Question

Here is my class:

Answer 1

Your class already inherits from other class as you declared, class Iter (object), Iter extends object. What do you mean "acts like another class I choose...".

Have you tried class Iter(<otherClass>) where <otherClass> is the other class of your choice?

Sorry if I misunderstood you.

Answer 2

I must admit that what you're doing is something pretty advanced, and from the external resources (read:stackoverflow:) there's no easy way in achieving your goal.

I'm afraid I'm gonna have to leave you with these links I've read, not being ignorant, but I realize that's just as far as I can go. So here they are, bear me if you've already visited them:

Best of luck,

Answer 3

It was inherits from object to avoid infinite loop since I had redefine __getattribute__. I've done this to detect instance.next but I've just change it (now it is instance.next()).
As you've probably see, the class can contains a list or a tuple. So what I want is when I use the instance like a = instance + 2, instance acts like instance.list[instance.index]. I know when I do it, it calls the special method for addition, in I can write :
return self[instance.index] + other
But I would have to write all the special methods only to redirect...

Answer 4

Actualy I need to create a metaclass to intercept the special method calls but I'll have to study how it work.
