aioplus

Key Features

• builtins, itertools and more-itertools — but asynchronous;

• Seamless sync-async bridging (awaitify, anextify, etc.);

• Early returns never cause unawaited coroutine warnings.

Getting Started

Installation

The library is available as aioplus on PyPI:

pip install aioplus
