what's the difference?  both examples give syntax errors, btw,
even if you fix the capitalization.  and the __slots__ attribute
doesn't do much unless you inherit from object (etc)...

anyway, here are a few ways to split the slot line (or any tuple
or list literal) across multiple lines:

    class HasSlots(object):
        __slots__ = ('one', 'two', 'three')
        __slots__ += ('four', 'five')

    class HasSlots(object):
        __slots__ = ('one', 'two', 'three',
            'four', 'five')

    class HasSlots(object):
        __slots__ = (
            'one', 'two', 'three', 'four',
            'five'
        )
