By way of example, here is a ghpython sample, (Rhino V6), the replicates the Native Brep Topology Component.

import Rhino
from ghpythonlib import treehelpers as th

FF1 = []
FE1 = []
EF1 = []

for f in x.Faces:
    FF1.append(f.AdjacentFaces())
    FE1.append(f.AdjacentEdges())
    
for e1 in x.Edges:
    EF1.append(e1.AdjacentFaces())
    
FF = th.list_to_tree(FF1, True)
FE = th.list_to_tree(FE1, True)
EF = th.list_to_tree(EF1, True)

The tree helpers are specific to GH, to deal with the whole nested array/list/data tree issues. They are awesome.
