You could try the python package available in GNU ELPA. It hasn't gotten 
an "official" release in a while, but the development archive has new 
versions: https://elpa.gnu.org/devel/python.html

This is the same code as what comes by default with an Emacs build. 
Maybe it would make sense to bump the version so that there's a new 
non-devel release on GNU ELPA. That way, anyone on an older Emacs can 
benefit from the fix for this issue.
