Brian, how you been? 00:00:20.080 --> 00:00:21.000 I am great. 00:00:21.000 --> 00:00:21.860 Nice. Me too. 00:00:21.860 --> 00:00:22.440 Cold though. 00:00:22.440 --> 00:00:26.640 Yeah. I don't know what happened. It's like winter, mid-January. I guess it's supposed to 00:00:26.640 --> 00:00:30.040 be cold. But yeah, it's cold. Maybe. My daughter said this morning, 00:00:30.040 --> 00:00:34.440 like, when are we going to get snow? And I said, well, I hope never because I don't have snow tires 00:00:34.440 --> 00:00:38.620 yet. I just bought snow tires for my car so I can drive up to the mountains and go skiing real easy. 00:00:38.620 --> 00:00:43.440 So I'm ready. It can snow whenever. But yeah, if it's not going to snow, let it be a little warm. 00:00:43.440 --> 00:00:50.140 So speaking of wintry type things, advent calendars, those are a type of things that folks use a lot 00:00:50.140 --> 00:00:51.420 in December, right? 00:00:51.420 --> 00:00:56.180 Yeah. And actually, this last December, I totally meant to do the advent of code thing, 00:00:56.320 --> 00:01:01.200 but I didn't. And also one of the things I'm doing this upcoming year is I'm trying to, 00:01:01.200 --> 00:01:07.020 I read a great article about practicing programming. I want to try to do, incorporate more practice 00:01:07.020 --> 00:01:14.140 outside of just doing my own work at work, but practicing extra things. And there's challenges 00:01:14.140 --> 00:01:19.820 and code things and little snippets and everything. But sometimes I just want like 20 minutes of reading 00:01:19.820 --> 00:01:26.640 reading something. And this is great. So I ran across this. It's from Michael Fogelman. It's the 00:01:26.640 --> 00:01:33.100 advent of code 2018 solutions. And it's pretty much he just talks through all the different, 00:01:33.100 --> 00:01:39.340 he went through all of the advent of code for 2018, and then he solved them in Python. And a lot of people 00:01:39.340 --> 00:01:44.740 have posted their solutions on GitHub. This is a nice write up that he has to describe how he solved 00:01:44.740 --> 00:01:48.000 them. And there's some nice code comments. It's really put together well. 00:01:48.000 --> 00:01:51.780 Yeah, I like it. You just sort of cruise through and see the problem, see the solution, 00:01:51.780 --> 00:01:57.700 see what you think. I find looking at other people's solutions of fairly simple programs, 00:01:58.020 --> 00:02:02.960 especially compared to your own. It's a pretty interesting experience. Like, oh yeah, 00:02:02.960 --> 00:02:07.120 I totally solved this. And then you look like, oh wait, they did that in two lines and mine took 10. 00:02:07.120 --> 00:02:10.160 Or why did they do it that way versus this? It's pretty cool. 00:02:10.160 --> 00:02:15.280 Yeah. Looking over, reading code is one of the ways to get better. So it's a good way to practice 00:02:15.280 --> 00:02:16.940 is reading other people's code. 00:02:16.940 --> 00:02:22.320 Yeah. And it's not like read the Django source code or read the request source code. And it's like a huge 00:02:22.320 --> 00:02:25.760 undertaking, right? These are 10, 2025 lines of code. 00:02:25.760 --> 00:02:30.020 Yeah. Yep. Definitely. So I dropped this in because I think I'm going to start 00:02:30.020 --> 00:02:35.420 trying to incorporate, sprinkle in some reading, reading of these in with my daily practice. 00:02:35.420 --> 00:02:39.760 Yeah. I think that's a good idea. Do you know what the most popular platform that Python runs on 00:02:39.760 --> 00:02:40.380 is, Brian? 00:02:40.380 --> 00:02:42.380 Probably Macs. Mac laptops. 00:02:42.380 --> 00:02:47.600 A lot of Mac, a lot of Mac laptops, a lot of stickers on them. That's what you'd believe if you 00:02:47.600 --> 00:02:52.640 were at a conference like PyCon or something, everyone's running around with their Apple logos glowing or 00:02:52.800 --> 00:02:57.640 sadly no longer glowing on the new Macs. But nonetheless, it feels like when you're in 00:02:57.640 --> 00:03:03.940 those environments, it's mostly Mac and some Linux and obviously server side Linux. But really, 00:03:03.940 --> 00:03:10.020 a lot of the surveys say most of the users, you know, by a pretty wide margin are actually on 00:03:10.020 --> 00:03:16.800 Windows. So we're talking students, we're talking corporate environments, a lot of folks who don't 00:03:16.800 --> 00:03:21.080 show up necessarily carrying those around at conferences, but that's where it is, right? 