python - Modifying ancestor nested Meta class in descendant -

suppose have:

class a(object):      class meta:         = "a parameter"   class b(a):      class meta:         = "a parameter"         b = "b parameter"

how can avoid having rewrite whole meta class, when want append b = "b parameter" it?

you subclass a.meta:

class b(a):         class meta(a.meta):         b = "b parameter"

now b.meta inherits attributes a.meta, , have declare overrides or new attributes.
