I didn't see gevent mentioned. Did asyncio make it obsolete?

Of all things, python went with async instead of gevent!

What's wrong with asyncio? For those of us not in the loop.

Think I'd rather use asyncio in this case. Assuming most recent Python might not be fair though I guess.

Can you explain why asyncio is not good?

kobzol May 22, 2023 View on HN

Hey now. Async in Python ain't that bad :)

how is asyncio overused? Its barely supported by popular libraries.

Maybe he meant gevent? Which is better than async io in python.

Anyone using an asynchronous python library? Interested in how that's shaping up.

Does Django's increasing levels of support for asyncio balance things back for you at all?
