Abaqus - How to obtain the coordinates of node sets using Python secondary development

Take this simple 2D contact project as an example, I chose the surface of the one part on the bottom to be a node set. It took 4 frames to complete the calculation, and I want to export the process of the coordinate changes, to see how it deforms. How can I do that using Python? 

I did a little research online, but all none of them focuses on node set, only the whole model or specific nodes.

my_odb = openOdb(r"D:\SIMULIA2020\script_learning\case3\ODBandOtherRealtingFiles\Job-1.odb") 

node_Labels = (55,56,57,58) 

node_set = my_odb.rootAssembly.instances['PART-1-1'].NodeSetFromNodeLabels(name='set_for_datas',nodeLabels=node_Labels)

local_dis_values = dis_field.getSubset(region=node_set)

Can anybody help me, thanks a lot!!!
