Hi, I suggest to put such function in a Python module and publish it on PyPI. I'm sure that the module will quickly grow with more async flavor of existing functions. Victor On Tue, May 25, 2021 at 4:22 AM Filipe Alves Caixeta <filipecaixeta@gmail.com> wrote:

Hello,

Python 3.10 comes with the built-in anext() but I think we may be missing some other equivalent built-in functions like list and enumerate. I didn't discuss the idea of creating a PEP for this but I would like to get some help with the implementation.

The equivalent Python code would be

async def aenumerate(sequence, start=0): n = start async for elem in sequence: yield n, elem n += 1

The code for enumerate if here https://github.com/python/cpython/blob/2f3a87856c7033227577b9ed0c77ed7531143...

The next function creates a tuple and return with (n, elem)

result = PyTuple_New(2); PyTuple_SET_ITEM(result, 0, next_index); PyTuple_SET_ITEM(result, 1, next_item); return result;

For the async implementation I would have to instead return an async_generator_asend object and that would resolve to the tuple. Calling tp_as_async->am_anext and getting the value doesn't seem like the solution because I should not get the result at this stage yet.

I would like to have a hint on how to implement this =D
