> The usual way to do this is to forward to the __init__() method of the superclass for the common part. In your case you are just specializing the default arguments so all you have to do is pass the args to A.__init__():

I thought such kind of thing should be writted like:
class A(object):
     def __init__(self, blank=False, editable=True, name='foo'):
             self.blank = blank
             self.editable = editable
             self.name = name

class B(A):
  def __init__(self, blank=True, editable=True, name='foo'):
    super(B, self).__init__(blank, editable, name)
