This code creates a new class attribute named "slots" and puts an empty list into it. The name "slots" has no special meaning other than identifying the new list.

Correct. One additional point: Using "slots" may have been less than ideal attribute name since it may get confused with the built-in attribute management variable __slots__ described in the Python data model docs.
