Python Special Interest Group (SIG)
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 any and all issues and tasks related to Python in Fedora, including:
- packaging and optimizing the various Python runtimes,
- packaging Python libraries and applications,
- setting and improving standards for packaging them as RPMs,
- maintaining Python packages for Fedora
and much more...

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 are 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.
- When packaging PyPI project you can generate the initial SPEC file using pyp2rpm tool.
- You can generate a spec template for your new python package like this:
dnf install rpmdevtools && rpmdev-newspec -t pythonThat will generate a spec file template that is a good starting point to making your package. (Beware, the template might be outdated.)
Python SIG FAS group
You can add python-sig group 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 src.fedoraproject.org.
The packaging dashboard of the Python SIG FAS group might serve as a place to start contributing.
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 Python 3
Python 2 is dead upstream as of January 2020. Thankfully the switch from Python 2 to Python 3 in Fedora is nearly finished, see our Fedora Porting Database.
If your project still doesn't work on Python 3, we recommend trying the Conservative Python 3 Porting Guide.

Python Fedora Changes
See the History of Python Changes
RPM package - The standard CPython implementation of Python 3
- The legacy CPython implementation of Python 2
- Python 2 implementation on top of the Java virtual machine
- An alternate Python interpreter (with a JIT-compiler) written in a subset of python, compiled to .c. The interpreter has better memory use than CPython and speed is closing in on CPython. The JIT'd version is faster than CPython in many benchmarks. It is growing the ability to load CPython extension modules.
- Alternative Python versions so you can test you code on all of them. Just
dnf install toxon Fedora 25+ to get them all.
- Python to C++ compiler (for a subset of Python with "implicit types")
- Python in Fedora
- Python packaging Guidelines
- Fedora Loves Python site (source repo)
- Python section in the Fedora Developer Portal (remember to update this as recommendations and the available tooling change!
- Python Patches – registry of patch numbers for Python interpreters in Fedora and EL
- Fedora Python interpreters maintenance guide
