Python programming book

Can you recommend a Python programming book for a serious, professional 24-30 hour course for programmers?

I'd like to focus on advanced programming techniques and introduce them to functional programming, rather than teach them what's a while loop (that's assumed to be known) or just teach them syntax, functions and classes (I don't want a "translate Java into Python" course).
