  I think I'm making this unnecessarily complicated. I had used
  something like:

  from spam import TestAddresses ## just for grins

  Which is something that I almost never do in practice.

  Also, you pointed out the UC naming convention, which I was
  unacquainted with, being self-employed, self-taught and a one-man
  crew who doesn't spend as much time as he should reading PEPs.

  I'm going to go for the predicate test as second argument to
  getmembers with something like:
def isdata(self,obj,name):
    """Check if an object is of a type that probably means it's data."""
    return (not (inspect.ismodule(obj) or inspect.isclass(obj) or
                inspect.isroutine(obj) or inspect.isframe(obj) or
                inspect.istraceback(obj) or inspect.iscode(obj)))
                and name.issupper()
## Untested code
