Actually, the guidelines specify how the scripts should be named, so that users can use a sane "default" but also explicitly request a specific version:
https://fedoraproject.org/wiki/Packaging:Python#Naming

There are two cases:
1) If the script works the same under both python2 and python3, only the python3 scripts can be packaged

2) Otherwise, there should be /usr/bin/script, /usr/bin/script-2, /usr/bin/script-2.7 for Python 2, and /usr/bin/script-3, /usr/bin/script-3.5 for Python 3.
You could do that with something like this:

%py3_install
mv %{buildroot}/%{_bindir}/grafana-dashboard %{buildroot}/%{_bindir}/grafana-dashboard-3 
ln -s %{buildroot}/%{_bindir}/grafana-dashboard-3 %{buildroot}/%{_bindir}/grafana-dashboard-%{python3_version}

%py2_install
ln -s %{buildroot}/%{_bindir}/grafana-dashboard %{buildroot}/%{_bindir}/grafana-dashboard-%2
ln -s %{buildroot}/%{_bindir}/grafana-dashboard %{buildroot}/%{_bindir}/grafana-dashboard-%{python2_version}

Thanks for the info, so number 1 should be the case. grafana-dashboard will work for both python2 and python3.  So, If I am reading both comments, I don't think I need to make any changes?  Since python3 installs after python2?

Otherwise, I don't have an issue setting up the symlinking above for #2. I was hoping you might has an example package I could look into as I still have some questions and looking at the code always helps.

Right, looks like #1 is right for you.
You should just remove %{_bindir}/grafana-dashboard from the python2 package, since it's the python3 version (and it's already in the python3 package).

Hello Paul,

do you need any help adding Python 3 support to the RPM?

If you need more instructions, a [guide] for porting Python-based RPMs is available.

Sorry for the delay, I thought I fixed this already.  Apparently not, I'll work on it next week.

Sigh, I will learn to use bugzilla one of these days.  Thanks for fixing, I was trying to set the status to assigned.

Hi Paul,
could you please do the change suggested in the Comment #3? python2-grafyaml still depends on both 2 and 3.

This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle.
Changing version to '27'.

Hello Paul,

I created a Pagure PR that fixes "python2-grafyaml requires both python2 and python3" according to the Comment #3:

https://src.fedoraproject.org/rpms/python-grafyaml/pull-request/1

May I ask you to review and rebuild?

Thanks.

Jan

In Rawhide, the python2 subpackage was removed entirely.