00:03:21.080 --> 00:03:21.320 Yeah. 00:03:21.320 --> 00:03:28.560 So the big news is that the PSF broadly and specifically Steve Dower, one of the core devs, 00:03:28.560 --> 00:03:36.800 whose works at Microsoft, has released Python 3.7 as an official app on the Windows 10 store. 00:03:36.800 --> 00:03:37.380 Nice. 00:03:37.580 --> 00:03:42.720 So there's all sorts of stuff that is really awesome from that. So that means you can just 00:03:42.720 --> 00:03:48.140 go to your Windows store and search for Python and say, yeah, I want that. You can actually already 00:03:48.140 --> 00:03:52.940 do that for like Ubuntu subsystems and stuff. So you can do that for Linux distribution, surprisingly, 00:03:52.940 --> 00:03:58.760 and run those as like subsystems in Windows, but not Python. And some of the stuff that's really cool is 00:03:58.760 --> 00:04:06.140 it automatically takes care of a couple of problems that were incompatibilities between Windows and the 00:04:06.140 --> 00:04:13.240 other operating systems. So for example, Python 3 is a command in the Windows 10 app store version, 00:04:13.240 --> 00:04:17.960 but not the one you actually install separately. So now if you see instructions like type Python 3, 00:04:17.960 --> 00:04:20.940 this, that, like that now works on Windows 2 also. 00:04:20.940 --> 00:04:21.660 That's nice. 00:04:21.660 --> 00:04:27.780 Yeah. So it's a little more similar. It automatically puts that stuff in the path. I believe the place 00:04:27.780 --> 00:04:33.300 where you pip install stuff no longer requires admin access to do it because it's under your user 00:04:33.300 --> 00:04:35.780 profile as part of the store stuff. So a whole bunch of good things. 00:04:35.780 --> 00:04:38.700 Have you talked to anybody to find out when we're going to get to the point where 00:04:38.700 --> 00:04:41.900 the default Python is going to be Python 3 anyway? 00:04:41.900 --> 00:04:46.340 That would be sweet, wouldn't it? You know, all the stuff I've seen about it is like, 00:04:46.340 --> 00:04:48.900 it would be great, but it also caused a lot of problems. 00:04:48.900 --> 00:04:49.380 Yeah. 00:04:49.380 --> 00:04:54.740 We saw that Red Hat Enterprise Linux is actually moving away from having a Python command at all. 00:04:55.040 --> 00:04:59.560 So now it's either Python 3 or Python 2 and you have to be super explicit everywhere. 00:04:59.560 --> 00:05:06.900 So I would love to see that, but I don't see it. On my systems, Python means Python 3 because I've 00:05:06.900 --> 00:05:10.540 changed the path around. So that works that way, but not everywhere, you know? 00:05:10.700 --> 00:05:15.300 Yeah. You recently talked about this and a lot of other things on Talk Python, right? 00:05:15.300 --> 00:05:22.200 Yeah. I had Steve Dower come over onto Talk Python and talk about his retrospective of Python's 00:05:22.200 --> 00:05:28.080 journey at Microsoft, which is actually really interesting. It sort of matches the open source 00:05:28.080 --> 00:05:32.820 journey from a very closed source company to way more open source. And there's a lot of cool stuff 00:05:32.820 --> 00:05:36.880 going on there. They have a ton of core developers working at Microsoft, actually. It's pretty neat. 00:05:37.040 --> 00:05:39.140 Yeah. That was a really interesting conversation. I like that. 00:05:39.140 --> 00:05:44.400 Yeah. Thanks. So there is one limitation on the Windows Store version of Python that maybe is 00:05:44.400 --> 00:05:49.400 worth throwing out there while we're talking about it is they don't have full write access to shared 00:05:49.400 --> 00:05:55.580 locations, like for example, the registry or SQL and backslash program files or stuff like that. 00:05:55.580 --> 00:06:00.840 