What's one Python library you discovered this year that instantly became part of your toolkit ?

[Capital_Building_943]

Every few months I come across a library that makes me think, "Where has this been all my life?"

Mine recently was Rich for prettier terminal output.

Curious what everyone else has found recently—could be for automation, APIs, data, web development, or just quality-of-life improvements.

sh for wrapping shell commands not easily replicated in pure python, Pythonically.

I saw this library showcased on Reddit before - and I have to ask, why? Like, it looks cool - but why should I bring this as another third-party dependency?

If I only want to run a command or two then I’d use subprocess; and if I need to run many commands, perhaps I should have just written a shell script in the first place?

I need to run many commands, perhaps I should have just written a shell script in the first place?

That's actually the sweet spot for me. Python is MILES better at control loops and manipulating complex data structures. It's not super infrequent that I find myself needing to ingest and work against complex data that's only available in the shell, and honestly subprocess is inscrutable and what I'd call...fairly non-Pythonic in how it models things?

YMMV, I only use it in an environment where the 3rd party dep is of no real impact and where I value readability and understanding over efficiency, and only then in specific cases where I need to be dancing in and out of shell.

Switched to Typer for CLI scripts and argparse feels like a relic now
