No.

Allow me to add to my previous question that certainly the superclass
methods can be called explicitly without resorting to super(), e.g.:
class C(A, B):
def __init__(self):
A.__init__(self)
B.__init__(self)
My question is really whether there is any way of get
In Python 3, how should super() be used to invoke a method defined in C that
overrides its two superclasses A and B, in particular __init__?
class A:

print('A')
class B:

print('B')
