Copy a file, preserving all directories, with a horrible mixture of python shutil and os.system('mkdir -p')

copy_with_dirs.py

#!/usr/bin/env python

# Usage: copy_with_dirs.py <file> [file] [...]
#        OR ... | xargs -d '\n' /tmp/copy_with_dirs.py

import shutil
import urllib
import sys
import os

for filename in sys.argv[2:]:
    filename = urllib.unquote(filename)
    print filename

    new_filename = filename.replace(
        '/home/jp/Music/library/',
        '/media/jp/CHEWINGGUM/Kodi/'
    )

    os.system('mkdir -p "%s"' % os.path.dirname(new_filename))
    shutil.copyfile(filename, new_filename)
