Python Special Interest Group

Python is a high-level, interpreted programming language which emphasizes on code readability. Fedora loves Python and this SIG is for people who would like to see this relationship flourish. We aim to address the issues and tasks related to everything-Python on Fedora which includes:

and much more...

Core Members

See SIGs/Python/Members_list for a list of our current core members.


Join Python SIG

We're always looking for new members to join us. Whether you're a new contributor or someone that's been around since the beginning, there are definitely ways you can help. Join Python SIG and:

  • Learn how to package new Python software
  • Work with teammates from the four corners of the world
  • Broaden your scope of working in open source communities and gain experience interacting in different areas
  • Build your portfolio by working on real-world projects

Areas of contribution

Packaging and maintaining Python applications

If you're just getting started with packaging Python modules for Fedora, here's some hints to get you started:

  • The Fedora Packaging Guidelines must be followed for any package. The Python specific guidelines are a good starting point.
  • You can generate a spec template for your new python package like this:
    dnf install rpmdevtools && rpmdev-newspec -t python
    That will generate a spec file template that is a good starting point to making your package.
  • When packaging PyPI project you can generate the initial SPEC file using pyp2rpm tool.

Python SIG FAS group

You can add group::python-sig to your package so the core members of the python-sig get notified on each bug in your Python program. This way it is possible to maintain all Python packages with the group permissions, which will simplify general Python cleanup changes.

If there is interest and shown familiarity with our guidelines and processes (which usually manifests in maintaining at least 5 to 10 Python packages) you can apply for having access to a broader group of packages that is commonly maintained. If you choose to apply for this, please discuss it with a sponsor of the python-sig. (You can find a list of those in FAS.)

The current list of packages maintained by the python-sig can be found at the package database.

Review Python packages

If you are one of the experienced Python packagers, you can help with the list of Python packages awaiting review.

  • Bugzilla query for packages which have not passed review with "python" in the name or summary.

Porting to Python3

Currently there is an ongoing effort to port packages from Python 2 to Python 3, for the packages where upstream supports Python 3, so the package can provide either two subpackages for Python 2 and Python 3 respectively, or only the Python 3 version. This effort aims to completely shift to Python 3 before Python 2 retires in 2020.

Contributors interested in porting packages are encouraged to read the Python RPM Porting Guide

People who successfully port a number of packages are awarded the parselmouth badge, and a separate wiki page is maintained with contributor's names and the packages they ported: Python 3 Log

You can track the overall progress at Fedora Porting Database.
