alt Hacker NewsNo, determinstic scheduling is not a property of async python.
Yes, the stdlib asyncio event loop does have deterministic scheduling, but that's an implementation detail and I would not rely on it for anything critical. Other event loops - for instance trio [1] - explicitly randomize startup order so that you won't accidentally write code that relies on it.

It's been a stable (and documented) behavior of the Python standard library for almost a decade now. It's possible it may change--nothing is ever set in stone--but that would be a large change in Python that would come with plenty of warning and time for adjustment.
How do you differentiate between something that "happens to work due to an implementation detail" and a "proper feature that's specified to work" in a language without a specification?
I just realized how little I know about how async event loops.

That sounds familiar...
