Though I will admit that there are also NO OTHER REASONS for putting lazy imports in a context manager. It's just the backwards compatibility use case and no others.
I further contend that other than `contextlib.suppress`, there is no other situation where lazy imports in a context manager could be dangerous.
*Ahem* I hereby affirmatively state that the ONLY ergonomic way to functionally backport lazy imports would be to use a context manager. Even a *genius* could not come up with a better way.
I think I should have used Cunningham's law instead of asking questions in [this post](https://discuss.python.org/t/pep-810-explicit-lazy-imports/104131/176). I suspect I would have gotten more people weighing in.

Let me post a *non*-subtoot for once... We made a thing!

At least I'm teaching my children the valuable lesson that watching sports is boring and unpleasant.
First time going to a baseball game since I was a child and I am impressed with the degree to which every aspect of this is mild to moderately unpleasant, starting with the fact that in order to access the tickets it was *required* to download the "MLB Ballpark" app (which is apparently different from the "MLB" app).

Heads-up: pytest-cov 7.0.0 released today with a breaking change: it no longer coordinates subprocess measurement because coverage․py now does it for you. But you need to enable it with `[run] patch=subprocess` in your configuration.
Me: "We might go to a bookstore."
Son: "Aww, I don't want to go to a bookstore, it's probably very crowded because so many people like books."
Me: "Ha ha"
Bookstore: *actually is fairly crowded*
I told my 7 year old that if we moved to London he would probably get a British accent eventually and now every 5 minutes he worriedly asks me if he has started talking British yet (he has yet to interact with a British person).
My credit card when I buy gas on a highway near my house: "Seems pretty sus... 🤨"
My credit card when I order zero calorie sauces from Spain, delivered to someone else in the Netherlands, with that person's name as the cardholder: "All good bro, enjoy your sauces! 👍"
I can't tell if their fraud detection are not that good or if they just know me really well 😛

Do you dislike drafting long text messages on a mobile keyboard? Me too!
I created a little tool that lets you write text messages from a computer and then send them from your phone by scanning a QR code:

Oof, didn't realize that I didn't affirm my PSF membership this year and now the website is rejecting my password and when I try to reset it. Hopefully I can get it sorted out in the next... 90 minutes I guess? 😬

#blind I want to make the CLI app tools I use blind accessible. Did I correctly read that the better way is to create a local mini-website? (because the accessibility tools for browsers are so much better than for anything else?)
Or is a CLI tool automatically blind accessible because it is all text already?

Today we got our dishwasher fixed under warranty. To diagnose it, the tech stuck a photosensor+magnet onto the front panel over the green status LED and started reading diagnostics. It turns out the status LED is actually a serial port*, and it's continually transmitting status.
I can think of so many gadgets that could and should use this trick...
*It's probably something other than regular serial -- a UART's TX would flicker. I don't know any details.

The pytest.mark.parametrize feature is amazing, and more people should use it, especially people new to writing #Python tests. But it looks scary. I wrote an explainer: https://nedbatchelder.com/blog/202508/starting_with_pytests_parametrize.html

Interested in helping out with one of the most innovative, grassroots, publishing efforts around? The Journal of Open Source Software (@joss) is looking for editors: https://blog.joss.theoj.org/2025/08/call-for-editors
We conduct collaborative checklist-based peer review of research software using GitHub issues.
JOSS is a positive, rewarding, community-based reviewing/editing effort. I'm happy to answer questions if anyone is interested.
