I think you are misunderstanding how del and mutable sequences work. In your code snippet, the del unbinds the name "root_dir" but it does not alter the dirnames list object returned by os.path. Try replacing "del root_dir" with "del root_dir[:]" or "root_dir.clear()". http://docs.python.org/3/reference/simple_stmts.html#the-del-statement http://docs.python.org/3/library/stdtypes.html#mutable-sequence-types
