/me thwacks Chris with a halibut.


Not only is "class variable" ambiguous, but Python uses different scoping 
rules for "variables" (name bindings) and attributes.

I don't know what language first decided to conflate object attributes 
and variables -- I suspect Java -- but it is actively harmful terminology 
(in Python at least, if not in general) and whoever invented it is bad 
and should feel bad.