Right. So it's kind of only has access to your user profile stuff, you know, whatever you can do 00:06:00.840 --> 00:06:06.220 without raising your permissions at UAC stuff. So that's a limitation that you may run into 00:06:06.220 --> 00:06:11.580 because the Windows Store apps are more locked down than regular apps. But still, I think this is 00:06:11.580 --> 00:06:14.900 super cool. You can go and just say, hey, you don't need to be an admin. You just go to your 00:06:14.900 --> 00:06:19.120 Windows Store, you click this little button and you also have Python 3 as a command. It's quite nice. 00:06:19.120 --> 00:06:23.880 Can you write stuff that's outside of your little environment? Not write stuff, but read it. 00:06:23.880 --> 00:06:27.200 Yeah. I'm pretty sure you can. Like you could read the registry. I would think things like that, 00:06:27.200 --> 00:06:32.020 whatever you would be able to do without that little, this program would like to use admin rights. 00:06:32.020 --> 00:06:35.320 Yes, no dialogue pop-up. I suspect you'd be able to do. Yeah. 00:06:35.400 --> 00:06:38.440 I think that's a good idea anyway. So it's going to be in the App Store. 00:06:38.440 --> 00:06:44.360 Yeah, exactly. So, you know, I would actually love to see that on macOS, right? If Python 3 was an 00:06:44.360 --> 00:06:48.780 option on macOS, because the auto-updating feature is pretty cool. Like you just wake up one day and 00:06:48.780 --> 00:06:52.020 boom, you have the next version of Python. Of course, that could cause its own problems, 00:06:52.020 --> 00:06:53.080 but it wouldn't be bad. 00:06:53.080 --> 00:06:55.760 Python 5? What's that? 00:06:55.760 --> 00:06:59.840 Oh my goodness. It's amazing and nothing works anymore. What happened? 00:06:59.840 --> 00:07:04.220 No, that's pretty cool though. I'm happy to see it getting some serious attention over there. 00:07:04.320 --> 00:07:06.040 Yeah. Definitely. All right. Well, when's next? 00:07:06.040 --> 00:07:11.760 There's a project so new that it like came in in November this last year. It's a project called 00:07:11.760 --> 00:07:12.900 Bocadio. 00:07:12.900 --> 00:07:15.340 Yeah, that's how I would say it as well. Yeah. Bocadio. 00:07:15.340 --> 00:07:16.120 Yeah. 00:07:16.120 --> 00:07:16.700 Yeah, I think so. 00:07:16.700 --> 00:07:21.180 Tagline is a modern Python web framework filled with asynchronous salsa. But the, 00:07:21.180 --> 00:07:24.360 I'm not really going to talk about that. I'm going to talk about article that the, 00:07:24.360 --> 00:07:30.440 the maintainer, it's a four month banca wrote an article called how I built a Python web framework 00:07:30.440 --> 00:07:37.280 and became an open source maintainer. And it's this really fascinating article talking about pretty 00:07:37.280 --> 00:07:41.200 much what he went through. He knew that there were a lot of other web frameworks already, 00:07:41.200 --> 00:07:46.580 but he, he built this to try to learn the internals of how to build a web framework and then just did it in 00:07:46.580 --> 00:07:51.400 the open. But there's some really great advice. One of the things he credits from somebody else 00:07:51.400 --> 00:07:57.820 called Funky Bob is reinventing the wheel is an awesome way to learn. And sometimes what you learn 00:07:57.820 --> 00:08:02.660 is just how much are your existing frameworks are doing for you. I thought that was cool. 00:08:02.660 --> 00:08:03.300 That was very cool. 00:08:03.440 --> 00:08:09.040 This thing went from like just inception to building it, to putting up docs and getting 00:08:09.040 --> 00:08:15.040 extra maintainers in like the course of a month in November. And now it's, it's still going, 00:08:15.040 --> 00:08:20.920 but there's like one of the discussions in the article is talking about how he tried to put as 00:08:20.920 --> 00:08:26.760 much in the read me as possible right off the bat, like a change log and contributing guidelines and, 00:08:26.760 --> 00:08:32.840 and how to work it and everything. But the read me got huge. So he, that migrated to 00:08:32.840 --> 00:08:40.200 a GitHub pages, static site generator doc site. And then also one of the things is, 00:08:40.200 --> 00:08:45.380 he had all of his to do items of what he wanted to work on next in a Trello doc in Trello, 00:08:45.380 --> 00:08:50.180 but nobody else can see that. So he moved, Trello issues to GitHub issues. 