WEBVTT 00:00:00.001 --> 00:00:05.220 Hello and welcome to Python Bytes, where we deliver Python news and headlines directly to earbuds. 00:00:05.220 --> 00:00:11.260 This is episode 352, recorded September 12th, 2023. I'm Michael Kennedy. 00:00:11.260 --> 00:00:12.380 And I'm Brian Okken. 00:00:12.380 --> 00:00:20.680 And this episode is sponsored by us, supported by us. Support the podcast by choosing our courses, 00:00:20.680 --> 00:00:25.620 listening to our podcasts, including the new one by Brian, Python People, 00:00:25.800 --> 00:00:31.240 and the Patreon supporters, and find us on fosstodon.org. Brian, me, and the show. 00:00:31.240 --> 00:00:37.020 The link's in the show notes. And also, the show notes have how to attend the live session, if you want. 00:00:37.020 --> 00:00:37.580 Yes. 00:00:37.580 --> 00:00:39.700 Brian, what do you got to start our day here? 00:00:39.700 --> 00:00:44.900 I feel like it's the start of school, so I feel like a helicopter parent. 00:00:44.900 --> 00:00:50.000 That's right. You got your homework done? Was anyone mean to you? Can I help you out, sweetie? 00:00:51.320 --> 00:01:01.400 So, the first topic is called Heliclockter. And it is, like, apparently, it's a pun on helicopter parenting, maybe? I don't know. 00:01:01.400 --> 00:01:07.060 So, like, helicopter, but clock, get it? Kind of a helicopter. 00:01:07.760 --> 00:01:18.960 So, this was submitted by Peter Nielsen. I think he was involved in this, but the idea is, it's like date times, but they're a little bit better. 00:01:18.960 --> 00:01:25.540 So, apparently, one of the frustrations that this group had was with normal date times, and they looked into other things, 00:01:25.860 --> 00:01:35.280 is being able to just have a date time where you can just enter, like, the time, but have it be, like, aware of what time zone it's in. 00:01:35.280 --> 00:01:41.980 So, the big thing about this is a subclass of date time with some extra features. 00:01:41.980 --> 00:01:47.900 So, you've got a date time TZ, which is a time zone aware date time. 00:01:48.040 --> 00:01:53.600 And then you've got a local one, which ensures that the time zone is local time, and then a UTC. 00:01:53.600 --> 00:02:02.800 So, there are some other solutions out there that deal with just assume UTC plus zero, but that's often not convenient. 00:02:02.800 --> 00:02:08.920 And I guess one of the things they had was they wanted to be able to have date time items as objects, 00:02:08.920 --> 00:02:14.500 and then be able to sort them, but have them keep, like, maintain what time zone they were created in and stuff, 00:02:14.500 --> 00:02:16.980 which is kind of an interesting thing. 00:02:16.980 --> 00:02:21.600 So, they've got, it looks just like working with time zones. 00:02:21.600 --> 00:02:25.400 So, it looks pretty easy to work with if you've ever worked with time zones. 00:02:25.400 --> 00:02:32.320 They do have some other cool features, like statically type checkable and Pydantic integration, which is kind of neat. 00:02:32.320 --> 00:02:38.920 Anyway, they've got also an article about why they created it. 00:02:38.920 --> 00:02:41.200 Time flies when you're having zones. 00:02:41.200 --> 00:02:41.800 Nice. 00:02:41.800 --> 00:02:51.740 So, it's a pretty interesting discussion going through why they chose the solution they did of creating their own and everything. 00:02:51.740 --> 00:02:54.860 And being able to use it with mypy also is kind of cool. 00:02:54.860 --> 00:02:55.640 So, yeah. 00:02:55.640 --> 00:02:56.000 Yeah. 00:02:56.000 --> 00:02:57.000 Neat time zone. 00:02:57.000 --> 00:03:00.100 Shout out to Arrow and Pendulum as well, or some of the other well-known ones. 00:03:00.100 --> 00:03:00.300 Yeah. 00:03:00.300 --> 00:03:00.780 Yeah. 00:03:00.780 --> 00:03:06.100 Even a Datetime UTC they found, but it's UTC zero. 00:03:06.100 --> 00:03:09.720 And then they even talked about why that, like, how they designed it and why. 00:03:09.720 --> 00:03:16.380 So, their first thing was just create a completely new type, but then they, you know, came up with some problems with that. 00:03:16.380 --> 00:03:18.480 So, they came up with subclassing. 