[Fedora-i18n-bugs] [Bug 1807534] New: pyzy requires Python 2 to build

https://bugzilla.redhat.com/show_bug.cgi?id=1807534

Bug ID: 1807534
           Summary: pyzy requires Python 2 to build
           Product: Fedora
           Version: rawhide
            Status: NEW
         Component: pyzy
          Assignee: [e-mail]
          Reporter: [e-mail]
        QA Contact: [e-mail]
                CC: [e-mail],
                    [e-mail], [e-mail]
            Blocks: 1803205 (BRPY27)
  Target Milestone: ---
    Classification: Fedora

Python 2 reached upstream end-of-life in January 2020. In Fedora Rawhide, it's
now provided from the compat package `python27`.
Packages that only use Python 2 at build time, like pyzy, had a general
exception to keep using it in Fedora 31. Now, the dependency should be removed.
Let us know if you need any help investigating or removing the dependency.
(There are dozens of packages like this, so we didn't investigate this one
thoroughly. We assume you know the package best.)

If it's possible that the dependency won't be removed in Fedora 33. Please
request a FESCo exception. You can refer to the exception for mercurial as an
example: https://pagure.io/fesco/issue/2243
It's good to mention:

- What is the reason for the Python 2 build dependency?

- What are the upstream/community plans/timelines regarding Python 2?

- What is the guidance for porting the build to Python 3? (Assuming that there
is someone who generally knows how to port to Python 3, but doesn't know
anything about the particular package, what are the next steps to take?)

If you need anything from us, or something is unclear, please mention it here.

- What is the reason for the Python 2 build dependency?

The pyzy project use Python 2 to convert the data format.

- What are the upstream/community plans/timelines regarding Python 2?

The upstream is not active since Dec 2012.

I see there is a pull request for Python 3 compatibility:
https://github.com/pyzy/pyzy/pull/4
Can that be used?
