That way 5 00:00:14,160 --> 00:00:15,600 it actually becomes your own. 6 00:00:16,290 --> 00:00:21,090 These coding exercises are great because we can give you instructions and show 7 00:00:21,090 --> 00:00:25,200 you what should happen if you write the correct code, what it needs to do, 8 00:00:25,620 --> 00:00:29,220 and you'll be able to write your code as well as see it run in the console. 9 00:00:29,850 --> 00:00:33,750 And it's through a lot of these exercises that you're going to level up and 10 00:00:33,750 --> 00:00:37,170 you're going to become a better coder. So in order to enroll, 11 00:00:37,170 --> 00:00:40,650 head over to this URL, and if you don't want to type it in, 12 00:00:40,680 --> 00:00:44,220 you can head over to the course resources and you will be able to get a direct 13 00:00:44,220 --> 00:00:45,053 link there. 14 00:00:45,810 --> 00:00:50,280 And the first thing I want you to do is to go ahead and click on the fork 15 00:00:50,310 --> 00:00:53,310 button. Now, 16 00:00:53,370 --> 00:00:58,370 the important thing here is this is the output that we want to see down here in 17 00:00:58,770 --> 00:01:03,390 the console. And when you hit run, this is what should happen. Now, 18 00:01:03,420 --> 00:01:08,420 remember that I want you to have exactly the same characters printed out as I've 19 00:01:09,300 --> 00:01:13,620 got here, including where the spaces are, including the symbols, 20 00:01:13,860 --> 00:01:15,750 like these single quotes, et cetera. 21 00:01:16,260 --> 00:01:20,820 Now is the time for you to head over to this challenge and try to complete it. 22 00:01:21,900 --> 00:01:24,300 Pause the video now and complete this challenge. 23 00:01:24,440 --> 00:01:28,820 ... 24 00:01:28,910 --> 00:01:30,320 All right. How did you get on? 25 00:01:30,860 --> 00:01:34,700 I really hope that you gave this a good go because it's in these moments where 26 00:01:34,700 --> 00:01:37,150 you're going to be learning to code. Unfortunately, 27 00:01:37,220 --> 00:01:41,030 no amount of listening to me talk is actually going to give you these skills. 28 00:01:41,060 --> 00:01:45,590 It's only when you actually try it out and get the computer to do the thing that 29 00:01:45,590 --> 00:01:48,830 you want it to do. That's when you become the master of the computer, 30 00:01:49,040 --> 00:01:51,980 also known as the programmer. So in this case, 31 00:01:52,010 --> 00:01:53,510 the instructions are pretty simple. 32 00:01:53,660 --> 00:01:58,010 We have to use what we learned about the print statement to output these three 33 00:01:58,010 --> 00:02:00,230 lines. And notice how in this gif, 34 00:02:00,260 --> 00:02:03,140 the lines are printing out in separate lines. 35 00:02:03,650 --> 00:02:06,440 This one gets printed, then this one, then this one. 36 00:02:06,440 --> 00:02:08,270 But because it happens so fast, 37 00:02:08,510 --> 00:02:11,360 it seems as if they're getting printed as a single block. 38 00:02:11,900 --> 00:02:14,420 So we're told to write our code below this line. 39 00:02:15,230 --> 00:02:17,390 And we know that in order to print something, 40 00:02:17,420 --> 00:02:22,420 we use the print function with a set of parentheses. And inside the parentheses 41 00:02:22,910 --> 00:02:27,050 is where we tell it what we want it to print. So in the first instance, 42 00:02:27,080 --> 00:02:30,650 it's day one, a space, 43 00:02:30,710 --> 00:02:35,060 then it's... now it's really easy to make spelling mistakes, 44 00:02:35,360 --> 00:02:40,160 but I really encourage you to actually type out anything that you put into your 45 00:02:40,160 --> 00:02:44,360 code rather than just simply copying and pasting it. Now, 46 00:02:44,390 --> 00:02:49,390 of course, it works exactly the same way. I could just copy and paste the code in 47 00:02:50,300 --> 00:02:54,110 here, but it's often in these cases where you make mistakes, 48 00:02:54,170 --> 00:02:55,310 like for example, 49 00:02:55,520 --> 00:02:59,350 forgetting to add the double quotes around the text that you want to print. 50 00:03:00,010 --> 00:03:04,060 I really recommend just typing out the code for practice whenever you are doing 51 00:03:04,060 --> 00:03:06,670 these code challenges. Now, 52 00:03:06,730 --> 00:03:10,570 the last line that we want to print is a little bit complicated. 53 00:03:10,900 --> 00:03:12,730 It's almost like print inception, 54 00:03:13,030 --> 00:03:16,810 because what we want to print is this function. 55 00:03:16,930 --> 00:03:19,000 This is how we write our function. 