That's what I was looking for.  Although I couldn't get the below to
work, I went with a different mod of the original you gave:

    def get_props_as_dict(self):
        d = dict()
        for entry in dir(self.__class__):
            if isinstance(getattr(self.__class__, entry), property):
                d[entry] = getattr(self, entry)
        return d

OK, so will a variation on my last recipe work? This looks for property
attributes of the class and gets the corresponding property on the
  def getprops_as_dict(self):
    return dict(pname, getattr(self, pname) 
      for pname in dir(self.__class__) 
        if isinstance(getattr(self.__class__, pname), property))
