super() does not work with classic classes:
>>> class Classic: pass
...
>>> class A(Classic):
... def __init__(self):
... super(A, self).__init__()
...
>>> A()
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "<stdin>", line 3, in __init__
TypeError: super() argument 1 must be type, not classobj
whereas:
>>> class A(object):
... def __init__(self):
... super(A, self).__init__()
...
>>> A()
<__main__.A object at 0x402ac02c>
Invoking
def __init__(self, *argv):
PRI.BasicBatch.__init__(self, *argv)
explicitly instead works as well unless you need cooperative methods which
are only possible with newstyle classes.
