Chained comparisons get weird with not-equal operators. If you see a == b == c then it implies that a == c, but a != b != c does *not* imply that a != c. At least it doesn't in Python; I've never seen any mathematicians write that, so I don't know what they would make of it. -- Greg -- https://mail.python.org/mailman/listinfo/python-list