00:03:18.480 --> 00:03:23.300 So, then these new types are types of Datetime also. 00:03:23.300 --> 00:03:25.100 So, you can use other things to go with them. 00:03:25.100 --> 00:03:26.540 So, I think that's a cool solution. 00:03:26.540 --> 00:03:31.900 I'm not usually a fan of subclassing, but I think the subclassing in this case makes a lot of sense. 00:03:32.580 --> 00:03:35.000 Anyway, what you got for us? 00:03:35.000 --> 00:03:35.460 Yeah. 00:03:35.460 --> 00:03:36.300 That looks good. 00:03:36.300 --> 00:03:41.100 You know, I think it sounds so easy to be working with time, but it's always so tricky. 00:03:41.100 --> 00:03:42.080 Yeah. 00:03:42.140 --> 00:03:47.860 I have something keeping with the same color scheme here, a new release for Wagtail. 00:03:47.860 --> 00:03:50.460 And I don't believe we've talked about Wagtail before. 00:03:50.460 --> 00:03:51.800 It's possible. 00:03:51.800 --> 00:03:59.300 I, I did get a chance to use our search today, you know, and just reminded how nicely that goes. 00:03:59.300 --> 00:04:01.480 I guess we've talked to at least mention it somewhere. 00:04:01.480 --> 00:04:11.940 But Wagtail is, a CNS, the CMS, the leading open source Python CMS built on Django, but you don't necessarily have to know Django. 00:04:11.940 --> 00:04:20.660 It's kind of like WordPress in the sense that you could just go through the setup steps and run WordPress and not even worry about the fact it's written in PHP. 00:04:20.660 --> 00:04:26.340 So Wagtail is a little bit like that, but just pip install Wagtail to go get going. 00:04:26.340 --> 00:04:27.700 And it's got some really cool features. 00:04:27.780 --> 00:04:33.940 I haven't really explored it too much, but it's got this really cool visual designer for people to build out web pages and stuff. 00:04:33.940 --> 00:04:34.720 Isn't that cool? 00:04:34.720 --> 00:04:38.760 So you can like hit a little plus and you get like a nice WYSIWYG. 00:04:38.760 --> 00:04:44.300 I'm going to insert a heading or insert a table or, like a image gallery with these images. 00:04:44.300 --> 00:04:47.940 It has a cool tree structure so you can organize your content. 00:04:47.940 --> 00:04:53.280 And because it's a Django, you can extend it doing Django things, which is pretty sweet. 00:04:53.280 --> 00:04:57.120 And it has a bunch of, you can make little snippets that you can use inside your pages. 00:04:57.520 --> 00:04:58.700 So that's pretty neat. 00:04:58.700 --> 00:05:01.540 And it even has a library for managing your images. 00:05:01.540 --> 00:05:02.920 So pretty cool stuff. 00:05:02.920 --> 00:05:07.780 And the news item today is an article by Megan Voss. 00:05:07.780 --> 00:05:10.460 Come over to the dark side with Wagtail five. 00:05:10.460 --> 00:05:15.900 So Wagtail 5.0 is a new release here with a bunch of cool things. 00:05:16.120 --> 00:05:22.700 So dark mode, if you want your website, which is backed by Wagtail to have dark mode, well, dark mode is a thing. 00:05:22.700 --> 00:05:23.620 It's pretty excellent. 00:05:23.620 --> 00:05:25.460 I'm a big fan of dark mode. 00:05:25.460 --> 00:05:30.040 It has SVG image support in addition for scalable vector graphics. 00:05:30.040 --> 00:05:32.020 In addition to just JPEGs and stuff. 00:05:32.020 --> 00:05:35.600 It has an accessibility and enhanced accessibility checker. 00:05:35.600 --> 00:05:36.240 That's pretty cool. 00:05:36.240 --> 00:05:42.040 Like if you're creating content and it's hard for people who have to use screen readers or something, it can tell you that you're not doing that. 00:05:42.040 --> 00:05:50.300 Like missing paragraphs as headings, misusing paragraphs as headings, use proper tags, incorrect heading hierarchy, avoid skipping levels. 00:05:50.300 --> 00:05:50.960 Oh, wow. 00:05:50.960 --> 00:05:52.240 And, you know, things like that. 00:05:52.240 --> 00:05:52.440 Right. 00:05:52.740 --> 00:05:55.020 Which is certainly my handwritten stuff. 00:05:55.020 --> 00:05:57.980 That's only, you know, if I remember that that's how it's supposed to go. 00:05:57.980 --> 00:05:58.220 Right. 00:05:58.220 --> 00:05:59.440 So pretty sweet. 