"if foo == None" is not wrong in any manner. It's just that if you are comfortable with the "is" operator and its semantics, "if foo is None" is slightly more natural. You generally use "==" if more than one object could be equal. If you know there's only one object of the kind, you convey that knowledge by the use of "is" even when functionally, it doesn't matter.
