Python extending with – using super() Python 3 vs Python 2

super() (without arguments) was introduced in Python 3 (along with __class__):

super() -> same as super(__class__, self)

so that would be the Python 2 equivalent for new-style classes:

super(CurrentClass, self)

for old-style classes you can always use:

 class Classname(OldStyleParent):
    def __init__(self, *args, **kwargs):
        OldStyleParent.__init__(self, *args, **kwargs)