00:08:50.180 --> 00:08:57.960 And this process of trying to make, do a new project in a way that is open and encouraging other 00:08:57.960 --> 00:09:01.660 people to help out. And then at the end of the article, it goes through, I'm not going to go through 00:09:01.660 --> 00:09:07.080 all of these, but there's a whole bunch of tips on what to do with the project to make it encourage 00:09:07.080 --> 00:09:12.700 other people to get involved. And this is like a goldmine of information for people wanting to start 00:09:12.700 --> 00:09:13.700 an open source project. 00:09:13.700 --> 00:09:18.420 Yeah. If you're thinking about an open source project or how to make it grow, there's, you're 00:09:18.420 --> 00:09:23.580 right. There is an incredible amount of tips. I mean, there's probably 45 specific things like 00:09:23.580 --> 00:09:26.660 this helps, this helps, this helps, right? So that's, that's really awesome. 00:09:27.280 --> 00:09:32.100 Yeah. If all this information at the bottom, he could have written, written a book on this. 00:09:32.100 --> 00:09:33.780 and maybe he will, but yeah, maybe he will. 00:09:33.780 --> 00:09:36.920 But thanks, Floremund for putting this together. 00:09:36.920 --> 00:09:41.660 Yeah, it looks great. And the framework looks pretty nice as well. I like it. I feel like a lot 00:09:41.660 --> 00:09:48.820 of these web frameworks are like slight derivatives of the Flask API. They seem to all be centering 00:09:48.820 --> 00:09:52.440 around Flask for some reason, but you know, Flask is pretty good. So that's cool. 00:09:52.440 --> 00:09:52.900 Yeah. 00:09:52.900 --> 00:09:56.640 Speaking of cool, I heard Kubernetes is cool. Kelsey Hightower told us it was, 00:09:56.640 --> 00:09:59.100 and definitely showed us a cool demo at a PyCon. 00:09:59.100 --> 00:10:00.960 Yeah. I believe anything Kelsey says. 00:10:00.960 --> 00:10:07.660 Yeah, for sure. So Kubernetes is a way to basically orchestrate containers, right? Often you don't want 00:10:07.660 --> 00:10:12.300 to run one container. You want to run multiple ones, one with a database, a couple of web front ends, 00:10:12.380 --> 00:10:18.960 things like that. And it's really nice way to like do zero downtime deployment on top of that and so on. 00:10:18.960 --> 00:10:25.140 So DigitalOcean, who's sponsoring the show, of course, has just officially publicly released, 00:10:25.140 --> 00:10:31.700 no longer preview status, their DigitalOcean Kubernetes service. So it's like a managed service 00:10:31.700 --> 00:10:39.140 and you can basically sign up for it and configure a Kubernetes cluster in a couple of seconds and 00:10:39.140 --> 00:10:45.920 provision it and log in within a couple of minutes. So it's super easy to scale. You take inbound traffic 00:10:45.920 --> 00:10:51.580 and just access your data over block storage, pass it through your load balancers. It's all great. 00:10:51.580 --> 00:10:59.860 So they also say they saw a 2.4 times, not percent, times better price to performance compared to other 00:10:59.860 --> 00:11:05.340 providers. So I can definitely believe that DigitalOcean is awesome. So anyway, if you're thinking about this, 00:11:05.340 --> 00:11:12.020 check them out at pythonbytes.fm/DigitalOcean, get $100 free credit for new users and try your hand at some 00:11:12.020 --> 00:11:19.100 Kubernetes clusters. Nice. Yeah, indeed. You could even probably, you know, serve up Bocadio on Kubernetes. 00:11:19.100 --> 00:11:26.300 That'd be fun. Yeah. Cool. Well, one thing that we talked about recently, and so this is a little bit of a 00:11:26.300 --> 00:11:30.660 follow-up is the maintainability score. Do you remember what we were talking about with the 00:11:30.660 --> 00:11:34.680 maintainability score? It was like a sub idea of something that we were covering recently. 