    For extracting displacements from Modal analysis, please find below an example script, which prints ux, uy and uz for node 310 for Mode 6. This can be further expanded to loop over each mode and export displacements for all nodes.

    import mech_dpf
import Ans.DataProcessing as dpf

#Extract Modal analysis system
analysis = Model.Analyses[0]
ds = dpf.DataSources(analysis.ResultFileName)

#mesh scoping
my_scoping = dpf.Scoping()
my_scoping.Location="Nodal"
my_scoping.Ids = [310]

#Time list
timelist = dpf.operators.metadata.time_freq_provider(data_sources=ds).outputs.gettime_freq_support().TimeFreqs.Data
time_index_list = range(1,timelist.Count+1,1)

disp_fc = dpf.operators.result.displacement(time_scoping=time_index_list, data_sources=ds, mesh_scoping = my_scoping).outputs.getfields_container()

#Print ux, uy and uz for Mode 6 for Node 310
print(disp_fc[5].Data)
