#select some Draft Points-non Draft Vertexes won't work with this particular method:
selection = Gui.Selection.getSelection()

for p in selection:
    print p.X,",",p.Y,",",p.Z


#for non Draft workbench points (ie Vertexes selected at line end points), that you pick on the screen:
selection = Gui.Selection.getSelectionEx()[0].SubObjects
for v in selection:
    print v.X,",",v.Y,",",v.Z

#for end points of Draft rectangle for an example:

rect = Gui.Selection.getSelection()[0]
