Question

How do I limit os.walk to only return files in the directory I provide it?

def _dir_list(self, dir_name, whitelist):     outputList = []     for root, dirs, files in os.walk(dir_name):         for f in files:             if os.path.splitext(f)[1] in whitelist:                 outputList.append(os.path.join(root, f))             else:                 self._email_to_('ignore')     return outputList

Use the walklevel function.

import os  def walklevel(some_dir, level=1):     some_dir = some_dir.rstrip(os.path.sep)     assert os.path.isdir(some_dir)     num_sep = some_dir.count(os.path.sep)     for root, dirs, files in os.walk(some_dir):         yield root, dirs, files         num_sep_this = root.count(os.path.sep)         if num_sep + level <= num_sep_this:             del dirs[:] 

It works just like os.walk, but you can pass it a level parameter that indicates how deep the recursion will go.