56 00:03:19,600 --> 00:03:23,800 And that has to go inside here, inside a set of double-quotes. 57 00:03:24,190 --> 00:03:27,970 So let's open up a double-quote and then write our print statement. 58 00:03:28,540 --> 00:03:32,560 And in this case, I'm actually using a single quote 59 00:03:33,040 --> 00:03:36,310 and I'll tell you just in a little moment why that is. 60 00:03:37,180 --> 00:03:41,290 So let's add that single quote and finally, the closing parentheses. 61 00:03:41,710 --> 00:03:45,790 This now is the entire code that you would need to be able to print something 62 00:03:45,790 --> 00:03:48,670 out. And when I go ahead and click run, 63 00:03:48,700 --> 00:03:52,540 you can see that the output looks exactly the same as what we've got here in the 64 00:03:52,540 --> 00:03:57,400 GIF. This is what we want. And I've now completed the coding challenge. 65 00:03:58,060 --> 00:04:00,430 Now, coming back to this single quote, 66 00:04:00,520 --> 00:04:04,690 why is it that I've got a single quote here rather than a double quote, 67 00:04:04,720 --> 00:04:08,620 which is what we've been using all this time? Well, because in Python, 68 00:04:08,650 --> 00:04:13,650 it doesn't actually care whether if you enclose the strings, 69 00:04:13,900 --> 00:04:18,900 so these pieces of texts are not to be interpreted as code inside a single 70 00:04:19,330 --> 00:04:21,940 quotes or inside double quotes. 71 00:04:22,180 --> 00:04:26,830 It is identical to the computer. This Honeybadger literally doesn't care. 72 00:04:27,610 --> 00:04:32,610 But if you had a set of double quotes and then you wanted another set of double 73 00:04:33,790 --> 00:04:37,330 quotes inside the double quotes, so for example, 74 00:04:37,330 --> 00:04:41,710 if I replace this with double quotes, you'll see that already, 75 00:04:41,710 --> 00:04:46,270 the syntax highlighting is already screaming out to us. There's something that's not 76 00:04:46,270 --> 00:04:51,270 quite right here because the colors are not the same as here where the print 77 00:04:53,560 --> 00:04:56,050 function is in a particular color, 78 00:04:56,380 --> 00:05:00,550 the parentheses are in a particular color and the text that is to be printed 79 00:05:00,690 --> 00:05:04,210 is in a yet another different color. In this case, 80 00:05:04,210 --> 00:05:07,720 it looks all jumbled up and we're getting some errors here. 81 00:05:08,470 --> 00:05:11,980 So now if I hit run, you'll get syntax errors. 82 00:05:12,910 --> 00:05:15,220 And the problem here is of course, 83 00:05:15,640 --> 00:05:20,640 this-- is of course our code thinks that the end of this string is here. 84 00:05:22,810 --> 00:05:27,790 And so it doesn't know what on earth is going on afterwards. And instead, 85 00:05:27,820 --> 00:05:31,840 it's seeing this as a string, this as a string, 86 00:05:32,290 --> 00:05:35,380 and this is being interpreted as code. 87 00:05:36,400 --> 00:05:41,400 So when we want to use some double quotes inside another set of double quotes, 88 00:05:41,800 --> 00:05:46,450 commonly you'll see people switch to single quotes instead. 89 00:05:46,990 --> 00:05:51,130 So you could, for example, write the print statement like so, 90 00:05:51,580 --> 00:05:55,150 and use double quotes if you want to print those out, 91 00:05:55,720 --> 00:05:59,360 or you can do it the other way which is what I had before 92 00:05:59,780 --> 00:06:03,560 where we use our double quotes on the outside and single quotes on the inside. 93 00:06:04,070 --> 00:06:07,100 So have a play around with that if that's at all confusing, 94 00:06:07,460 --> 00:06:10,400 but once you've tried it a few times and switched it around a few times, 95 00:06:10,700 --> 00:06:12,800 it should become clear what it's actually doing. 96 00:06:13,580 --> 00:06:18,200 How did you get on with this challenge? If you ever need to see the solution, 97 00:06:18,230 --> 00:06:20,240 it's always down here as a link. 98 00:06:21,200 --> 00:06:24,230 So if I go ahead and paste that link into my browser, 99 00:06:24,260 --> 00:06:29,120 then you'll see, word for word, the solution to each of these challenges. 100 00:06:29,600 --> 00:06:32,990 And hopefully that'll help you along the way while you're learning as well. 101 00:06:33,740 --> 00:06:36,590 So I hope you enjoyed this challenge. In the next lesson, 102 00:06:36,710 --> 00:06:40,430 we're going to get back to learning about Python and we're going to learn about 103 00:06:40,490 --> 00:06:44,060 strings and string manipulation. For all of that, 104 00:06:44,300 --> 00:06:45,680 and more I'll tell you there. 10487
