According to the Fedora Packaging guidelines for Python , if a Python
package that supports Python 3 installs executables into */usr/bin*, then
either both Python versions of the executables should be packaged, or only
the Python 3 version, depending on the functionality they provide.
However, after going through all Python 3-compatible packages for Fedora,
we have identified up to ~30 packages which provide both python2- and
python3- subpackages with executables available only in the Python 2
version. For more information about obtaining the list refer to the
GitHub issue . The list of the affected packages is available here .
Before doing mass bug filing, I would like to post the list of packages
here, to get feedback or ideas on how this can be fixed in a better way and
encourage packagers to do the changes. If you are in Cc, then you are
owing at least one of the affected packages. The guide for porting
Python-based RPMs is available here  and you may refer to it for more
whisper as library is python3 compatible, the executables not yet (AFAIK).
