The review is spot on about the typesetting in the book; it is terrible and is a deterrent to enjoyment and utilization of the contents. I've never had this reaction to a book before; I'm not really a font-obsessive kind of guy. They would have been better off just sending the humongous PyMOTW PDF to the printer.
My favorite Python reference is Python Essential Reference (4th ed) by Beazley; it pretty much lives up to its title. Among other things it is good at identifying points where Python2 and Python3 diverge.