00:05:59.440 --> 00:06:01.740 What's wrong with five H1s on one page? 00:06:01.740 --> 00:06:02.880 I know. 00:06:02.880 --> 00:06:03.120 I know. 00:06:03.120 --> 00:06:05.400 I really, I really have a lot to say here. 00:06:05.400 --> 00:06:06.680 So it's all H1s. 00:06:06.680 --> 00:06:16.780 It also has, what is the, when you, if you want to delete, like say you have an image or something and it's in your gallery and you're like, ah, I'm not going to use this after I'll hit delete. 00:06:16.780 --> 00:06:25.340 It keeps track of if it's used in any other pages so you don't accidentally delete something that's being used in some part of the site you didn't know about that someone else created. 00:06:25.340 --> 00:06:26.460 That's pretty awesome. 00:06:26.460 --> 00:06:37.040 More snippets, more validation, and they threw away a bunch of old code so they can work better, which, you know, may even have a blog post on addressing technical debt. 00:06:37.040 --> 00:06:40.400 But so a few breaking changes, not too many, but, you know, check it out. 00:06:40.400 --> 00:06:42.040 Anyway, Wagtail looks pretty awesome, right? 00:06:42.040 --> 00:06:47.400 I think I may have talked about it a long time ago, but anyway, not the 5.0 release because that's quite recent. 00:06:47.400 --> 00:06:47.900 Yeah. 00:06:47.900 --> 00:06:50.580 I think it's pretty cool that that's there. 00:06:50.580 --> 00:06:55.480 And I do have plans to play with it at some point, but I've had plans to play with it for a while. 00:06:55.480 --> 00:06:56.660 So anyway. 00:06:56.660 --> 00:06:57.000 Indeed. 00:06:57.000 --> 00:07:02.900 Kim out in the audience says, I know several one-person technical businesses that really like Wagtail for their sites. 00:07:02.900 --> 00:07:07.340 Easy to use for technical competent users, but doesn't require much of their time to maintain. 00:07:07.340 --> 00:07:08.100 Yeah, that seems great. 00:07:08.100 --> 00:07:08.660 Yeah. 00:07:08.660 --> 00:07:09.200 Nice. 00:07:09.200 --> 00:07:10.660 Over to you. 00:07:10.660 --> 00:07:17.160 Well, I guess I go away from Python a little bit, but we use it all the time. 00:07:17.160 --> 00:07:19.500 So I want to talk about Git. 00:07:19.500 --> 00:07:26.880 So I don't think I use any other revision control systems anymore other than Git. 00:07:26.880 --> 00:07:27.580 No CVS? 00:07:27.580 --> 00:07:28.580 No. 00:07:28.580 --> 00:07:29.460 No CVS? 00:07:29.460 --> 00:07:30.180 Any of that good stuff? 00:07:30.180 --> 00:07:31.700 Of course. 00:07:31.700 --> 00:07:32.320 Subversion. 00:07:32.320 --> 00:07:35.900 Actually, I touch on subversion once in a while. 00:07:35.900 --> 00:07:38.700 I still have kind of good feelings towards subversion. 00:07:38.700 --> 00:07:40.880 The other ones make me a little queasy. 00:07:40.880 --> 00:07:41.700 Anyway. 00:07:41.700 --> 00:07:50.500 The thing that I often want to know is just like the stuff that happened recently on a file or something or just on a Git repository. 00:07:50.500 --> 00:07:51.320 RCS. 00:07:51.320 --> 00:07:52.100 Mike Felder. 00:07:52.100 --> 00:07:52.860 Oh, field. 00:07:52.860 --> 00:07:53.420 Fiedler. 00:07:53.420 --> 00:07:53.860 Sorry. 00:07:53.860 --> 00:07:55.000 Nice. 00:07:55.000 --> 00:07:55.900 RCS. 00:07:55.900 --> 00:07:56.300 Wow. 00:07:57.140 --> 00:07:58.080 Takes me back. 00:07:58.080 --> 00:08:01.980 But so one of the things is to Git log. 00:08:01.980 --> 00:08:04.120 So looking at what's happened recently. 00:08:04.120 --> 00:08:08.460 But the Git log output is not something I like to do. 00:08:08.460 --> 00:08:18.620 Actually, using Git log is one of the reasons why I often pop up like a visual tool to look at my Git repository because it's gross. 00:08:18.920 --> 00:08:24.140 But I forgot and I knew that you could customize it, but I kind of forgot how to. 00:08:24.140 --> 00:08:25.440 So I haven't been. 00:08:25.440 --> 00:08:28.240 But this now I have because of this article. 00:08:28.240 --> 00:08:31.760 So there's an article called Git log customization from Justin Joyce. 00:08:32.300 --> 00:08:35.560 And so the default is something like that, which we're showing. 