1 00:00:00,000 --> 00:00:01,589 In this video we're gonna be talking about 2 00:00:01,589 --> 00:00:04,620 how we can use this ChatGPT for debugging. 3 00:00:04,620 --> 00:00:06,900 Now let's just go ahead and ask 4 00:00:06,900 --> 00:00:09,210 ChatGPT to create something for us 5 00:00:09,210 --> 00:00:11,730 and then we're gonna intentionally mess it up 6 00:00:11,730 --> 00:00:14,250 just to kind of simulate what it would've been like 7 00:00:14,250 --> 00:00:15,930 if we had written something ourselves 8 00:00:15,930 --> 00:00:17,130 that was maybe incorrect 9 00:00:17,130 --> 00:00:19,410 or missing a crucial line of code 10 00:00:19,410 --> 00:00:21,240 or a piece of logic that we just, 11 00:00:21,240 --> 00:00:24,210 'cause we're humans, we're subject to mistakes. 12 00:00:24,210 --> 00:00:25,860 Just maybe we just forgot about something, right? 13 00:00:25,860 --> 00:00:28,230 So let's see if ChatGPT can actually help us 14 00:00:28,230 --> 00:00:29,700 with the debugging process 15 00:00:29,700 --> 00:00:31,870 and kind of reading through our code 16 00:00:31,870 --> 00:00:33,870 with knowledge of the problem spec. 17 00:00:33,870 --> 00:00:35,220 And then just trying to figure out 18 00:00:35,220 --> 00:00:37,170 what could have possibly went wrong. 19 00:00:37,170 --> 00:00:40,587 So first let's ask it an interesting question. 20 00:00:40,587 --> 00:00:41,800 Let's see if, could you 21 00:00:43,140 --> 00:00:46,593 generate the Mandelbrot set? 22 00:00:48,750 --> 00:00:51,130 Or rather could you generate a visualization 23 00:00:52,200 --> 00:00:55,173 of the Mandelbrot set in Python? 24 00:00:56,250 --> 00:00:58,590 Now this is, so the, if you don't know, 25 00:00:58,590 --> 00:01:01,380 the Mandelbrot set is a fractal, 26 00:01:01,380 --> 00:01:04,200 which is basically when viewed, it's like 27 00:01:04,200 --> 00:01:07,230 infinite complexity as you continue to zoom in and zoom in 28 00:01:07,230 --> 00:01:09,510 and it's basically a mathematical function. 29 00:01:09,510 --> 00:01:12,030 And yeah, so it's able to do that. 30 00:01:12,030 --> 00:01:13,800 So if you go ahead and copy the code here, 31 00:01:13,800 --> 00:01:15,120 this is some beautiful code right here. 32 00:01:15,120 --> 00:01:17,820 It's literally telling us, it's giving us comments 33 00:01:17,820 --> 00:01:19,320 for everything and telling us what 34 00:01:19,320 --> 00:01:21,870 each and every line of code is doing. 35 00:01:21,870 --> 00:01:23,070 But yeah, let's go ahead 36 00:01:23,070 --> 00:01:25,950 and create a file for that real quick. 37 00:01:25,950 --> 00:01:27,520 So, Mandelbrot.py 38 00:01:28,830 --> 00:01:31,680 and, oh, I think I stole it when it was 39 00:01:31,680 --> 00:01:33,090 not done generating stuff. 40 00:01:33,090 --> 00:01:36,660 So let's go ahead and wait for that to finish writing. 41 00:01:36,660 --> 00:01:39,300 So now it's gonna go ahead and tell us what's going on. 42 00:01:39,300 --> 00:01:42,960 Generates a square image of the set with 500 by 500 pixels. 43 00:01:42,960 --> 00:01:46,080 So if we go and take that 44 00:01:46,080 --> 00:01:47,400 and we run it, let's see 45 00:01:47,400 --> 00:01:50,130 what it gives us without like kind of messing with anything. 