I got it wrong too, even after reading the docs, until I just tried it for myself. Intuitively, why would Python have threads that can't run fully in parallel but also create race conditions? Seems like the worst of both worlds, and it almost is, except you can still speed up io-bound or even GIL-releasing CPU-bound C calls this way.

Some also mix it up with async JS which also can't use multiple CPUs and guarantees in-order execution until you "await" something. Well now that's asyncio in Python. Doesn't help that so much literature uses muddy terms like "async programming."
