I think this is a bug in the #Python argparse library. The following program, run with `./program --example 1`, fails with the error `program: error: ambiguous option: --example could match --example-a, --example-b`

I think it should complete successfully, printing `Namespace(example_a="1")`.

Worth filing a report? A fix?

✂️ --------------------

import argparse

parser = argparse.ArgumentParser(description='Fetch logs from Snapser API')
parser.add_argument('--example-a', '--example-b', help='example')

args= parser.parse_args()
print(args)

✂️ --------------------

(A workaround is to add `--example` as a third synonym.)

People in the #Python ecosystem, has there ever been a developer survey that gathered data about the *usage* of static analysis tools in the Python community? Frustratingly the JetBrains developer survey didn't seem to contain this question.

I know "AI" is a polarizing topic around here, but I wanted to share a small side-project I've been tinkering with to scratch a personal itch: MastoSum.

It’s a lightweight web app that listens to public streams, filters for the hashtags I actually care about, and uses an LLM to generate a daily digest of the last 24 hours. Basically, a personalized news feed to help cut through the noise.

It works reasonably well for what I need. Here’s an example of today's run: https://mastosum.linuxserver.pro/s/6q1ZdTOuHBfKyQ3aVU3dOw

It's IPv6-only. Not reachable via IPv4.

That One Draft Post (you know the one) that I've been working on for [unintelligible] months now had me wondering if I even remember how to _finish_ something, so, this was a brief interlude where I checked to see if I could in fact still do that. And also I wanted to write a little bit about #Python programming (a thing I actually like) and not just more about AI

There are a few things in this documentation that are technically documented just fine elsewhere, and that a high-level expert in #Python #SQL integration would be able to tell you about, but many, many product engineers would not realize that they need to look for in the first place.

"Wait… SQLAlchemy Core Support?", I hear you ask. Yes, #DBXS supports #SQLAlchemy Core, and has done so for quite some time. This was previously undocumented so I can certainly forgive you for not knowing.

So the *real* story of this release is not so much any big code changes, but rather updated dependency testing as well as *comprehensive documentation* for the SQLAlchemy feature. This may teach you a few things you didn't know about #Python database support. https://dbxs.readthedocs.io/en/latest/howto.html#sqlalchemy-core-support

“Someone I didn’t know created something I didn’t know I needed next” is the best thing about the #Python and #PyConUS community.

it's that time again #python

A couple go to Python debugging aids of mine, first is breaking into the debugger.

import pdb; pdb.set_trace()

The second is:
```
def printtb(fun):
import functools
@functools.wraps(fun)
def wrapper(*a, **kwa):
try:
return fun(*a, *kwa)
except:
import traceback; traceback.print_exc()
raise

return wrapper
```

Then any functions that is throwing an exception that I can't easily wrap elsewhere (or have no clue where it's being called from), I just throw this wrapper around it and I get the traceback I need.

The PSF Board has been developing a strategic plan and today we're sharing the high-level goals for community feedback. Full draft with detailed objectives follows in June.

This plan will shape how the PSF spends its resources for the next five years. If Python is part of your world, we'd love to hear from you.

OK @glyph challenge accepted. Here is python programming talk.

I have a script that uses "with Popen(...,stdout=PIPE)" to run a program and roughly run grep. Now I'd like to add a timeout, but I don't want to buffer the output (because it is unbounded), so run is out. Currently I am running /usr/bin/timeout from python, but this is, uh, unpythonic.

I’m proud that my work is helping to make the #HugoAwards happen again this year. When you vote in the Hugo Awards, or download the packet, you're using software I wrote. It's open source -- a rarity in convention software, but in my opinion, so critical to the trust we must have in the process -- and made with #Python and #Django and many other software libraries that are also freely given to the developer community.
