Help - AppleScript to delete empty folders

Question

I have been trying to create an AppleScript that will let me clean directories of empty folders. I have scoured the web and developed the following script. It doesn't work. I have a simpler script but it requires that I enter my admin password everytime that a folder is identified to delete. I'm trying to develop something that only requires me to enter the admin password once. Can someone help me identify the problem with this script?
on killEmpty(fol)
  tell application "Finder"
  repeat with f in (get fol's folders)
  my killEmpty(f)
  end repeat
  if (count items of fol) is 0 then do shell script "rmdir" with administrator privileges
  end tell
end killEmpty
tell application "Finder"
  repeat with f in (get folders of window 1)
  my killEmpty(f)
  end repeat
endtell

Hi,
If you need an administrator's password, use a command in a do shell script to find and delete all empty folders, like this script:
tell application "Finder" to set tDir to quoted form of POSIX path of the ((target of Finder window 1) as string)
set pScript to quoted form of "from os import walk; from sys import argv; from shutil import rmtree; import glob
for dirpath, _, _ in walk(argv[1], topdown=False):
    if not (glob.glob(dirpath + '/*')): rmtree(dirpath)"
do shell script "/usr/bin/python -c " & pScript & " " & tDir with administrator privileges
