__slots__ is used for memory and performance gains in classes that need them. A class with __slots__ has a fixed memory layout. Classes without __slots__ use a dictionary for storing attributes. It is possible to create a class that uses both __slots__ and __dict__ but it's very uncommon. Some people use __slots__ to restrict the attributes that can be set on a class (or instance). This is not the intended use, but it does happen. Tim Delaney -- http://mail.python.org/mailman/listinfo/python-list