46 00:01:50,130 --> 00:01:52,230 So we actually know what we're working with here. 47 00:01:52,230 --> 00:01:53,680 Well, that looks really cool. 48 00:01:54,870 --> 00:01:56,490 Yeah, so that's the Mandelbrot set. 49 00:01:56,490 --> 00:01:58,500 I can go ahead and zoom in here. 50 00:01:58,500 --> 00:02:02,820 As you can see, it's a, it's not really infinitely detailed 51 00:02:02,820 --> 00:02:05,280 as I've not made the size too large, 52 00:02:05,280 --> 00:02:07,050 but that's something I can tweak here. 53 00:02:07,050 --> 00:02:09,810 Let's see if we can kind of mess with this thing, right? 54 00:02:09,810 --> 00:02:12,090 So this is like a very crucial part of the math here. 55 00:02:12,090 --> 00:02:16,053 So if I, let's say mess with this, let's say 1. 56 00:02:16,980 --> 00:02:20,010 I'm, I'm interested in what this will look like. 57 00:02:20,010 --> 00:02:21,990 Probably wrong. 58 00:02:21,990 --> 00:02:24,450 Yeah, so that looks very strange 59 00:02:24,450 --> 00:02:26,040 and that's definitely not what we expected. 60 00:02:26,040 --> 00:02:28,320 Let's, let's mess it up even more. 61 00:02:28,320 --> 00:02:33,090 So if we do that, this will definitely, oh yeah, we've, 62 00:02:33,090 --> 00:02:34,770 we've completely destroyed it. 63 00:02:34,770 --> 00:02:37,440 So let's, let's ask it. 64 00:02:37,440 --> 00:02:42,440 This is my code for displaying the Mandelbrot set. 65 00:02:44,460 --> 00:02:45,663 What is wrong with it? 66 00:02:49,920 --> 00:02:53,703 And then let's go ahead and copy that in here. 67 00:02:57,060 --> 00:02:58,140 Your code looks mostly correct, 68 00:02:58,140 --> 00:03:00,000 but there is a small issue with the formula used 69 00:03:00,000 --> 00:03:02,370 to calculate the iterative sequence for each point. 70 00:03:02,370 --> 00:03:04,110 The Mandelbrot set is defined as a set 71 00:03:04,110 --> 00:03:08,190 of complex number C versus the sequence Z times N plus 1 72 00:03:08,190 --> 00:03:12,390 is equivalent to Z of N to the power of 2 73 00:03:12,390 --> 00:03:13,740 plus C does not diverge. 74 00:03:13,740 --> 00:03:15,210 So this is basically just the math 75 00:03:15,210 --> 00:03:17,790 behind this really beautiful fractal, 76 00:03:17,790 --> 00:03:20,910 but yeah, it, it's able to point out exactly, 77 00:03:20,910 --> 00:03:22,980 so like, it's saying you've modified the formula 78 00:03:22,980 --> 00:03:24,240 to be this instead, 79 00:03:24,240 --> 00:03:27,120 which changes the nature of the set being generated. 80 00:03:27,120 --> 00:03:29,730 So if you go ahead and fix that real quick, 81 00:03:29,730 --> 00:03:31,170 it should give us the right answer again. 82 00:03:31,170 --> 00:03:33,750 And that's, that's really funny 'cause it almost 83 00:03:33,750 --> 00:03:34,950 knows exactly what we did. 84 00:03:34,950 --> 00:03:36,270 We've modified the formula. 85 00:03:36,270 --> 00:03:38,430 That's, that's a funny way of wording it. 86 00:03:38,430 --> 00:03:39,630 But yeah, we can see 87 00:03:39,630 --> 00:03:41,940 that it's once again giving us the code 88 00:03:41,940 --> 00:03:44,190 pretty much the same thing as what it gave before. 89 00:03:44,190 --> 00:03:47,280 I don't see any really big changes here, 90 00:03:47,280 --> 00:03:48,480 but yeah, we can see that, 91 00:03:48,480 --> 00:03:50,160 that the two numbers we had modified, 92 00:03:50,160 --> 00:03:52,803 this became 1.5, this became 1, I believe. 93 00:03:53,670 --> 00:03:55,470 Those, those are back to normal, right? 94 00:03:55,470 --> 00:03:57,720 And that's funny, that it's able to kind of 95 00:03:57,720 --> 00:03:59,790 just pick out on exactly what was wrong 96 00:03:59,790 --> 00:04:01,290 'cause it knew what was right.
