102 years ago, in November 1923, someone in Germany posted a package (Christmas present, maybe) using 50 stamps of 200 million Mk. Hyperinflation.

Why PyPI is simply because that’s what’s accessible. I’d love to see an analysis of corporate codebases. If anyone has access to those, they can use my script - see the PEP for details.

That’s a good question, which was raised in the discussion. I repeated the analysis on a random selection of PyPI packages, and found that the incidence rate was double - about 4 per million LOC. so you are right that high quality code is less impacted, but not by orders of magnitude.

Tough choice..

“Joyful” is something we’re supposed to value now in a presidential candidate?

One of the criticisms against her was that she constantly laughed as the world burned on her watch.

Sure, my point is I rarely look at codeowners/experts (I do that when I am actively looking for help). It’s possible that someone was unaware of a relatively recent codeowners addition.

We had some discussions in the past about ‘codeowner’ being a misleading term here. The intention is that the person offers to resolve issues, not that they actually own the code.

I tag people when I need their input. If I can handle an issue myself I don’t bother them. I don’t tag as recognition.

Can you be more specific about what happened? Who did you expect to tag you, and on what? What does recognition as maintainer mean?

The PEP has now been accepted.

Which other languages have this problem?

LWN published a good summary of the discussion so far:

I'm working on CPython's internals documentation, collecting it all into one place, organising, updating and enhancing to fill in missing topics.

It's taking shape, but there are still gaps to fill. Contributions are welcome.

I would be interested to know what they mean by ‘Python is a poor investment’. Learning python? Building systems in Python? Working on Python?

Do they have a point? If they don’t then I’d disagree, but I wouldn’t feel angry or offended. Why should I?

You have unlimited data, so you can always get the email to let you know that you've run out.

If you use up all of your (unlimited) data, we will let you know.

Good bot.

PEP 765 – Disallow return/break/continue that exit a finally block | peps.python.org This PEP proposes to withdraw support for return, break and continue statements that break out of a finally block. This was proposed in the past by PEP 601. The current PEP is based on empirical evide...

I conducted an analysis of return-in-finally in real world Python code. Just don't do it.

TL;DR:
- it is not used often
- when it is used, it's usually used incorrectly
- code authors find it easy to fix