00:11:34.680 --> 00:11:37.040 I totally remember, but I don't remember the main topic. 00:11:37.040 --> 00:11:41.180 I don't. It's always so many things we cover every week. But yeah, it's one of the projects and it was 00:11:41.180 --> 00:11:45.660 like, hey, this has a maintainability score of A. And we're like, wait, where did you get that score? 00:11:45.660 --> 00:11:51.040 So a friend of the show, Anthony Shaw sent over, you know, he's done this project called Wiley. 00:11:51.040 --> 00:11:52.680 Did you guys talk about it on your show? 00:11:52.680 --> 00:11:54.220 We talked about it briefly, yeah. 00:11:54.220 --> 00:12:02.080 Yeah. So Wiley is a Python app for tracking and reporting on timing and complexity and tests and 00:12:02.080 --> 00:12:07.940 things like that. So what you can do is you can point this at your project and tell it to analyze it 00:12:07.940 --> 00:12:13.360 and then generate a bunch of reports. And it has two types of reports that are relevant to this 00:12:13.360 --> 00:12:17.560 maintainability index. It has just a number, like a percentage, and I think higher is better there. 00:12:17.680 --> 00:12:24.860 And also it has a rank from like A to F, like a grade score on it. So you can run this against 00:12:24.860 --> 00:12:29.280 your code and ask it. And then you can even graph that kind of stuff over time. So it's getting, 00:12:29.280 --> 00:12:34.440 on the reports, it'll say, ah, it's lost some maintainability or it's gained some maintainability, 00:12:34.440 --> 00:12:35.600 which I thought was pretty cool. 00:12:35.600 --> 00:12:36.540 Yeah, that is cool. 00:12:36.540 --> 00:12:37.220 Yeah. 00:12:37.220 --> 00:12:42.760 So check out Anthony's project. I'll link to it, of course, in the show notes. And if 00:12:42.760 --> 00:12:49.520 you can see how well or not well Wiley thinks your app is doing. Even has a GitHub pre-commit hook, 00:12:49.520 --> 00:12:51.240 as all the cool things do these days. 00:12:51.240 --> 00:12:55.280 Yeah. That's a fairly new project too. Wiley's only been around for a couple, 00:12:55.280 --> 00:12:56.720 two, three months or something. 00:12:56.720 --> 00:12:59.780 Yeah, absolutely. It's pretty new. Would you say it's awesome? 00:12:59.780 --> 00:13:02.360 I would say it's awesome. I think so. Yeah. 00:13:02.360 --> 00:13:03.200 What else is awesome? 00:13:03.200 --> 00:13:07.200 I kind of like the awesome lists. So awesome lists, if you're not familiar with them, 00:13:07.200 --> 00:13:12.200 are, they're usually on GitHub, but they're basically, the readme is filled with links to 00:13:12.200 --> 00:13:17.520 a whole bunch of other, other projects of a particular type. There's two awesome lists that 00:13:17.520 --> 00:13:23.920 I came across recently. One of them is awesome Python security resources. And the other one is 00:13:23.920 --> 00:13:32.220 awesome Flake 8 extensions. So as far as security resources, it covers tools and education resources. 00:13:32.220 --> 00:13:34.020 And then a couple of companies also. 00:13:34.020 --> 00:13:39.380 The very first one that it has listed here is secure.py, which we talked about just I think last week or just recently. 00:13:39.380 --> 00:13:43.540 Yeah. And we've also, I think we've talked about Bandit also for static analysis. 00:13:43.540 --> 00:13:44.080 Yeah. 00:13:44.080 --> 00:13:49.840 Some of these we've talked about. And, and then I also, I really liked that it also included some education resources. 00:13:49.840 --> 00:13:52.280 If you want to learn more about security. 00:13:52.280 --> 00:13:52.700 For sure. 00:13:52.700 --> 00:13:56.040 For your software. So this is a nice place to go for security stuff. 00:13:56.240 --> 00:14:09.580 And then I like Flake 8 anyway, as just as a tool by itself for static code analysis. But I like that it has a plugin system with it. And so there's lots of different extensions to Flake 8. 00:14:09.580 --> 00:14:15.140 So Brian, for the couple of folks out there who don't know what Flake is, Flake 8 is, give them a quick, the elevator pitch. 