Python *does* provide multiple useful extensions that you might want to
double-click, namely .py and .pyw. It also provides an association for
.pyc; whether that is useful or not may be debatable.

This I also wonder about. Apparently, his editor has the capability of
running Python scripts, and then his question is how to make the editor
use a different Python version (and he assumed that there is the notion
of a "default" Python version in Windows, and that the editor would just
run the default).

I'm still very unsure as to what his editor actually does, but his
report of success seems to indicate that it choses the interpreter
associated with .py.
