About asyncio

from the package's own PyPI description — quoted content, verbatim

asyncio (obsolete backport)

This package once provided a backport of the asyncio module for Python versions prior to 3.4. The asyncio module has shipped with the Python standard library since Python 3.4 and this separate distribution is no longer needed.

Do not install this package. Use the implementation that comes with Python instead:

https://docs.python.org/3/library/asyncio.html

This release contains no code and exists only to prevent accidental installation of outdated backports.
