[Python] Chunks of async_generator

I can get chunks of an iterator doing as follow:

def get_chunks_it(l, n):
""" Chunks an iterator `l` in size `n`
Args:
l (Iterator[Any]): an iterator
n (int): size of
Returns:
Generator[Any]
"""
iterator = iter(l)
for first in iterator:
yield itertools.chain([first], itertools.islice(iterator, n - 1))


Now let's say I have an asynchronous generator (python 3.6):

async def generator():
for i in range(0, 10):
yield i
await asyncio.sleep(1)


How could I get chunks (let's say of size 3 that would yield [0, 1, 2], [3, 4, 5], [6, 7, 8], [9]) of the resulting async_generator so that I could write:

async for chunk in get_chunk_it_async(generator(), 3):
print(chunk)
