@aduh95 Thanks for opening this issue! I didn't know the right way to address this for PR nodejs/node#61177
As background for other readers:
Python version
3.9reached end of life transition and has moved to the list of Python unsupported versions:RHEL 9
According to
https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/9/html-single/installing_and_using_dynamic_programming_languages/index
the default version of Python is 3.9 on RHEL 9. Python 3.11 and 3.12 are also available.
AIX
and for AIX https://www.ibm.com/support/pages/aix-toolbox-open-source-software-whats-new it seems that Python 3.12 is available and moving to be the default version.

I noticed also .github/workflows/push.yml is using Python 3.9.
build/.github/workflows/push.yml
Lines 12 to 15 in 7e5e1cb
Should that be updated as well for consistency?

chore: migrate off Python 3.9
richardlau commentedon Jan 16, 2026
Opened #4220. I don't think the Python version used for linting the files in this repository needs to be consistent with the ones on the CI machines, but we should migrate from End-of-Life Python 3.9.
