## Detailed Description
The nautilus-python package allows Nautilus extensions to be written
in the Python scripting language. In Fedora releases up to and
including Fedora 29, these extensions were executed in a Python 2
environment. With the general move to Python 3 as Fedora's default
Python runtime and the impending deprecation of Python 2,
nautilus-python will execute extension code in a Python 3 context.
Compatibility with Python 3 will be required for all Python-based
(Note: In Fedora 28 the nautilus-python package was named
python2-nautilus. For Fedora 29 the name has been reverted to
nautilus-python to better indicate its status as a Nautilus
## Benefit to Fedora
In addition to eliminating nautilus-python's direct dependency on
Python 2, this change will remove all Python-based Nautilus extensions
from the list of Fedora components which still require the legacy
Python 2 interpreter (which has been deprecated, and is slated for
removal). It will allow us to ensure that all Python-based Nautilus
extensions still in use are fully compatible with Python 3.
Proposal owners: Build nautilus-python with Python 3 support and deploy.

## Upgrade/compatibility impact
N/A (not a System Wide Change)
## How To Test
Launch the Nautilus file manager and verify that any functionality
provided by Python-based extensions is still available.
## User Experience
As long as Python 3 compatibility is verified for all Nautilus Python
extensions, users will see no impact from this change. If any
extensions are not compatible with Python 3 and must be removed, users
may notice loss of certain functionality from Nautilus.
Any Nautilus extensions which use nautilus-python will have to be
checked for Python 3 compatibility. Repackaging should not be
necessary, as the nautilus-python dependency Required by those
packages will be carried forward to Python 3 builds.
The list of packages in the Fedora 29 repos which depend on
nautilus-python is, as of 2018-11-08:
## Contingency Plan
Continue shipping builds of nautilus-python based on Python 2.
