The "SECOND EDITION Covers Python 3" banner across the top of the
cover would seem to indicate otherwise. The first line of the About
section confirms it:

"This book is intended for people who already have experience in one
or more programming languages and want to learn the basics of Python 3
as quickly and directly as possible."

Unless you have a clear need for 3rd party libraries that currently
don't have 3.x versions, starting with Python 3 isn't a bad idea.
