That is more or less the text from the "Quick Python Book". What am I
doing wrong?
If you're quite new to Python I would advise to drop super and use an
explicit call, sounds lame but my guess is that many people do that,
'cause explicit >> implicit. Super is meant to solve some issues about
multi inheritance, especially diamond diagram inheritance. It has no
benefit for single inheritance.
I'm pretty sure someone will state that understanding super is pretty
much easy once you've read the documenation but anticipating all the
underlying concepts may be tricky. The only situation where super is
absolutely required is when the inheritance diagram is built dynamically
during execution.
Otherwise, I would say "Have the nuts to explicit which base class
method you want to call" (easy for single inheritance though :) )
class C(P):
def __init__(self):
P.__init__(self)
