i don't know how to call methods of super classes when using multiple
inheritance. I've looked on the net but with no result :(
class a(object):
def foo(self):
print "a"
class b(object):
def foo(self):
print "a"
class c(a,b)
def foo(self):
super( a).foo()
if I only use the super() construct it seems not to call B
class A(object):
def foo(self):
print "a"
class B(object):
def foo(self):
print "b"
class C(A,B):
def foo(self):
print "c"
super(C,self).foo()
c
how nice! is this due to a linearization taking place of A and B when
compiling C ? is this a 'feature' of the language or its actual
semantics to behave like this?

Hello. I need to be able to control how objects are created. Sometimes
when creating an object, i want to reuse another object instead. I've
searched for factory method implementations and singleton
implementations. They were too much of a hack!
My first attempt of doing this was to play around wi

yes i know of that difference... but one cannot easily override a class
method in a supclass.. as calling super then make the cls variable
point to the super class class rather than th
