Have python version update managed by renovate (not python dependencies)

[shadycuz]

Type of discussion.

I'm proposing an idea

Tell us more.

I have projects that depend on specific versions of Python. Like python 3.10.X, 3.9.X, 3.8.X etc. I use pyenv to specify which versions of python/s my project requires. This happens using the .python-version file.

The problem is when a new version of Python is updated. I have to manually change all these files, across all of my projects. It would be nice to have Renovate handle this for me.

One example would be if I had a .python-version file of:

3.10.4.

I would expect renovate to change it to:

3.10.5

It would also be nice if Renovate would remove versions when they were deprecated and add new versions of Python when they were generally available.

There might be multiple places where python versions are defined - including within tools like poetry and pipenv. To update them all:

• Renovate should recognize and be able to support them all
• Updates to Python should be grouped together so they're updated at the same time

If Renovate was updating such versions, in which scenario would you end up with a deprecated version? e.g. I can imagine that happening if the project ignores Renovate's PRs for years, but that doesn't seem like a useful scenario

Well supporting them all is very ambitious and I would be happy if you supported just my use case first =).

If Renovate was updating such versions, in which scenario would you end up with a deprecated version?

Imagine I have a python version file with one or more versions:

3.7.16 3.8.16 3.9.16

So in 1 month and two weeks, when 3.7.16 becomes EOL. I would expect Renovate to remove it from the .python-versions file.

3.8.16 3.9.16

I'm not familiar with the renovate code base but if its opensource, I might be able to take a shot at implementing this feature for the .python-versions use case. I'm not sure where we would source the data from. https://endoflife.date/python seems to have an API and it looks to be free.

Removing or adding versions is currently out of scope - Renovate does not have an elegant way to do that. Removing would probably be easier than adding.

The first step would be adding a pyenv manager to Renovate - I created a feature request here: #22225