00:14:15.140 --> 00:14:21.580 I don't know the elevator pitch. It's not PEP 8 anymore. It's like PyCode style or something like that. 00:14:21.580 --> 00:14:26.140 Yeah. It's a format, basically the formatting conventions of the language, right? 00:14:26.140 --> 00:14:33.360 Yeah. Flake 8 itself runs the checks for those, but it, and I think the 8 is because it checks a whole bunch of other things. 00:14:33.360 --> 00:14:40.540 What it does cyclical, some complexity algorithm and gosh, you're putting me on the spot here, man. 00:14:40.540 --> 00:14:45.840 No, no, that's close enough though. But so basically it analyzes the quality of your code, right? But it only does so much. 00:14:45.840 --> 00:14:51.120 But it's definitely a static analysis. It's just looking at, looking at it just without running it. 00:14:51.120 --> 00:14:53.180 So you found a couple of plugins for it? 00:14:53.180 --> 00:14:59.360 Yeah. The extensions, there's a whole bunch of them. There's some security ones that actually overlap. 00:14:59.360 --> 00:15:06.060 The other, the security resources in the previous list, if you can run them from Flake 8. 00:15:06.060 --> 00:15:11.620 So like the static analysis that's available for security, like Bandit, I think there's a Flake 8 Bandit. 00:15:11.620 --> 00:15:19.880 There's also a couple of my favorites are, this is interesting. There's a Flake 8 pytest extension that I want to try this. 00:15:19.880 --> 00:15:25.800 It doesn't actually run your pytest. What it does is it, it checks to make sure that you've got pytest style assertions. 00:15:25.800 --> 00:15:31.760 So one of the benefits of pytest is just regular assertions and not like the unit test stuff. 00:15:31.760 --> 00:15:38.900 If you've converted from unit test to pytest, you might still have some of those other assertions laying around in this one. 00:15:38.960 --> 00:15:39.900 I'll try to get rid of those. 00:15:39.900 --> 00:15:50.780 Yeah. One that pops out to me is like Flake 8 dash docstrings, which actually checks the docstring code for you, which is pretty awesome. 00:15:50.780 --> 00:15:55.180 Validates this restructured text of your documentation. That's sweet. 00:15:55.180 --> 00:15:56.080 Oh, that's nice. Yeah. 00:15:56.080 --> 00:15:56.700 Yeah. 00:15:56.980 --> 00:15:58.440 So there's just so many in here. 00:15:58.440 --> 00:16:05.420 Yeah. And there was, I didn't write this one down. There was one that like checks for, it checks to make sure that you're not mocking things that didn't exist. 00:16:05.620 --> 00:16:12.980 So the point of mock is to fake out existing functionality so that you do something different. 00:16:12.980 --> 00:16:21.340 One of the things that you can muck up with is you can be mocking the wrong function name and it'll work just fine in your tests. 00:16:21.340 --> 00:16:22.620 Your code won't run. 00:16:23.020 --> 00:16:28.220 This plugin will check to make sure that you're mocking real existing methods and not made up methods. 00:16:28.220 --> 00:16:31.140 Yeah. Cool. Well, these are great. These are awesome finds, right? 00:16:31.140 --> 00:16:31.580 Yeah. 00:16:31.580 --> 00:16:38.000 Another thing that's awesome is logging. So remember a couple of weeks ago, we talked about Log Guru? 00:16:38.000 --> 00:16:38.800 Yeah. 00:16:38.800 --> 00:16:40.340 Log Guru? Log Guru? We don't know. 00:16:40.340 --> 00:16:40.880 Log Guru. 00:16:40.880 --> 00:16:44.280 We'll just try all the variations until one of them hits, I'm guessing. 00:16:44.280 --> 00:16:46.040 And of course, just kind of- 00:16:46.040 --> 00:16:47.080 I think it rhymes with kangaroo. 00:16:47.080 --> 00:16:52.660 It does. And so just like when we talked about GUI frameworks, we're like, oh, 00:16:52.660 --> 00:16:55.600 here's like a couple of them. And just people are like, oh, and did you know? Did you know? 00:16:55.600 --> 00:17:00.840 So here's another really cool logging framework that Robert Young sent over to us to say, oh, 00:17:00.840 --> 00:17:03.200 you talked about Log Guru. You should definitely check this out. 00:17:03.200 --> 00:17:05.660 So this is called Fast Logging. 