Yes, I didn't write that correctly. What's not inherited is the lack of a dictionary :) >>> class foo(object): ... __slots__ = 'a b c'.split() ... >>> class bar(foo): ... pass ... >>> set(dir(foo())) - set(dir(bar())) set([]) >>> set(dir(bar())) - set(dir(foo())) set(['__dict__', '__weakref__']) And you are correct that the rules are a bit complicated, but for my purposes (memory usage reduction on non-subclassed classes) __slots__ seem to work fine.
