Michael #1: OverflowAI Integration of generative AI into our public platform, Stack Overflow for Teams, and brand new product areas, like an IDE integration. Have a conversation about the search results and proposed answer with GenAI Coming with IDE integration too. Check out the video on their page for some more detail than the article. Brian #2: Switching to Hatch Oliver Andrich Hatch has some interesting features Template built from hatch new myproject includes isolating dev, test, lint virtual environments. Each env can have scripts Test matrix ala tox, but possibly easier to express complex matrices. May not even need tox then, but then now you have hatch. A way to specify which optional dependencies needed for default environment. Notes from Brian One premise is that lots of projects are now using hatch. I don’t know if that’s true. A quick spot check of a few projects include projects that use hatchling. While hatchling is the back end to hatch, they are not the same. I use hatchling a lot now, but haven’t picked up using hatch. But I do want to try it more after reading this article. Michael #3: Alpha release of the Ruff formatter vis Sky Kasko Charlie Marsh announced that an alpha version of a Ruff formatter has been released in Ruff v0.0.289. The formatter is designed to be a drop-in replacement for Black, but with an excessive focus on performance and direct integration with Ruff. Sky says: I can't find any benchmarks that have been released yet, but I did some extremely unscientific testing and found the Ruff formatter to be around 5 to 10 times faster than Black when running on already-formatted code or in a small codebase, and 75 times faster when running on a large codebase of unformatted code. (The second outcome probably isn't very important since most people would not often be formatting thousands of lines of completely unformatted code.) For more info, see the README: https://github.com/astral-sh/ruff/blob/main/crates/ruff_python_formatter/README.md Brian #4: What is wrong with TOML? Colm O'Connor Suggested by Will McGugan This is a comparison of TOML vs StrictYAML under the use case of “readable story tests”. TLDR; For smallish things like pyproject.toml, toml is fine. For huge files, something like StrictYAML may be less horrible. from Brian: Short answer: Nothing, unless you’re doing crazy things with it. Re “readable story tests”: WTF? Neither of these are something I’d like to maintain.

Usually Tuesdays at 11am PT. Older video versions available there too. Brian #1: Heliclockter - Like datetime, but more timezone-aware Suggested by Peter Nilsson The library exposes 3 classes: datetime_tz, a datetime ensured to be timezone-aware. datetime_local, a datetime ensured to be timezone-aware in the local timezone. datetime_utc, a datetime ensured to be timezone-aware in the UTC+0 timezone. Michael #2: Wagtail 5 Wagtail is the leading open-source Python CMS, based on Django. Anything you can do in Python or Django, you can do in Wagtail. Wagtail 5.0 provides even more options for your content creation experience Dark mode has arrived SVG support Enhanced accessibility checker Delete more safely Some breaking changes in it because this release removes some of the old code paths that were maintained to give people more time to adapt their code to the new upgrades Add custom validation logic to your Wagtail projects. You can now attach errors to specific child blocks in StreamField. Brian #3: Git log customization Justin Joyce Just a simple git log --oneline makes the log so much more readable, but don’t stop there. --graph helps to show different branches -10 shows the last 10 commits. And this beauty in .gitconfig makes git lg mostly do what you want most of the time: [alias] lg = log --graph -10 --format='%C(yellow)%h%Creset %s %Cgreen(%cr) %C(bold blue)[HTML_REMOVED]%Creset' Michael #4: MiniJinja template engine MiniJinja is a powerful but minimal dependency template engine for Rust compatible with Jinja/Jinja2 Comes with integration back into Python via minijinja-py package. MiniJinja has a stronger sandbox than Jinja2 and might perform ever so slightly better in some situations. However you should be aware that due to the marshalling that needs to happen in either direction there is a certain amount of loss of information.

Follow up from docstrings: From Rhet John Hagen: You can certainly omit the type information from the docstring when you are using typehints. This is the way I've seen almost all modern usages of Google style docstrings nowadays. They still have some examples that include the type information because the original standard pre-dated Python 3 type annotations. Here is a simple example: https://github.com/johnthagen/python-blueprint/blob/main/src/fact/lib.py#L5 This also shows off the next point that you brought up: can I document all of the exceptions that a function could raise. Google docstrings have the "Raises:" block for this, and I find it pretty nice and concise for when this is needed. Also, PyCharm can be configured to autocomplete and render Google style docstrings https://www.jetbrains.com/help/pycharm/settings-tools-python-integrated-tools.html Tools | Python Integrated Tools | Docstrings | Docstring Format: Google What's nice about this, is that then PyCharm will render the google style docstrings in the Quick Doc function (Ctrl+Q), making the headers bold and larger and lists look nice so it's easy to read.

Michael #1: mpire A Python package for easy multiprocessing, but faster than multiprocessing MPIRE is faster in most scenarios, packs more features, and is generally more user-friendly than the default multiprocessing package. Tons of features. Nice intro article with benchmarks. Brian #2: mopup - the macOS Python.org Updater Glyph Lefkowitz On a mac, install Python with the standard Python.org installer. Then, periodically, update with python3 -m mopup I just did it and went from Python 3.11.4 to 3.11.5 See also Get Your Mac Python From Python.org for reasons to use python.org over other ways, also from Glyph. Michael #3: Immortal Objects for Python Instagram has introduced Immortal Objects – PEP-683 – to Python. Brian #4: Common Docstring Formats in Python Scott Robinson I don’t mean to disrespect Scott, but I’m honestly curious if this is really common. I like docstrings for the “why” of a function.

Its goal is to be as ergonomic as possible, while doing the right thing by default, while minimizing potential for misuse. General additions on top of Tenacity Retry only on certain exceptions. Exponential backoff with jitter between retries. Limit the number of retries and total time. Automatic async support. Preserve type hints of the decorated callable. Count (Prometheus) and log (structlog) retries with basic metadata, if they’re installed. Easy global deactivation for testing.
