I think so, at least. Based on Tim's pointer about __subclasses__()
in 2.2, I can automatically generate an instance of all of my
subclasses.
class Flower(object):
def __repr__(self):
return self.__class__.__name__
class Gladiolus(Flower): pass
class Runuculus(Flower): pass
class Chrysanthemum(Flower): pass
class Rose(Flower): pass
class CrystalPassion(Rose): pass
print [Klass() for Klass in Flower.__subclasses__()]
Output:
[Gladiolus, Runuculus, Chrysanthemum, Rose]
Note that you'd have to do a recursive call to get all the classes
in the tree, as __subclasses__() only goes one level down.
