Python 3.1 Readiness

Python 3.1 support graph for the 360 most popular Python packages!

What is this about?

Python 3.1 is a version of Python that is past its End Of Life. This site shows Python 3.1 support for the 360 most downloaded packages on PyPI:

  1. 359 green packages (99.7%) have dropped support for Python 3.1;
  2. 1 uncolored packages (0.3%) still support Python 3.1.

Package 'x' is uncolored. What can I do?

There can be many reasons a package is still supporting Python 3.1:

  • If you are package maintainer, it's time to start dropping support (if you haven't already). Here is an in-depth guide to Dropping support for older Python versions. If you are not able to give the time needed, please seek for help from the community.

  • If you are user of the package, send a friendly note to the package maintainer. Or fork it, and send a pull request to help move the project towards dropping Python 3.1 support.

How do you identify Python 3.1 support?

We look for the Programming Language :: Python :: 3.1 classifier on the latest release of the project, via PyPI's JSON API.
