Generator-based coroutine versus native coroutine

Question

I just read PEP0492 talking about the new approach on coroutines but the PEP failed to make me understand the difference between generator-based coroutines and native ones.

Answer 1

There is no functional difference. "Native coroutines" using the async and await keywords are just syntactic sugar for what was previously implemented in "generator-based coroutines."

The use of async and await is recommended in the 3.5 docs if there is no need to support older Python versions.
