By abstraction, the author mentions interfaces earlier on. I take the point of the other commenter who states that Java practitioners use too much abstraction, and would also point out that the later versions of Python add abstract base classes: http://docs.python.org/library/abc.html http://docs.python.org/library/abc.html After comparing Java and Python solutions on Rosetta Code: http://rosettacode.org/ http://rosettacode.org/ I think new programmers would find it easier to learn when using Python. - Paddy.
