What are we using to package up Python application & dependencies into a single distributable file now?

I'm thinking of bundlers like RollupJS.

PEX? Zipapp? Docker image? Trying really dang hard to only use stdlib and shipping a boring wheel?

Every Python dev has faced APIs that use camelCase or kebab-case while your codebase follows snake_case.

The typical approach creates technical debt: either break Python naming conventions or write complex mapping logic that clutters your codebase.

Pydantic's Field alias feature elegantly solves this: define external field names through aliases while keeping internal code perfectly Pythonic.

Integration compatibility and clean code that's maintainable. 💚

And some good insight on #python's loss of conviviality: «Due to a combination of growing ecosystem complexity, growing corporate influence on development decisions, and the rise of a breaking-change version of Python (Python 3), the scientific Python ecosystem flipped from a stable infrastructure for research projects to an unstable software layer whose frequent breaking changes required researchers to invest more and more time just to keep their code in a usable state. Conviviality was lost.»

When thinking about #Python lists vs tuples: lists can be varying lengths and the elements will be treated the same. Tuples are namedtuples without the names.

https://nedbatchelder.com/blog/201608/lists_vs_tuples

Dear #Python folks, what’s the most Python-ic way to insert into a dict such that overwrites cause an error?

There are ways to silently overwrite (d[key] = value, update(…), etc) and ways to silently drop overwrites (setdefault). But the only way to detect and hard reject an overwrite seems to be to pre-check if the key is present.

Maybe it’s my 25+ years of Java instincts, but the part of my brain that’s been traumatized by race conditions wants something more resilient. Do I just embrace the GIL here and let go of my instincts? My Java instincts want something like java.util.ConcurrentMap’s putIfAbsent(key, value) method.

Not sure if this is useful to anyone other than me, but I made a TODO item linter that complains if the TODO items in your code don't have an owner and a reference to an issue so someone has a chance of addressing them in the future:
