Negative. The OP stated Python 3.2, in which Ned's statement is
correct. :) In Python 2.x, yes, input() will return an int if it
evaluates as one, but in 2.x, I would STRONGLY advise against ever
using non-raw input(). (To be honest, I'd have to say that the
innocuous name 'input' concealing code evaluation is an embarrassment,
and one that I'm very much glad is now removed from the language.)
