Move the active object (EMPTY) to the 3D cursor

The title says it all.
I have an empty that I want to move to the 3D cursor while maintaining its orientation.
I’m sure this is simple but I’m new to Python.

hi, you can move your ‘empty’ object like this:
empty.location = bpy.context.scene.cursor_location

or even simpler, add empty at cursor position this way:
bpy.ops.object.add(type=‘EMPTY’, view_align=True, location=bpy.context.scene.cursor_location)

Thank you very much! That did it perfectly.
I’m learning Python and had an idea to make working on skewed parts of the mesh easier.
It’s just a way to fix orientations so you can return to them and have a sort-of Top, Bottom, Right, Left views you can flip thru like the number pad does in world space.
Like on hands. They are a pain to align bones and tell the role is correct when you can’t get the proper views of the hand and thumb.
Here is a snapshot of what I’m playing with. Not much so far.
