Having recently (late last year) searched for a beginner's Python book for one 
of my kids, I can tell you that current offers range between "Only a few 
people use Python 3, so you're better off ignoring this odd duck while you 
learn" to "Python 3 is the future, so you may as well start be learning the 
future rather than the past".  I don't recall any current books that didn't at 
least acknowledge the existence of this Python 3 thing.

Based on that (admittedly incomplete) survey, I think confusion about the 
existence of Python/Python 3 is a problem with current dead tree learning 
Python editions.  If you're trying to learn something new with old 
documentation, I don't think it should be surprising there are a few bumps 
along the way.

I agree.
