I can't believe i actually have to prove to you that creating a tuple and then testing for bool-inity takes more time than just the bool test, but here goes *another* Sunday school lesson... >>> s1 = "if (a, b) != (None, None):\n pass" >>> t1 = timeit.Timer(s1, 'a=1;b=1') >>> min(t1.repeat()) 0.23950232000015603 >>> s2 = "if a is not None and b is not None:\n pass" >>> t2 = timeit.Timer(s2, 'a=1;b=1') >>> min(t2.repeat()) 0.14334155999995346 > Tests that do, in essence, "if whatever in (constant1, constant2)" are > exceedingly common.

Yes, but not necessarily a "False" nothing! What is a True "something" and what is a False "nothing" Stephen?

No because i provide a very good reason --specifically in the case of a conditional bool-ing-- that integers bool-ing to True/False can be disastrous. And not only did i provide one reason, i provided two. The second being that 1/0 as compared to True/False is misleading in it's intention. Which renders code less readable, and supports bad programming styles. -- http://mail.python.org/mailman/listinfo/python-list
