Um, I'm fairly sure this line is not doing what you think it is doing! self is just a local variable. When __init__ is called, self is bound to the MyFoo instance. But when you do 'self = inlist[:]', you just rebind it to a copy of inlist. You aren't changing self.. > >>> me = MyFoo(range(10)) > >>> type(me) > <class '__main__.MyFoo'> > > >>> type(me[0:3]) > <type 'list'> Have you tried implementing __getitem__ and __setitem__ for slice objects?
