在Python中移动目录结构的方法

#Moving up/down dir structure
print os.listdir('.') # current level
print os.listdir('..') # one level up
print os.listdir('../..') # two levels up
 
# more complex example:
# This will walk the file system beginning in the directory the script is run from. It 
# deletes the empty directories at each level
 
for root, dirs, files in os.walk(os.getcwd()):
  for name in dirs:
    try:
      os.rmdir(os.path.join(root, name))
    except WindowsError:
      print 'Skipping', os.path.join(root, name)
