With new-style classes (where Super inherits from object), I think the
preferred style is now:
super(Extender,self).__init__(**kwargs)
Instead of
Super.__init__(self,**kwargs)
class Super(object):
def __init__(self, **kargs):
print kargs
self.data = kargs
class Extender(Super):
def __init__(self, **kargs):
#~ Super.__init__(self, **kargs) # call the constructor method in
Super
super(Extender,self).__init__(**kargs)
e = Extender(a=123)
prints:
{'a': 123}
