asyncio-anywhere

Python package that makes it easy to run fast asyncio code

Are you trying to run async code in Python and getting the error asyncio.run() cannot be called from a running event loop? This package makes it easy to run asyncio-based async code in tricky execution environments:

• IPython-based notebooks (JupyterLab, AWS Sagemaker, Databricks, etc)
• trio applications
• curio applications

Other Features:

• Use uvloop for faster i/o - but without permanently changing the asyncio event loop policy
• Run any code which uses asyncio I/O.
• Type hints to support type-aware IDEs

Non-Features:

• asyncio-anywhere does not monkey-patch the asyncio module. This avoids unexpected side-effects and potential future bugs.

Usage

pip install asyncio-anywhere

import asyncio
from asyncio_anywhere import asyncio_run


async def myfunc():
    await asyncio.sleep(0.01)
    return "OK"


result = asyncio_run(myfunc())

print(result)

Use asyncio_run() anywhere where you would normally have run asyncio.run(). Note that it also accepts a boolean debug parameter as the second parameter.
