Nornal Vectors for Planes

I am trying to export some data from simple geometry in a Blender scene to an outside program.

I have multiple groups of planes that make up more complex objects. I would like to print out the normal vectors for each plane within each group. Is there a function or way to do this within python scripting??

If anyone knows, can you please help me out with this??

Thanks!!!
