# -*- coding: utf-8 -*-

import os

def del_dir_tree(path):
 ''' 递归删除目录及其子目录,　子文件'''
 if os.path.isfile(path):
  try:
   os.remove(path)
  except Exception, e:
   #pass
   print e
 elif os.path.isdir(path):
  for item in os.listdir(path):
   itempath = os.path.join(path, item)
   del_dir_tree(itempath)
  try:
   os.rmdir(path) # 删除空目录
  except Exception, e:
   #pass
   print e

if __name__ == '__main__':

 dirname = '/home/xx/log'
 del_dir_tree(dirname)
