You need to iterate over os.walk():

for root_o, dir_o, files_o in os.walk(top):

or store the iterator first, then loop:

walker = os.walk(top)
for root_o, dir_o, files_o in walker:

The return value of the callable is a generator function, and only when you iterate over it (with a for loop or by calling next() on the iterator) does it yield the 3-value tuples.
