Anthony Sottile and Brian discuss changes that would be cool for pytest, even unrealistic changes. These are changes we'd make to pytest if we didn't ahve to care about backwards compatibilty.Anthony's list:The import systemMulti-process support out of the boxAsync supportChanges to the fixture systemExtend the assert rewriting to make it modularAdd matchers to assert mechanismBan test class inheritanceBrian's list: Extend assert rewriting for custom rewriting, like checkpytester matchers available for all testsThrow out nose and unittest compatibility pluginsThrow out setup_module, teardown_module and other xunit style functionsRemove a bunch of the hook functionsDocumentation improvement of remaining hook functions which include examples of how to use itStart running tests before collection is doneSplit collection and running into two processesHave the fixtures be able to know the result of the test during teardownLinks:anthonywritescode - YouTubeanthonywritescode - Twitchpytest-asyncio · PyPIasync test patterns for pytestfuture-fstrings · PyPIre-assert · PyPInumpy.testingSourcegraph

I don't think it's too much of a stretch to say that software is part of most scientific research now. From astronomy, to neuroscience, to chemistry, to climate models.  If you work in research that hasn't been affected by software yet, just wait.But how good is that software? How much of common best practices in software development are making it to those writing software in the sciences?Patrick Mineault has written "The Good Research Code Handbook".  It's a website. It's concise.  And it will put you on the right path to writing better software. Even if you don't write science based software, and even if you already have a CS degree, there's some good information worth reading.Special Guest: Patrick Mineault.Links:The Good Research Code Handbookgame-wrath-jam: A game jam game, theme: WrathRobotron 2084 - Arcade - YouTubeThe Book of Why: The New Science of Cause and Effect

The first game I remember coding, or at least copying from a magazine, was in Basic. It was Lunar Lander. Learning to code a game is a way that a lot of people get started and excited about programming. Of course, I don't recommend Basic. Now we've got Python. And one of the game engines available for Python is PursuedPyBear, a project started by Piper Thunstrom. Piper joins us this episode and we talk about PursuedPyBear, learning to code, and learning CS concepts with game development. PursuedPyBear, ppb, is a game framework great for learning with, with goals of being fun, education friendly, an example of idiomatic Python, hardware library agnostic, and built on event driven and object oriented concepts.Special Guest: Piper Thunstrom.Links:PursuedPyBear | Unbearably Fun Game DevelopmentPiper's BlogMaking Games With PPB - PyTexasShooter Game by Piper Thunstromshootergame on GitHubBriefcase— BeeWaregame-blink: A tiny emergent behavior toy.Combat (Atari 2600) — The tank game I didn't remember the name of.Lunar Lander

PyPy is a fast, compliant alternative implementation of Python. cPython is implemented in C. PyPy is implemented in Python. What does that mean? And how do you test something as huge as an alternative implementation of Python?Special Guest: Carl Friedrich Bolz-Tereick.Links:PyPyHow is PyPy Tested? PyPy SpeedPython Speed Center

In Python, before dataclasses, we had attrs. Before attrs, it wasn't pretty.The story of attrs and dataclasses is actually intertwined.  They've built on each other. And in the middle of it all, Hynek.Hynek joins the show today to discuss some history of attrs and dataclasses, and some differences.If you ever need to create a custom class in Python, you should listen to this episode.Full TranscriptSpecial Guest: Hynek Schlawack.Links:attrs documentationHistory of attrs and introduction to attrs namespacecattrs: Complex custom class converters for attrs. — python-attrsPEP 557 – Data ClassesPEP 681 – Data Class Transforms

Will McGugan has brought a lot of color to CLIs within Python due to Rich.  Then Textual started rethinking full command line applications, including layout with CSS. And now Textualize, a new startup, is bringing CLI apps to the web.Links:richrich-clitextualTextualize.ioRich GalleryTextualize GalleryPython Bytes Podcast

When you are teaching someone web development skills, when is the right time to start teaching code quality and testing practices?Karl Stolley believes it's never too early. Let's hear how he incorporates code quality in his courses.Our discussion includes:starting people off with good dev practices and toolslintinghtml and css validationvisual regression testingusing local dev servers, including httpsincorporating testing with git hookstesting to aid in css optimization and refactoringBackstopNightwatchBrowserStackthe tree legged stool of learning and progressing as a developer: testing, version control, and documentationKarl is also writing a book on WebRTC, so we jump into that a bit too.Links:BackstopNightwatchBrowserStackProgramming WebRTC: Build Real-Time Streaming Applications for the Web by Karl Stolley

Being productive is obviously a good thing. Can we measure it? Should we measure it? There's been failed attempts, like lines of code, etc. in the past. Currently, there are new tools to measure productivity, like using git metrics.Nick Hodges joins the show to discuss the good and the bad of developer and team productivity, including how we can improve productivity.

Django has a handful of console commands to help manage and develop sites.  django-rich adds color and nice formatting. Super cool. In a recent release, django-rich also adds nice colorized tracebacks to the Django test runner. Links:django-rich · PyPIepisode 181: Boost Your Django DX - Adam Johnsondjango-crispy-formsPython Developers Survey 2020 Results
