Is it safe to change python3.11 to 3.12 by default ?

[kgdrenefort]

Hello,

If I was not on Gentoo, I'll not even question myself. But since Python is the core of portage and must of the Gentoo's stuff, as stated by the wiki, I would like a confirmation.

Is using the package app-eselect/eselect-python to move from 3.11 to 3.12 is risky ?

I would not want to fix my Gentoo for such a «trivial» things as my Python's default version.

Eselect python is not a thing for quite some time. Are you sure you know what you're doing and why you want to do it?

I don't know python, but I know there's this thing virtual environment, can't you create and work inside of one?

Most likely you won't be able to get rid of python 3.11 anytime soon.

p.s. pydoc doesn't seem to support 3.12 yet:

Changing python-exec's default (done by either editing /etc/python-exec/python-exec.conf or using the old eselect python) is always safe as far as portage-installed packages go, this is just for your own preferences really. Portage-installed packages will still use 3.11 if they can't use 3.12 yet (aka built without PYTHON_TARGETS="python3_12").

By changing python-exec's default your own python/python3 shebang scripts will use 3.12 if that's just what you want, albeit without python3_12 target on system packages you won't have access to a lot of system-wide python site-packages (doesn't matter if using virtualenv/pip or just stdlib).

python3_12 target will become a default "likely" in 2-3 months if it goes like usual, you *could* use it now but given a lot of packages haven't been migrated yet you'll still need to keep 3_11 as a target a well. Generally this is not worth bothering with, just let the distro handle this for you.

Thanks for these answers.

But I'll add I do not want to remove Python3.11, just have 3.12 as default, if it's safe.

And it's not even about my script, the shebang make my system use 3.12 anyway, but I didn't checked in detail, will take a look at it.

I'll just in case backup my system before proceeding.