00:08:35.560 --> 00:08:42.540 It's got a really long hash number and a bunch of information, but it's hard to find the information you need. 00:08:42.540 --> 00:08:51.000 One of the things that Justin points out is that you can do just something really easy by passing in one line. 00:08:51.400 --> 00:08:59.920 Just the flag, like two dashes in one line, all one word, will make it pretty nice, actually. 00:08:59.920 --> 00:09:04.900 It just does a short hash and you can kind of see what's going on a little bit better. 00:09:04.900 --> 00:09:06.740 But it goes a lot further. 00:09:06.740 --> 00:09:09.560 And I'm going to hop down to this really cool customization. 00:09:09.560 --> 00:09:12.480 One of the things is using graph. 00:09:12.480 --> 00:09:13.960 Graph is great. 00:09:13.960 --> 00:09:19.740 --graph so that you can see kind of it does like kind of a visual representation of the different. 00:09:19.740 --> 00:09:21.800 What are those? 00:09:21.800 --> 00:09:23.980 The branches and the merges. 00:09:23.980 --> 00:09:25.080 That's it. 00:09:25.080 --> 00:09:27.080 I always forget branches and branch or fork. 00:09:27.080 --> 00:09:29.220 No, it's an ASCII art for the win there. 00:09:29.220 --> 00:09:30.700 Yeah, ASCII art. 00:09:30.700 --> 00:09:32.720 But then you can do like color and stuff. 00:09:32.720 --> 00:09:39.260 So there's the graph does color also if you have that on everything. 00:09:39.560 --> 00:09:51.020 It talks about how he also talks about how the one line is actually a like a combination of pretty one line and abbreviate commit, which is kind of cool. 00:09:51.020 --> 00:10:01.100 And then what I really love is this the thing that he like comes up with at the end so that I didn't know that you could put aliases in the get config file. 00:10:01.100 --> 00:10:04.380 So or at least I did once and I forgot about it. 00:10:04.380 --> 00:10:06.940 But this is a pretty cool long alias. 00:10:06.940 --> 00:10:09.280 He's got LG instead of log. 00:10:09.280 --> 00:10:11.920 So save a character of typing right there. 00:10:11.920 --> 00:10:13.840 But it defaults to. 00:10:13.840 --> 00:10:17.960 So it's an alias for log with a graph with 10. 00:10:17.960 --> 00:10:19.860 So default to the last 10 commits. 00:10:19.860 --> 00:10:24.580 And then this long format thing that is kind of ugly to look at. 00:10:24.660 --> 00:10:31.480 But what you get is he talks about what it all is, but what you get is the brand, the graph. 00:10:31.480 --> 00:10:36.140 But you also get somebody's name highlighted of who did it. 00:10:36.140 --> 00:10:38.100 And then also how long ago. 00:10:38.100 --> 00:10:42.680 So was it 19 hours ago or 24 hours ago or two days, three days? 00:10:42.680 --> 00:10:44.120 Really cool. 00:10:44.120 --> 00:10:47.500 Exactly what I need usually when I'm looking at a get log. 00:10:47.500 --> 00:10:48.480 So I love it. 00:10:48.480 --> 00:10:51.360 This actually inspires me to maybe play with this as well. 00:10:51.700 --> 00:10:53.220 I usually use Sourcetree. 00:10:53.220 --> 00:10:54.460 I really like Sourcetree. 00:10:54.460 --> 00:10:58.360 But, you know, sometimes you're already in the terminal and just, you know. 00:10:58.360 --> 00:10:58.900 Yeah. 00:10:58.900 --> 00:11:04.700 And so all I did, what I did is I just like opened up my home directory, get config and added this alias. 00:11:04.700 --> 00:11:06.460 And now I just use get LG. 00:11:06.460 --> 00:11:09.660 That's and then I can forget all of this. 00:11:09.660 --> 00:11:15.760 The other one of the neat things I'm like, well, if it says by default, you can put the default, whatever you want for this alias. 00:11:15.760 --> 00:11:17.100 But like 10 lines. 00:11:17.100 --> 00:11:19.380 What if I want to see like 20 lines or 30 lines? 00:11:19.720 --> 00:11:28.400 Well, if you say get LG, even though it has the dash 10 built into it and pass in like a dash 20 or dash 30, the second one overrides it. 00:11:28.400 --> 00:11:30.560 So that's clever. 00:11:30.560 --> 00:11:31.400 Works just fine. 00:11:31.400 --> 00:11:32.260 So nice. 00:11:32.260 --> 00:11:36.340 So thank you, Justin Joyce, for writing this up. 00:11:36.340 --> 00:11:38.060 Nice job, Justin. 