880 So I want you to pause the video and see if you can debug this challenge so that when you type in 5, 241 00:18:26,090 --> 00:18:29,330 you get this printed. Pause video now. 242 00:18:32,680 --> 00:18:39,070 All right, so what's going on here, because we tested this and it worked, but in between that time, 243 00:18:39,070 --> 00:18:46,480 we also added this line because we wanted to get a hold of the game images based on the user's choice. 244 00:18:46,930 --> 00:18:51,490 Now, at this point, the user's choice is unchecked by the if statement. 245 00:18:51,850 --> 00:18:56,110 So it could still be equal to 4 or 5 or 10 or a million. 246 00:18:56,560 --> 00:19:04,300 So if in that case, it tries to get hold of the fifth image from the game_images list, well, it doesn't 247 00:19:04,300 --> 00:19:04,690 exist. 248 00:19:04,810 --> 00:19:06,850 There's only 0, 1 and 2. 249 00:19:07,750 --> 00:19:14,500 So to fix this, we need to move this if statement so that it gets checked before this line of code 250 00:19:14,500 --> 00:19:15,370 gets carried out. 251 00:19:15,940 --> 00:19:22,330 So let's go ahead and cut this line of code out and put it right above this print statement. 252 00:19:22,840 --> 00:19:30,340 So in this case, if the user types in a choice that's above or equal to three or less than zero, 253 00:19:30,670 --> 00:19:32,020 we're going to print this. 254 00:19:32,440 --> 00:19:38,670 But else, if they typed in any other number, then we want the rest of the code to continue. 255 00:19:39,010 --> 00:19:44,070 So let's select the rest of the code, hit tab and tab it over 256 00:19:44,080 --> 00:19:46,510 so that is included under the else statement. 257 00:19:47,050 --> 00:19:54,010 Now let's go ahead and change this from elif just to an if because we're no longer checking it as another 258 00:19:54,010 --> 00:19:54,430 else- 259 00:19:54,430 --> 00:19:56,890 if statement. It is just a straight up 260 00:19:56,890 --> 00:20:05,590 if. So, in this case, if they typed a 5, then it will go into this basket and it will finish there. 261 00:20:05,890 --> 00:20:10,670 But otherwise, it will go into this basket and it will continue checking later on. 262 00:20:11,260 --> 00:20:14,570 So did you manage to debug your code and figure out the issue? 263 00:20:15,040 --> 00:20:17,320 This is one of the most important skills 264 00:20:17,320 --> 00:20:21,760 as a programmer. You have plenty of opportunities coming up to practice your debugging. 265 00:20:22,330 --> 00:20:27,790 And if you ever want more practice, head over into the Q&A and see what other students have issues 266 00:20:27,790 --> 00:20:31,810 with and see if you can help them out by practicing your debugging skills. 267 00:20:32,590 --> 00:20:40,570 Now, we have completed the project by using everything from lists to randomization to variables to 268 00:20:40,570 --> 00:20:43,370 if statements and a whole lot of logic. 269 00:20:43,630 --> 00:20:47,660 So how did you get on with this project? If you struggle 270 00:20:47,680 --> 00:20:54,970 this is the time again to go back to it and maybe map things out using a flow diagram or try to run 271 00:20:54,970 --> 00:20:59,080 the code using Thonny to see how it does it step by step. 272 00:20:59,590 --> 00:21:04,180 But the important thing is that you got to write your own code and you got to make it work. 273 00:21:04,420 --> 00:21:09,580 And this is the only way that you'll understand what's going on so that you can continue on. 274 00:21:09,910 --> 00:21:15,670 And as things get harder, you'll be able to learn more because you've already understood all of the 275 00:21:15,670 --> 00:21:16,570 previous knowledge. 276 00:21:17,320 --> 00:21:19,150 So I hope you had fun with me today 277 00:21:19,150 --> 00:21:24,550 learning and building, and hopefully I will see you tomorrow bright and early. 278 00:21:24,880 --> 00:21:27,100 So that's good night from me for today. 29198
