Place empty while in Edit Mode

Sometimes we need to place a marker (Empty) at a given point on our mesh. I use this often to define a pivot point. But manually hopping in and out of edit mode to add an Empty soon becomes lame. This is my solution. Run this in edit mode, select as many verts as you wish.

	# be in edit mode to run this code
	import bpy
	from mathutils import Vector
	myob = bpy.context.active_object
	bpy.ops.object.mode_set(mode = 'OBJECT')
	# collect selected verts
	selected_idx = [i.index for i in myob.data.vertices if i.select]
	original_object = myob.name
	for v_index in selected_idx:
	# get local coordinate, turn into word coordinate
	vert_coordinate = myob.data.vertices[v_index].co
	vert_coordinate = myob.matrix_world * vert_coordinate
	# unselect all
	for item in bpy.context.selectable_objects:
	item.select = False
	# this deals with adding the empty
	bpy.ops.object.add(type='EMPTY', location=vert_coordinate)
	mt = bpy.context.active_object
	mt.location = vert_coordinate
	mt.empty_draw_size = mt.empty_draw_size / 4
	bpy.ops.object.select_all(action='TOGGLE')
	bpy.ops.object.select_all(action='DESELECT')
	# set original object to active, selects it, place back into editmode
	bpy.context.scene.objects.active = myob
	myob.select = True
	bpy.ops.object.mode_set(mode = 'EDIT')
