It looks correct -- at least it /looked/ correct before tried to quote it...
Here is an alternative approach that massages the initializer signatures a
bit to work with super() in a multiple-inheritance environment:
class Mother(object):
def __init__(self, p_mother, **more):
print "Mother", p_mother, more
super(Mother, self).__init__(p_mother=p_mother, **more)
class Father(object):
def __init__(self, p_father, **more):
print "Father", p_father, more
super(Father, self).__init__(p_father=p_father, **more)
class Child(Mother, Father):
def __init__(self, p_mother, p_father, **more):
print "Child", p_father, p_mother, more
super(Child, self).__init__(p_mother=p_mother, p_father=p_father,
**more)
Child(1, 2)
Unrecognized parameters are stashed away into the <more> dictionary.
