Extract nodal coordinates from the deformed testsubject (abaqus-python)

I am trying to make a python script to extract the nodal coordinates from the ODB file (from abaqus). So far i have come up with the code attached below (don't mind the extra information i put behind the #, sometimes it's just so i can keep track of what i'm doing)

The problem is that the coordinates i extract are those from the undeformed test subject. and i need the coordinates of the nodes from the deformed test subject. Can somebody help me with how i reach this information using python code?

from abaqus import *
from abaqusConstants import *

from odbAccess import openOdb

for ODBname in os.listdir("D:/r0333338/Documents/MP/nodal_files_genereren/OBD"): # this is where all your ODB files are located #t hier wordt ook de odb file gekozen die geopend zal worden
    SUBname = ODBname[1:3]  # My subject ID is saved in the ODB name - this helps me create the file #woerdt er hier de 3e tot6e letter van de ODBname gepakt ?
    print 'Current File: '+ODBname #voor check welke file er gebruikt wordt #t (ZIT '.odb' hier bij in ?)
    ODBnamefull = 'D:/r0333338/Documents/MP/nodal_files_genereren/OBD/'+ODBname   # Full path to the ODB file, otherwise abaqus tries to find it in default work directory
    odb = openOdb(path=ODBnamefull)  #open the ODB file

    assembly = odb.rootAssembly     #t declareren van assembly?

    session.viewports['Viewport: 1'].odbDisplay.setFrame(step=0, frame=1)
    numNodes = 0   #t num nodes op nul zetten 
    f = open("D:/r0333338/Documents/MP/nodal_files_genereren/ODBoutput/nodal.txt", "w") #indien het bestand al bestaat moet er "a" staan ipv "w"
    for name, instance in assembly.instances.items(): #t 'name' is naam van elke part van in de assembly ?
        n = len(instance.nodes) #t tellen van hoeveelheid nodes
        print 'Number of nodes of instance %s: %d' % (name, n) #moet niet in de file staan, kan eigenlijk weggelaten worden. (maar is een goede check?)
        numNodes = numNodes + n #tellen van totaal aantal nodes (globaal over alle parts) maar is eigenlijk niet nodig?
        f.write( "*Part, name=Part-1" + "\n")#moet erin staan volgens de MatchId regels
        f.write( "*Nodes" + "\n")            #moet erin staan volgens de MatchId regels

        if instance.embeddedSpace == THREE_D: #indien het 3D is
            print ' X Y Z' #moet niet in de file staan, maar is een goede check om te zien waar we zitten
            for node in instance.nodes:
                #print node #printen van node
                f.write( str(node.label) + ";" ) #schrijven van nodenummer
                f.write(str(node.coordinates[0]) + ";" + str(node.coordinates[1]) + ";" + str(node.coordinates[2]) + "\n") #schrijven van coordinaten [X;Y;Z] en enter
        else: #indien het 2D is
            print ' X Y' ';0' #moet niet in de file staan, maar is een goede check om te zien waar we zitten
            for node in instance.nodes:
                #print node #printen van node
                f.write( str(node.label) + ";" )
                f.write(str(node.coordinates[0]) + ";" + str(node.coordinates[1]) + ";" + str(node.coordinates[2]) + "\n") #schrijven van coordinaten [X;Y;Z] en enter
        f.write( "*End Part" ) #moet erin staan volgens de MatchId regels
    f.close()

get the displacement field:

 u=odb.steps['Step-1'].frames[-1].fieldOutputs['U']

then u.values is a list of all nodal values:

 u.values[i].data -> array of (ux,uy,uz)
 u.values[i].nodeLabel  -> node label

then you grab the original position like this:

 instance.getNodeFromLabel(u.values[i].nodeLabel).coordinates

You can also directly get the deformed coordinate as a field output, but you need to request COORD output when you run the analysis.
