I'm in need of help to solve this Python (ver. 3.3) problem:
I have a hierarchy of classes (SubA, SubAB, SubB, ..., SubBCA,
SubC,...), each of which is inheriting from a chain of superclasses with
a common baseclass(Sup) on top. (So far, no problem)
Now, I want to create instances of the correct subclasstype as decided
by the common baseclass, like this:
i = Sup(args_allowing_the_baseclass_to_deduce_correct_subclass)
where i can be of any class except Sup itself (as decided by Sup)
Now, the problem:
How to design the __new__() and __init__() methods for the various
classes in order to achieve what I want?
(Some ten years I had the same problem (in a different context) and was
helped by asking in this group. However, the solution has disappeared.
Maybe the 2.x solution is not the same as in 3.x?)
