Be warned though that if you try this with a non-existent or otherwise 
inaccessible directory you will get an exception: 

$ sudo mkdir forbidden
$ sudo chmod a-r forbidden
$ python3 -c 'import os; next(os.walk("forbidden"))'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
StopIteration
