asynchrony

Python asyncio framework for writing safe and fast concurrent code.

Features:

• Type annotated and type safe
• Makes it easy to work with cancellation, errors, and scheduling.
• Well tested and well documented.
• Zero dependency.
• Based on real world experience and pain.

Installation and usage

python3 -m pip install asynchrony

A simple example of starting 100 tasks concurrently and waiting for all of them to finish:

from asynchrony import Tasks

async def download_page(url: str) -> bytes:
    ...

tasks = Tasks[bytes](timeout=10, max_concurrency=100)
for url in URLS:
    tasks.start(download_page(url))
pages = await tasks

See tutorial for runnable usage examples.
