I am trying to label a node by its coordinates, see the code below. I'm not sure why it does not work?

#--------------------------- begin code -----------------------------------

x1 = 4.0
y1 = 0.75
z1 = 0.12

mdb.models['Model-1'].rootAssembly.Set(name='nodeLabel', nodes = mdb.models['Model-1'].parts['Plate-1'].nodes.getClosest(coordinate = (x1, y1, z1)))

#--------------------------- end code -----------------------------------