00:11:38.060 --> 00:11:38.800 That's pretty awesome. 00:11:38.800 --> 00:11:39.460 All right. 00:11:39.460 --> 00:11:44.160 I saw that David Lord was the one listed there in the example. 00:11:44.160 --> 00:11:44.760 Yeah. 00:11:45.020 --> 00:11:51.580 Let's keep, let's keep going that theme over to historically from the flask side of things. 00:11:51.580 --> 00:11:53.440 So I want to talk about flask. 00:11:53.440 --> 00:11:55.040 I want to talk about Jinja. 00:11:55.200 --> 00:12:01.320 So Jinja is the template language that is the default for so many frameworks. 00:12:01.320 --> 00:12:02.580 It's not best. 00:12:02.580 --> 00:12:04.460 I don't think come on chameleon. 00:12:04.460 --> 00:12:05.720 So much better. 00:12:06.160 --> 00:12:09.580 But it doesn't matter if everyone's using Jinja. 00:12:09.580 --> 00:12:10.820 Like that's what people are using. 00:12:10.820 --> 00:12:11.080 Right. 00:12:11.080 --> 00:12:12.920 It's built into all the frameworks. 00:12:12.920 --> 00:12:16.980 You got to jump through hoops to like use chameleon with say FastAPI. 00:12:16.980 --> 00:12:17.440 Right. 00:12:17.440 --> 00:12:19.120 Like I created a library to do that kind of stuff. 00:12:19.220 --> 00:12:25.100 But this is about Jinja and its origins come from flask originally created by Armin Roeneker. 00:12:25.100 --> 00:12:29.600 No longer the maintainer, David Lord and folks over at pallets is. 00:12:29.600 --> 00:12:34.960 But this new project I want to give a shout out to does come from Armin and it's called mini 00:12:34.960 --> 00:12:35.660 Jinja. 00:12:35.660 --> 00:12:38.200 Like Jinja, but smaller. 00:12:38.200 --> 00:12:44.240 So mini Jinja is a powerful, but minimal dependency template engine for rust. 00:12:44.240 --> 00:12:46.320 That's compatible with Jinja and Jinja2. 00:12:46.320 --> 00:12:50.880 So if you've got a rust project and you want to have those templates, you could use this 00:12:50.880 --> 00:12:52.100 and you'd be like, okay, Michael. 00:12:52.100 --> 00:12:53.580 Well, a Python podcast. 00:12:53.580 --> 00:12:56.720 So yeah, rust is popular, but it's comparable. 00:12:56.720 --> 00:13:02.800 If you've got a Python app, it is basically not a hundred percent identical, but pretty similar. 00:13:02.800 --> 00:13:03.180 Right. 00:13:03.180 --> 00:13:09.560 The other thing though, that's kind of interesting is it does works with Python through as project 00:13:09.560 --> 00:13:12.640 called mini Jinja dash pie. 00:13:12.640 --> 00:13:19.820 And that allows you to use the rust runtime backed template engine on whatever thing it 00:13:19.820 --> 00:13:20.740 is that you're working with. 00:13:20.740 --> 00:13:21.220 Right. 00:13:21.220 --> 00:13:23.100 Flask FastAPI, whatever. 00:13:23.100 --> 00:13:23.680 Right. 00:13:23.680 --> 00:13:29.580 So you might want to use this instead when the full set of Jinja2 features is not required 00:13:29.580 --> 00:13:32.540 and you want to have the same experience across Python or rust. 00:13:32.540 --> 00:13:37.760 There's places where you can get a slightly better performance sometimes than Jinja. 00:13:37.980 --> 00:13:43.020 It was created using maturing in py03, which is pretty cool. 00:13:43.020 --> 00:13:45.160 Like the rust Python bindings. 00:13:45.160 --> 00:13:48.140 And yeah, it just shows you how to set up and whatnot. 00:13:48.140 --> 00:13:54.020 So if you're out there doing the web things, you know, maybe have a quick look at mini Jinja. 00:13:54.020 --> 00:13:55.940 If somehow that's relevant to you. 00:13:55.940 --> 00:13:58.360 Continuing the rustification of Python. 00:13:58.940 --> 00:13:59.340 Indeed. 00:13:59.340 --> 00:14:02.140 You know, it's been around for a long time, over 30 years. 00:14:02.140 --> 00:14:04.080 So surely some rust is starting to develop. 00:14:04.080 --> 00:14:07.620 I wouldn't have expected to come on so quickly all at once like that. 00:14:07.620 --> 00:14:08.360 But there you go. 00:14:08.360 --> 00:14:09.300 Yeah. 00:14:09.300 --> 00:14:09.940 Nice. 00:14:09.940 --> 00:14:12.560 That's it for all of our items, I would say. 00:14:12.560 --> 00:14:13.220 Okay. 00:14:13.340 --> 00:14:16.700 And I've got some extras, but I know you do too. 00:14:16.700 --> 00:14:17.540 So maybe you go first. 