To add a native-speaker datapoint:

I am old enough to remember being taught the same as Greg.  (However,
American stylistic conventions have tended to get looser since then.)
I also remember going through manuscripts to get rid of contractions
prior to submission for publication.  Given the overloading of
apostrophe both in English and Python, I think 'does not' looks
slightly better than "doesn't" (which saves only one character and
forces a change in quote marks!).  So does consistency versus
accidental variation ;-)
