aioitertools: itertools and more for AsyncIO¶
Implementation of itertools, builtins, and more for AsyncIO and mixed-type iterables.
aioitertools requires Python 3.6 or newer. You can install it from PyPI:
$ pip install aioitertools
aioitertools shadows the standard library whenever possible to provide asynchronous version of the modules and functions you already know. It’s fully compatible with standard iterators and async iterators alike, giving you one unified, familiar interface for interacting with iterable objects:
from aioitertools import iter, next, map, zip something = iter(...) first_item = await next(something) async for item in iter(something): ... async def fetch(url): response = await aiohttp.request(...) return response.json async for value in map(fetch, MANY_URLS): ... async for a, b in zip(something, something_else): ...
aioitertools emulates the entire
itertools module, offering the same
function signatures, but as async generators. All functions support
standard iterables and async iterables alike, and can take functions or
from aioitertools import chain, islice async def generator1(...): yield ... async def generator2(...): yield ... async for value in chain(generator1(), generator2()): ... async for value in islice(generator1(), 2, None, 2): ...