00:14:17.540 --> 00:14:18.080 Okay. 00:14:18.080 --> 00:14:20.520 Well, I was up. 00:14:20.520 --> 00:14:27.120 We were just talking at the beginning of this before we went on air that I was having some audio trouble last night. 00:14:27.120 --> 00:14:32.120 But I was getting the pytest Primary Power course ready and launched last night. 00:14:32.120 --> 00:14:38.300 So chapter six, got done recording that yesterday morning and in the evening, finished editing the audio. 00:14:38.300 --> 00:14:43.220 So the first course in a series, pytest Primary Power. 00:14:43.220 --> 00:14:44.900 And so what does it cover? 00:14:44.900 --> 00:14:49.440 It covers test functions, fixtures, built-in fixtures, parameterization, markers. 00:14:49.440 --> 00:14:55.600 And it's really the set of things I think that you have to know to be able to be using pytest effectively. 00:14:55.600 --> 00:14:59.060 You could just take this first course and I think run with it for quite a long time. 00:14:59.060 --> 00:15:02.300 So to celebrate getting it done and back to school. 00:15:02.300 --> 00:15:04.440 I know everybody's with kids. 00:15:04.440 --> 00:15:07.500 Kids are probably started last week or the week before. 00:15:07.500 --> 00:15:11.720 It might sound like it's for school, but now the kids are out of the house. 00:15:11.720 --> 00:15:14.640 You actually have time and energy to study things again. 00:15:14.640 --> 00:15:15.720 That's my house anyway. 00:15:15.720 --> 00:15:16.280 Yeah. 00:15:16.280 --> 00:15:16.860 Yeah. 00:15:16.860 --> 00:15:19.460 So I'm offering a deal for it. 00:15:19.460 --> 00:15:21.980 So 49 bucks for the first course. 00:15:21.980 --> 00:15:24.560 And if you want to do the bundle, $99. 00:15:24.560 --> 00:15:29.920 And the bundle is kind of fun because I've already had some, we've got a lot of channels to get feedback. 00:15:29.920 --> 00:15:37.540 I had some feedback this last night and this morning saying, hey, I'm trying this on Python 3.8 and it's, it doesn't work. 00:15:37.540 --> 00:15:38.820 So, but it does now. 00:15:38.820 --> 00:15:50.620 So this morning I did the, it was like the from future import annotations I had to do to make the annotations from 3.10 be compatible to Python, way back to Python 3.7. 00:15:50.620 --> 00:15:52.660 So I tested it on 3.7 this morning. 00:15:52.800 --> 00:15:54.380 So everything should be working. 00:15:54.380 --> 00:15:56.940 So anyway, pretty excited about that. 00:15:56.940 --> 00:15:57.100 Excellent. 00:15:57.100 --> 00:15:57.720 Yeah. 00:15:57.720 --> 00:15:58.200 Congratulations. 00:15:58.200 --> 00:15:59.060 That's a big step. 00:15:59.060 --> 00:16:01.420 If you see something like this, you're in the right place. 00:16:01.420 --> 00:16:02.260 So thanks. 00:16:02.260 --> 00:16:04.180 How about you? 00:16:04.180 --> 00:16:07.440 The testing code logo and roll in the course for 49 bucks. 00:16:07.440 --> 00:16:07.740 Awesome. 00:16:08.400 --> 00:16:10.340 Keeping with the course theme a little bit. 00:16:10.340 --> 00:16:14.600 I have three new courses coming out at Talk Python Training. 00:16:14.600 --> 00:16:19.600 We have a new HTMX plus Django course, which is going to be excellent. 00:16:19.600 --> 00:16:23.620 A new language based course without more detail on that. 00:16:23.620 --> 00:16:27.840 And one or two data science courses coming in quite soon. 00:16:27.840 --> 00:16:33.120 And since it's a bunch of, a bunch of things, all of them not quite released yet. 00:16:33.120 --> 00:16:38.060 Just point people at Talk Python training.talkpython.fm/getnotified. 00:16:38.060 --> 00:16:43.960 And there, if you're not already in the mailing list, put your name and email in here and you'll 00:16:43.960 --> 00:16:46.300 get to hear about them when, or keep listening to the podcast. 00:16:46.300 --> 00:16:47.760 I'm sure I'll talk about it then as well. 00:16:47.760 --> 00:16:50.980 I also just want to give a shout out to Cloudflare Turnstile. 00:16:50.980 --> 00:16:58.320 I've been going through and classifying trucks, cars, crosswalks, stoplights. 