It is better to call super than manually call the superclass. Calling A
directly means your class is no longer compatible with multiple
inheritance.

There are (at least) two ways to determine the type of something in Python:
type(obj)
obj.__class__
By design, they are not guaranteed to give the same result. Is there a
definitive explanation given by the docs for the difference and which you
should use under different circumstances?
