I've run into wanting to work with parallel directory structures
before, and what I generally do is something like:
for root, dirs, files in os.walk( dir1 ):
dir2_root = dir2 + root[len(dir1):]
for f in files:
dir1_path = os.path.join( root, f )
dir2_path = os.path.join( dir2_root, f )
Does this work for your needs?
