The problem is the structure of your program. The myset module is

Yes, this is the problem. Each module imports the other.
Therefore you get two distinct MySet classes, and consequently two
distinct MySet.__instance class attributes.
Are you sure? This goes against my understanding: that 'import foo'
will not re-import a module that's already been imported, but will
instead simply return the existing module.
So, I think if one evaluated 'myset is __main__', you'd find they are
exactly the same module under different names; and therefore that
there is only *one* instance of 'MySet', again under two names.
You can see that they're distinct by checking the addresses (the
instances in the OP also have different addresses). Besides, __main__
isn't imported normally.
