oh sorry for the confusion, doTest() didn't mean anything it was just
place holder for do some code here.
for x1, x2 in zip( vertList1[:-1:2], vertList1[1::2] ):
for y1, y2 in zip( vertList2[:-1:2], vertList2[1::2] ):
if y1 == x2 and y2 == x1:
print 'match found', x2, x1
break
Generally it is not very efficient to nest for loops like that. It
gets exponential slower as you add more items to the list.
In the past when I've need to 'walk' my way around mesh I've used
selection commands.
1. Start with a face
2. Select the first 2 verts (or edge) of the face
3. Convert the selection to faces
4. For each face (that is not our starting face) get the verts used
by the face
5. When you find a face that uses both of our original verts you have
found the neighbour face.
This should be faster because you don't have to search through all of
the verts every time.
