Description

This datasource returns Python releases from the python.org API.

It also fetches deprecated versions from the Endoflife Date datasource.

Because Renovate depends on containerbase/python-prebuild it will also fetch releases from the GitHub API.

Example custom manager

Below is a custom regex manager to update the Python versions in a Dockerfile. Python versions sometimes drop the dot that separate the major and minor number: so 3.11 becomes 311. The example below handles this case.

ARG PYTHON_VERSION=311
FROM image-python${PYTHON_VERSION}-builder:1.0.0
