No, it doesn't.

Honestly, if you are writing "play" scripts as you say, I wouldn't
bother trying to make them cross-version compatible. Move all your old
scripts to a "python2" subdirectory and forget them. Write new scripts
as Python 3 only. As an exercise in understanding the differences
between Python 2 and 3, porting some of the scripts in your "python2"
directory to Python 3 would possibly be a useful thing to do.

If you have important scripts that you use a lot that are in Python 2
form, continue running them under Python 2 until you have some time
(and maybe the understanding, if they are complex) to port them, and
then switch.
