Yes. In Python 3.0, doing non-equality comparisons with None will raise a TypeError because it's nonsensical to ask whether two objects of unrelated types are less than or greater than each other (e.g Is [1,2] > "ab" ?). Assuming `a` will never take on a value considered boolean false, you can do `if a and a > b:` instead.
