Thanks guys for your answers, it's clear (even if I wouldn't be able
to figure it out by my own).
About old style/new style

I have this class:
>>> class A:
... def __init__(self, blank=False, editable=True, name='foo'):
... self.blank = blank
... self.editable = editable
... self.name = name

>>> a = A()
>>> a.blank, a.editable, a.name
(False, True, 'foo')
All as expected.
