I agree with that. But > if (a, b) != (None, None): seems pretty straight-forward to me too. In fact, if anything, it seems easier to understand than > if (a is not None) or (b is not None): I certainly agree that things like > if a is not b is not None: ... belong in an obfuscated coding contest.

Make it dead-ass simple to understand, and future generations of programmers who inherit your code will thank you for it. -- https://mail.python.org/mailman/listinfo/python-list