00:16:58.320 --> 00:16:59.500 Holy moly. 00:16:59.500 --> 00:17:02.740 What a dreadful, unnecessary thing. 00:17:02.740 --> 00:17:12.260 So way back in 304 on October, 2022, I talked about Turnstile, which is a privacy friendly, 00:17:12.260 --> 00:17:18.420 user friendly, privacy preserving alternative to reCAPTCHA and all those things. 00:17:18.420 --> 00:17:20.000 And it just sits down here. 00:17:20.000 --> 00:17:23.980 And while we're waiting, you know how, like sometimes if you are slow filling out a form, 00:17:23.980 --> 00:17:28.980 it'll say your selection of taxis has expired and you got to do it again. 00:17:29.880 --> 00:17:35.020 This one automatically, I saw it while I was waiting for you to talk about your new course 00:17:35.020 --> 00:17:35.560 and bundle. 00:17:35.560 --> 00:17:40.520 That thing just did a little flicker and regenerated its validation with no user input, 00:17:40.520 --> 00:17:41.620 just in the background. 00:17:41.620 --> 00:17:42.300 Telling you. 00:17:42.300 --> 00:17:42.660 Come on. 00:17:42.660 --> 00:17:44.460 So how does it know you're not a robot? 00:17:44.460 --> 00:17:45.020 Do you know? 00:17:45.020 --> 00:17:51.340 It runs some JavaScript and it also, I think, you know, I don't remember all the details. 00:17:51.340 --> 00:17:55.900 It runs through a bunch of other heuristics that like they know from, I think from your 00:17:55.900 --> 00:18:01.780 IP address talking to, because, you know, Cloudflare like fronts something like 25% of the internet. 00:18:01.780 --> 00:18:04.960 So they can tell if you're going to a bunch of different sites and things. 00:18:04.960 --> 00:18:06.640 And it kind of uses that background information. 00:18:06.640 --> 00:18:07.220 I think. 00:18:07.220 --> 00:18:08.140 I think. 00:18:08.140 --> 00:18:12.560 But anyway, I have not even had to find a taxi to be able to submit that. 00:18:12.560 --> 00:18:17.240 But it's made it so that you don't have a bunch of automated stuff coming in. 00:18:17.240 --> 00:18:17.720 Exactly. 00:18:17.720 --> 00:18:20.960 People used to be hammering on it, doing all sorts of bad stuff. 00:18:20.960 --> 00:18:21.420 Yeah. 00:18:21.420 --> 00:18:22.180 That's not good. 00:18:22.180 --> 00:18:22.960 Yep. 00:18:23.800 --> 00:18:30.520 So, yeah, I had to add it for like the login page and for the registration page. 00:18:30.520 --> 00:18:31.700 A bunch of bots were signing up. 00:18:31.700 --> 00:18:35.280 I'm like, I don't understand why they're signing up because it's a free account and you don't 00:18:35.280 --> 00:18:36.440 really get anything for free. 00:18:36.440 --> 00:18:39.540 So I couldn't understand why they were all, but hundreds of them were signing up. 00:18:39.540 --> 00:18:41.100 I'm like, okay, I'm going to do something. 00:18:41.100 --> 00:18:43.700 And then this is an improvement over reCAPTCHA. 00:18:43.700 --> 00:18:44.860 All right. 00:18:44.860 --> 00:18:45.480 PyBay. 00:18:45.480 --> 00:18:48.480 PyBay is coming up October 8th. 00:18:48.480 --> 00:18:55.700 I will be there speaking about Python type hints and how you can superpower your apps. 00:18:55.700 --> 00:19:00.020 Something like five amazing ways and tools you can use with your apps, I believe is what 00:19:00.020 --> 00:19:02.140 my topic is roughly supposed to be. 00:19:02.140 --> 00:19:08.520 But I will be there and people can, they happen to be in the San Francisco area or wanting to 00:19:08.520 --> 00:19:08.780 be there. 00:19:08.780 --> 00:19:09.860 They can check it out. 00:19:09.860 --> 00:19:11.280 They gave me a coupon. 00:19:11.280 --> 00:19:13.060 It's a friend of speaker. 00:19:13.060 --> 00:19:16.780 If you use that friend of speaker, no spaces, you get 20% off regular tickets. 00:19:16.780 --> 00:19:18.200 So that's always fun. 00:19:18.560 --> 00:19:18.760 Nice. 00:19:18.760 --> 00:19:19.220 Yeah. 00:19:19.220 --> 00:19:22.240 Always a fun trip, a road trip down to San Francisco. 00:19:22.240 --> 00:19:27.280 And let's see, following up on your doc strings, we got some really nice follow up here, Brian. 