Python Special variable return from my class [closed]

  oop, python

python learner here.
I have 2 classes, Sphere and Frustum. I create the instances from these 2 class and return from a subprocedure.
When it is returned, it is marked as Special Variables.
The problem is in my main program, I need to check to which class the return result belongs to, but now I cannot. Can anyone help me how to convert it to it primitive class. thank you
