Assertions for my exceptional friends, and Exceptions for my assertive friends! (Sorry. Sorry folks.)

Python Tip #139 (of 365): Use "assert" statements for yourself but exceptions for your users 🧵 And "users" INCLUDES other Python programmers who are using your code function/class/etc. #Python #DailyPythonTip

Maybe I’m weird but it’s ridiculously fun to get to show off a poster and I’m grateful that I got to do that at #PyConUS this year! Thanks for all the fun conversation and let’s keep that going. Open Source, Python, Science, Public Health: great things are possible with a great community.

It might be a while until you can watch Pablo Galindo Salgado’s #PyConUS keynote online, but watch it. It’s worth the wait.

Python Tip #91 (of 365): Use re.VERBOSE to make your regular expressions more readable 🧵 Regexes are extremely dense: one character is often a whole expression, and they're usually written without whitespace or comments: match = re.‍search(r"^\d{5}(-\d{4})?$", zip_code) #Python #DailyPythonTip

Here's canonzip. pypi.org/project/cano... A #python utility for producing stable zips and hashes from the contents of a directory. Exclude files with globs or just let it use your project's gitignore rules. CLI and API available. MIT licensed. Development was AI assisted but not vibe coded.

For my friends who are still using UV and might be a little weary about recent compromises to PyPi packages, stick this in your pyproject.toml. You can let all of those pip users find and report the compromises...

The recording of my talk on uv literally published yesterday. 💀 And I even said “I don’t think Astral would rug pull us.” Why did I tempt fate like that? astral.sh/blog/openai

Astral to join OpenAI

Two panel's from the graphic novel edition of Disney's Sword in the Stone. Wart (Arthur) remarks, "What a way to pack!" after witnessing Merlin use magic to pack his bags; Merlin replies, "Don't you get any foolish ideas that magic will solve all your problems. Now, develop your brain. Knowledge, wisdom. There's the REAL power."

Why learn to code when you can use an LLM and pay a subscription fee for the rest of your life.

Matthew Honnibal @honnibal.bsky.social · 6mo ago

I've been working on a post on LLM-assisted coding, and I guess I've built up a bunch of writer's debt, because it turns out there's a bunch of tangents I wanted to write up first. One really concrete thing that came up is try/except usage -- so, here's the post. honnibal.dev/blog/try-exc...

redirects wizardzines.com/comics/termi... (from "The Secret Rules of the Terminal", out now! wizardzines.com/zines/termin...)

redirect to a file:

cmd > file.txt terminal emulator into program, program out to file.txt, error out to terminal emulator
append to a file:

cmd >> file.txt terminal emulator into program, program out to file.txt (append mode), error out to terminal emulator
send a file to stdin:

cmd < file.txt file.txt into program, program out and err to terminal emulator
redirect stderr to a file:

cmd 2 > file.txt terminal emulator into program, program out to nowhere, err out to file.txt
redirect stdout AND stderr:

cmd > file.txt 2>&1 terminal emulator into program, out and err to file.txt
pipe stdout:

cmd1 | cmd2 terminal emulator into program 1, 1 out to program 2 via pipe, 2 out to command line, program 2 out 1 and 2 to terminal emulator
pipe stdout AND stderr:

cmd1 2>&1 | cmd2 terminal emulator into program 1, 1 and 2 out to program 2 via pipe, program 2 out 1 and 2 to terminal emulator
three gotchas

cmd file.txt > file.txt will delete the contents of file.txt some people use set -o noclobber (in bash/zsh) to avoid this

but I just have “never read from redirect to the same file” seared into my memory.

sudo echo blah > /root/file.txt doesn’t write to /root/file.txt as root. Instead, do:

echo blah | sudo tee /root/file.txt or sudo sh -c 'echo blah > /root/file.txt'

cmd 2>&1 > file.txt doesn’t write both stdout and stderr to file.txt. Instead, do: cmd > file.txt 2>&1

cat vs <

I almost always prefer to do:

cat file.txt | cmd

instead of

cmd < file.txt

it works fine & it feels better to me

using cat can be slower if if’s a GIANT file though
&> and &|

some shells support &> and &| to redirect/pipe both stdout and stderr

(also some shells use |& instead of &|)

Rather than spend 10 minutes manually exporting a bunch of Audacity clips to wav files, I asked AI if I could script that. “Of course!” 5 hours later, round about 2:00 AM, it was working flawlessly. Plus now I have a neat collection of 6 Audacity versions across 3 installation methods. Win-win!

Be wary of anything that enables you to fuck things up faster than you could on your own. This applies to AI in exactly the same way it applies to table saws.

Today, we’re announcing the preview release of ty, an extremely fast type checker and language server for Python, written in Rust. In early testing, it's 10x, 50x, even 100x faster than existing type checkers. (We've seen >600x speed-ups over Mypy in some real-world projects.)
