This is a known issue — we're currently defaulting to a conservative Python version, and `datetime.UTC` really doesn't exist until Python 3.11!

https://docs.python.org/3/library/datetime.html#datetime.UTC

We will probably change the default to "most recent supported Python version", but as mentioned elsewhere, this is very early and we're still working out these kinds of kinks!

You should be doing this dynamically based on the version of python you are running against, so that you don't have to hardcode or make such "conservative" choices by hand.

[dcreager]

Note that we're not ever spinning up a Python interpreter to run your code, or monitoring an existing running Python process. So we do need some kind of metadata.

But yes, if you have a Python version specified in pyproject.toml, we respect that, and if you have a virtualenv, we can see the Python version that was used to create that. And that's what we use to type-check your code.

The default being discussed here is what we fall back on if that project metadata isn't available.

I think they probably know that, this is alpha software, no need to be condescending.

Criticism isn’t necessarily condescending. “You should be doing x because y” is just a plain assertion, it doesn’t imply any moral judgement or opinion of the author.

They said they will default to some newer version, which indicates they are not planning to do this dynamically.

How is it condescending in any way? I found it to be a constructive criticism; i.e. useful help.

I don't necessarily read it as condescending, but I do read it as presumptuous. What someone "should" do depends on many things. Maybe, because this is software in alpha stage, they should _not_ focus on this part of the code if it is minor compared to other obligations. Or maybe there are other reasons they've chosen not to do this (as was explained in an above comment).

IMO, a less presumptuous criticism would be phrased like "if you did X then benefits Y would happen", or "if you haven't, consider X", or even (the least presumptuous - make it a conversation!) "have you considered X?", rather than "you should do X".

[johnisgood]

I see what you mean. Perhaps it was just a "poor" choice of words for whatever reasons. I am sure we can assume he intended it in a way of "have you considered X?".
