changing much of my Python code

[Skaperen]

If this is python 2 code that you want to convert to python 3, use the 2to3 utility. It will remove the unnecessary __future__ imports and probably keep the rest of the code working. Note that __future__ imports still exist in python 3.

i had been writing my code to work in both Python2 and Python3. now that Python2 is less than a year from EOL, i have decided to drop it entirely and only write for Python3. i don't need to use the 2to3 utility because all my code already works in Python3 (and most probably still also works in Python2, but i really don't care about that, anymore.

what do the __future__ imports do in Python3? i thought they did nothing, though i could believe that if a Python4 ever comes out that __future__ could have a new use.

if the 2to3 utility removes the __future__ imports then i suppose it is safe for me to do so. just doing only that should have no effect on running that code under Python3, right? if it runs OK with the __future__ imports under Python3, then it should also run without, right?

You can add:

from __future__ import annotations

PEP 563

The __future__ module is still used to introduce changes.
https://docs.python.org/3/library/__future__.html

none of my code imports annotations (yet). i can add that import if/when i use annotations, right?
