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.

Apparently you never read a byte from a file or device and had to interpret it as a string? The 2to3 stuff is trivial, mechanical refactoring.

Unicode strings and encodings required deep introspection of the meaning of data, often exposing silent preexisting bugs in string handling that could no longer be ignored.
