For review: PEP 308 - If-then-else expression

What I think is more interesting is this code from Lib/unittest.py:

        self.stream.writeln("Ran %d test%s in %.3fs" %
                            (run, run == 1 and "" or "s", timeTaken))

When the and/or idiom causes a bug in the standard library's test module,
I think it's time to seek a more robust alternative :-)
