I have one project that's bound to Py2 by its one dependency, and I've
kept it Py3-compatible apart from the one block of code that sets that
up. (That includes renaming a function that was originally called
"await", even though that's not actually a keyword as of 3.6.) All the
rest of my code will run on Python 3. However, there is still a lot of
Python 2 code in my repos - it's the same code! Most of my stuff is
simple enough that I keep it 2/3 compatible. Sometimes there's a block
of code at the top to deal with {raw_,}input or a future directive or
a changed import name, but the bulk of the code is unchanged.
Of course, now that I go to actually *check*, it turns out that a lot
of my code has accidentally not been cross-version compatible. I use
the open(fn, encoding="...") form in quite a few places, so to make
that work, I would need "from io import open" (which seems to be a
safe no-op on Py3), and there are places where I use multi-arg
versions of print, which will end up displaying tuples in Py2 if I
don't slap in a __future__ directive. But that just means that I
really truly have *moved* to Python 3, to the extent that I don't
always even test my code on 2.7 any more.
