title: Is it possible for two singleton subclasses to use their own instance of superclass in Python?
body: <p>I have two singleton subclasses A and B, which data needs to be maintained separately. When one subclass A make use of superclass, some of the informations will be stored in list and dict in superclass. But when I try to invoke superclass from another subclass B the informations that are stored by subclass A causing issues. </p>
  
  <p>Is it possible to have seperate instance of superclass for both A and B subclasses.</p>
  
  <p>(I used self for superclass members)</p>
