Python's pathlib module
Python's pathlib module is the tool to use for working with file paths. See pathlib quick reference tables and examples.

Still building file paths by gluing strings together?
Python's pathlib gives you Path objects that work the same on every OS. The tutorial has ready examples, like finding the file you changed last.

oh! Been working with my scripts and I've been using
__package__ = "your_package"
pathlib can also be imported with
__package__ = __package__ or Path(__file__).resolve().parent.name
make sure parentdir is on sys.path nested pkgs must be full dotted name
this ONLY works on 3.14 or older though

maybe I'll spelunk in `pathlib` and see if there's a sensible way to make the function variadic like this, and shove an `any()` in there

I tend to use "from" imports most because I prefer short and descriptive variable names:
from dataclasses import dataclass
from pathlib import Path
But if there's a name like choice that isn't as clear as random.choice, then I'd recommend importing the whole module for the more descriptive name.

okay right, refreshing my memory about how `pathlib` is implemented, I had forgotten about the "selector" abstraction, which does complicate matters.
`Path.glob(pattern)` ends up calling `_make_selector(tuple(pattern_parts), self._flavour)` and then yielding from `selector.select_from(self)` […]

I've read the impl of `pathlib` before but there's a lot of fuzz to it, so the details never stick in my mind beyond knowing that `Path` itself is a façade and that there's more machinery in there than you might think to handle all the variation across filesystems in maintainable/reusable ways

Python startup times just got faster.
In 3.15, you can use the keyword `lazy` to make a lazy import (`math` and `Path` below).
Lazily imported modules are only loaded
WHEN they're used, and
IF they're used.
Use them to defer loading of modules that may not be required.

But there is no corresponding "just the real actual stem", .stem includes all but the final suffix:

'foo.tar'
