Whereas the following will produce some sort of async lists, sets, and dicts?
result = [await fun() async for fun in funcs] result = {await fun() async for fun in funcs} result = {fun: await fun() async for fun in funcs}
If so, how do I read values from an async list/set/dict?
Consider "funcs" to be an asynchronous generator/iterable that produces a sequence of awaitables. The above comprehensions will await on each awaitable in funcs, producing regular list, set, and dict.
So, what's the "async" good for then?
I doubt that anybody ever would write something like that; this is just examples of what the PEP will enable.
Why do you implement it then? :D Put it differently, why are you sceptic about it?
There is no concept of asynchronous datastructures in Python.
I thought so, that's why I asked. ;) "async def" gives me something async, so I assumed it to be the case here as well. Cheers, Sven
