Hello,
According to:
https://www.python.org/dev/peps/pep-0492/#await-expression
an awaitable object is:
- A native coroutine object returned from a native coroutine function
- A generator-based coroutine object returned from a function decorated
with types.coroutine()
- An object with an __await__ method returning an iterator
I dont understand the last one.
For example in instruction "res = await obj"
where obj has a __await__ method returning an iterator
What kind of data this generator is supposed to provide when next()
is applied to it and what are these data becoming ?
what res contains when the iterator has finished to iterate ?
It seems that PEP492 documentation says nothing about it (or I dont
understand, english is not my native language)
