[Tutor] Python 3.5.1 64 bit?

[yehudak .]

I'm using version 3.5 of Python and want to upgrade. The download site
doesn't mention whether it's 32 or 64 bytes. Any info if 64 bytes is
available?

Also, when I upgrade, does the newer version over-ride the old one or I
have first to remove the older version?

Thanks,
Yehuda
