News The Move to Python 3 Begins!

As someone who spent decades in the mainframe community, I find it ... humorous ... that there are legacy Python2 code bases that are only just (or have yet to consider!) moving to Python3.

depending on the codebase, 2->3 is no joke and has so much risk

What do you mean? I migrated about 3-4 python projects from 2->3 about a decade ago and other than pandas and pandas related projects it was a breeze. Run 2to3.py and review. Barely a hiccup.

2to3 has been decrept (depending deprecation 3.9/fully decrept 3.11) and removed (since 3.13) for a while now.
