One of my students wrote some code for Python 3, and when I went to
test it, I typed 'python scriptname' out of habit (most of my students
use Py2)... and it almost perfectly worked. The only part that didn't
was a class definition that didn't explicitly subclass object, and
then used @property. Just changing that class declaration would have
made his code 2/3 compatible - and he didn't put any effort into it at
all. He literally made his code *accidentally*
(almost-)Py2-compatible.

You don't need to be afraid of the gap.
