pythonocc identify holes (and it dimension) in surface

Question

I have an object, and I am checking it's faces (for exmaple the attached object). First I have checked if each of it's faces is a plane/cylinder or Bspline surface. Now, I need to check if the face has holes in it (it can have cylindrical or square of any other hole) and to get the dimensions of this hole.

With what functions in pythonocc library , I can detect that? please advice

see attached image as an example enter image description here
