from some_module import some_object
def print_attributes(obj, *attribs):
for attr in attribs:
print getattr(obj, attr, None)
class Foo(object):
type = 'A'
def print_attr(self):
print_attributes(getattr(someobject, self.type), *"BCDEFG")
class Bar(Foo)
type = 'B'
Still has a "code smell" thing to me, but hard to say not knowing the
