await vs yield from for python

Question

https://stackoverflow.com/a/44273861/433570 says 'yield from' is old and we should learn 'await'.
But It doesn't say they are the same thing or they are different.

But I have some good book and videos which talks about yield from

Can I think yield from was replaced by await? and they are essentially the same thing?

I have a book fluent python which also talks about yield from

Edit

When I see some good books/videos like the above talking about yield from, could I substitute yield from with await in my mind?

Does this answer your question? What does the "yield from" syntax do in asyncio and how is it different from "await" — Keegan Cowle

@testfile I even quoted the link in my op. It doesn't clearly say they are the same thing whether I can think of await as a new name for yield from — eugene

Yes they are the same thing. Yield is the manual way of doing async await. See https://www.python.org/dev/peps/pep-0492/#new-coroutine-declaration-syntax where they detail that async await is just a coroutine (yield) underneath

yield and await may be similar under the hood, but they aren't the same thing, and they're not interchangeable. I had code that wasn't working with await, I replaced await with yield and suddenly the code worked fine. I'm not sure why just that change fixed it, but it has me certain that they aren't "the same thing".