00:17:05.660 --> 00:17:11.720 So Fast Logging is a replacement for the standard logging module, and it's mostly compatible, 00:17:11.720 --> 00:17:15.860 which is pretty cool. But would you guess from the name that it's faster? 00:17:15.860 --> 00:17:16.900 I should hope so. 00:17:16.900 --> 00:17:21.920 So basically the point is logging can be kind of slow, it turns out, in the standard logging module. 00:17:22.300 --> 00:17:28.320 But this one is faster. And not just like 20% faster, it's like five times faster for a regular 00:17:28.320 --> 00:17:32.300 file. And if you're doing rotating log files, it's actually about 13 times faster. 00:17:32.300 --> 00:17:36.420 So if you're doing a lot of logging and it's turning, basically the logging is slowing down 00:17:36.420 --> 00:17:38.020 your app, think about fast logging. 00:17:38.020 --> 00:17:39.120 Yeah. Nice. 00:17:39.280 --> 00:17:45.120 Yeah. And it has a bunch of cool features. So like if you install Colorama, which is a great 00:17:45.120 --> 00:17:51.240 color way to do output on the console, it'll actually do colored logging when it's logging 00:17:51.240 --> 00:17:57.360 to print, you know, standard out. You can set the maximum file size and rotating a lot of 00:17:57.360 --> 00:18:03.420 options on the rotating stuff. It'll also like Log Guru compress the older file, older log 00:18:03.420 --> 00:18:08.220 files, which can be 10x or more savings. Like those log files compress really, really well. 00:18:08.220 --> 00:18:13.860 You can do like only log every so often based on domains, different files, like all sorts of 00:18:13.860 --> 00:18:19.280 stuff. You get callbacks. One thing that's kind of cool is it'll do logging on background threads 00:18:19.280 --> 00:18:24.380 per file, which is pretty cool if you configure it. So if you're like, I want to log this stuff, 00:18:24.440 --> 00:18:29.920 but I know that might slow down my app and I don't want any slowdown. So this will basically 00:18:29.920 --> 00:18:34.880 push it off to a background thread, which will eventually pick it up and write it. So you can 00:18:34.880 --> 00:18:39.220 get, keep stuff flowing right along, maybe in a web request or something like that. It's pretty cool. 00:18:39.220 --> 00:18:40.640 Yeah. Yeah. Very nice. 00:18:40.640 --> 00:18:42.900 Yeah. So thanks Robert for sending that in. That's a good one. 00:18:42.900 --> 00:18:46.080 Brian, that's it for our official items. Got anything else? 00:18:46.080 --> 00:18:46.880 I actually don't. 00:18:46.880 --> 00:18:48.960 Nope. All right. Right on. 00:18:48.960 --> 00:18:49.380 How about you? 00:18:49.380 --> 00:18:53.960 Well, I have two things that I'd like to just throw out there really quick. First of all, 00:18:53.960 --> 00:19:00.840 I'm doing a live webcast, but also be recorded over on January 24th at 11 AM Pacific time, 00:19:00.840 --> 00:19:07.420 basically working and showing async and await in Python and building a little app that uses that. 00:19:07.420 --> 00:19:11.980 So if you got a free hour and you want to drop in, check that out, put the links in the show notes 00:19:11.980 --> 00:19:19.340 there. And we already talked about Anthony Shaw and his Wiley, but he also sent over a heads up, 00:19:19.340 --> 00:19:27.060 which I also got from GitHub to watch your YAML. YAML apparently had some pretty decent security 00:19:27.060 --> 00:19:31.840 vulnerability. Like, I don't know how many people know, but you can actually just straight up execute 00:19:31.840 --> 00:19:38.640 arbitrary Python code in a YAML file. That's bad, right? So like, yeah. So, Hey, upload your 00:19:38.640 --> 00:19:42.240 configuration file and we'll just run it for you. And like the configuration file is like, 00:19:42.760 --> 00:19:50.180 username is this password is that database format is this bang Python format, the system or do other 00:19:50.180 --> 00:19:56.800 bad things. Right? Like it was really crazy that the YAML format just lets you embed code into what 00:19:56.800 --> 00:20:01.340 is otherwise supposed to be a static file. All right. So the warning is that you're supposed to use, 00:20:01.340 --> 00:20:07.300 what's it called? Safe