00:19:27.280 --> 00:19:34.500 Rhett Turnbull says, with regard to the doc strings article Brian covered last episode, the Google 00:19:34.500 --> 00:19:37.820 format allows for a raises section. 00:19:37.820 --> 00:19:41.320 Remember I said, oh, it'd be awesome if you could say actually what errors could happen. 00:19:41.320 --> 00:19:41.880 Yeah. 00:19:41.880 --> 00:19:42.520 That's really cool. 00:19:42.520 --> 00:19:47.120 And Rhett uses Google doc string format for projects, type hints, descriptive variable names, 00:19:47.500 --> 00:19:49.480 MK docs and MkDocs strings. 00:19:49.480 --> 00:19:52.820 Get pretty docs are free and VS Code will pull doc strings. 00:19:52.820 --> 00:19:57.180 So you can see them in the editor and copilot practically writes the doc streams for you, which 00:19:57.180 --> 00:19:57.740 is excellent. 00:19:57.740 --> 00:20:00.900 And one second attribution. 00:20:01.220 --> 00:20:04.100 John Hagan sent over something saying pretty similar. 00:20:04.100 --> 00:20:08.480 Say, remember we said, look, you don't necessarily need to include the type in the doc string. 00:20:08.480 --> 00:20:11.240 If there's a type hint and sure enough, you don't have to. 00:20:11.240 --> 00:20:11.820 Oh, cool. 00:20:11.820 --> 00:20:13.700 You can just give it a description, which is cool. 00:20:13.900 --> 00:20:17.020 And also points out the syntax for how you use the raises. 00:20:17.020 --> 00:20:20.800 So you say raises and you give it a list of exception types. 00:20:20.800 --> 00:20:24.400 And then the description of when the scenarios, when that might happen. 00:20:24.400 --> 00:20:27.480 So for example, raises invalid factorial error. 00:20:27.480 --> 00:20:30.880 If, and is less than zero is the time that that happens. 00:20:30.880 --> 00:20:31.560 Oh, cool. 00:20:31.560 --> 00:20:32.020 Isn't that cool? 00:20:32.020 --> 00:20:32.520 Yeah. 00:20:32.520 --> 00:20:32.980 Yeah. 00:20:32.980 --> 00:20:39.460 And finally, John also points out that PyCharm has the integration for Google, 00:20:39.460 --> 00:20:42.380 doc strings somewhere in here. 00:20:42.380 --> 00:20:42.880 Yeah. 00:20:42.880 --> 00:20:45.860 for Google doc format and how to set that up. 00:20:45.860 --> 00:20:50.420 So it'll, it'll automatically auto complete and render Google doc strings. 00:20:50.420 --> 00:20:55.160 When you say, give me the quick help control Q and it'll like, just pop that up as a 00:20:55.160 --> 00:20:56.420 rendered sort of thing there. 00:20:56.420 --> 00:20:58.740 So a lot of followup on the doc strings. 00:20:58.740 --> 00:20:59.440 Awesome. 00:20:59.440 --> 00:20:59.880 Cool. 00:20:59.880 --> 00:21:00.220 Yeah. 00:21:00.220 --> 00:21:02.460 And that's all I got for my extras. 00:21:02.460 --> 00:21:03.380 How about a joke? 00:21:03.380 --> 00:21:04.000 What do you think? 00:21:04.000 --> 00:21:04.400 Yeah. 00:21:04.400 --> 00:21:04.740 You ready? 00:21:04.740 --> 00:21:06.140 I've got your joke. 00:21:06.140 --> 00:21:08.680 And then I want to do a dad joke also after that. 00:21:08.680 --> 00:21:09.120 Awesome. 00:21:09.120 --> 00:21:11.740 So this one is a lesson in optimization. 00:21:11.740 --> 00:21:14.400 Careful what you measure, careful what you ask for. 00:21:14.400 --> 00:21:14.700 Right? 00:21:14.900 --> 00:21:18.320 So there's this picture of two tennis ball containers. 00:21:18.320 --> 00:21:20.120 You know, those tubes that are vacuum sealed. 00:21:20.120 --> 00:21:20.540 Yeah. 00:21:20.540 --> 00:21:22.920 One of them is not at all optimized. 00:21:22.920 --> 00:21:29.560 It stores only three tennis balls, but the one to the right says, look, if you cut the 00:21:29.560 --> 00:21:34.680 tennis balls in half, you can, you can store six tennis balls in this container way more 00:21:34.680 --> 00:21:35.440 efficient use. 00:21:35.440 --> 00:21:36.560 Yeah. 00:21:36.560 --> 00:21:37.280 Yeah. 00:21:37.280 --> 00:21:40.780 I mean, your tennis game might suck, but that's awesome. 00:21:40.780 --> 00:21:41.380 Yeah. 00:21:41.380 --> 00:21:41.960 Yeah.

than the other or 00:22:01.040 --> 00:22:01.900 it's longer than the other? 00:22:01.900 --> 00:22:02.300 Yeah. 00:22:02.300 --> 00:22:03.300 Do you know why that is? 00:22:03.300 --> 00:22:04.200
