I sat silent at europy in 2006 as guido explained he was breaking the print statement. At europy in 2007, when he gave the same talk, I boo-ed, loudly. He said "well no-one complained when I talked about this last year." My bad.
Being able to instantly pepper my code with print statements is how I (and many others) debug. It really gives me the shits these extra parens.
print "Hi"
vs
print("hi")
Other than that, as Alex said there isn't much difference between the two.