underscore load instead of load, but they've fixed some stuff to make that 00:20:07.300 --> 00:20:11.900 basically make that more obvious. And with a new version of PyYAML. So if you're using PyYAML, 00:20:11.900 --> 00:20:17.160 GitHub will give you a warning about this. Anyway, it seems like it could actually have a lot of 00:20:17.160 --> 00:20:21.700 consequences if you don't update that. So check that out. Yeah. But also if you're using PyYAML, 00:20:21.700 --> 00:20:27.140 updating to the newest version should fix that, right? Yes, you should. But what's weird is we talked 00:20:27.140 --> 00:20:33.840 about zero for the way you fix the PyYAML problem is you take a, an official, like, I'm just messing with it, 00:20:33.840 --> 00:20:39.980 like 1.3 release and you upgrade it to a beta release. So it's like, so you have to install 00:20:39.980 --> 00:20:44.200 the beta version to not have the security problem, which I don't know, take that for what it is. 00:20:44.200 --> 00:20:49.400 Yeah. Okay. Come on, PyYAML people. That's right. All right. Do you have a joke for us this week? 00:20:49.400 --> 00:20:55.000 I don't. All right. I have a joke. This is an oldie, but a goodie. It's about Python, 00:20:55.000 --> 00:21:00.860 which is pretty sweet. So if you're out there and you type Python on your terminal command prompt, 00:21:00.860 --> 00:21:05.880 and then you just import anti-gravity, like the command, right? Import anti-gravity. 00:21:05.880 --> 00:21:10.940 It turns out, have you done this, Brian, before? Yeah, but it's good to bring it up because some 00:21:10.940 --> 00:21:14.360 people don't know about it. Yeah, exactly. This is one of the better things built into the Python 00:21:14.360 --> 00:21:21.080 repo, honestly. And so what it does is it actually opens up an XKCD comic, which is a great joke 00:21:21.080 --> 00:21:27.660 about Python's packages and libraries. So there's a picture, there's a stick figure flying up in the air 00:21:27.660 --> 00:21:34.240 and the stick figure on the ground, obviously amazement on his blank face, stick face says, 00:21:34.240 --> 00:21:40.100 how are you flying? Python. I just learned it last night. Everything's so simple. Hello world is 00:21:40.100 --> 00:21:45.260 just print. Hello world. The guy on the ground says, I don't know. Dynamic typing, white space. 00:21:45.260 --> 00:21:49.900 Guy in the air says, come on, join us. Programming is fun again. It's a whole new world up here, 00:21:49.900 --> 00:21:55.800 but how are you flying? I just typed import anti-gravity. That's it. I also sampled everything 00:21:55.800 --> 00:22:01.180 in the medicine cabinet for comparison, but I think it's the Python. It's a good, it's a little bit 00:22:01.180 --> 00:22:05.740 of goody, right? Yeah. Yeah. And while you're playing on the command line, it's not a joke, 00:22:05.740 --> 00:22:12.660 but import this. It's another hidden Easter egg, not very hidden, but that it'll show you the Zen of 00:22:12.660 --> 00:22:16.800 Python. Yep. That's awesome. I'm going to save another import joke that you can do on the terminal 00:22:16.800 --> 00:22:22.260 or in the REPL for next time or time after. Okay. But yeah, it's, I really love it that 00:22:22.260 --> 00:22:27.440 these kinds of jokes and humorous things are built in there. It's not like Python has been sterilized of 00:22:27.440 --> 00:22:34.820 all humanity. Yeah. And anti-gravity connects Python with XKCD, which is kind of neat. And one of the 00:22:34.820 --> 00:22:40.520 things I like, I can't remember where to get these, but one of the things I like about XKCD is they often 00:22:40.520 --> 00:22:45.420 talk about things that you might not know about. There's another place that I can't remember where 00:22:45.420 --> 00:22:51.060 it discusses like why it's funny. So you can read about things you don't know about. Yeah, absolutely. 00:22:51.060 --> 00:22:56.340 Absolutely. Well, thanks for recording this week. You bet. It's always fun and I always learn something. 00:22:56.340 --> 00:23:00.880 So thanks a bunch. Bye. Thank you for listening to Python Bytes.
