Do you get confused by the difference between talking to Americans and
talking to Britons? The differences between American and British English is
a better analogy for the differences between Python 2 and 3 than the
differences between C and bash.

Especially if you target 2.7 and 3.3+, it is almost trivially easy to write
multi-dialect Python 2 and 3 code in the same code base. The trickiest part
is not a language change at all, but remembering that the names of some
standard library modules have changed.

Nobody here is suggesting that there are no differences between Python 2 and
3, but suggesting that those differences are of the same order of magnitude
as those between bash and C is ridiculous. The common subset of the Python
language is far greater than the differences between the versions.
