How to calculate number of some special incidences using a constrained nested for loops?

I have N number of circles with known positions and radii and there is n number of points with known positions. I want to calculate total number of orphaned points where it is understood that such points are not residing inside any one of the circles. I don't know how to write a python script to count such points given the constraint that outer for loop corresponds to the positions of the points and the inner for loop corresponds to the positions and radii of the circles. I need some help with that.

Thanks,
