Have you tried using sets?
>>> import os
>>> os.listdir('/')
['lost+found', 'var', 'etc', 'media', 'cdrom', 'bin', 'boot', 'dev',
'home', 'initrd', 'lib', 'mnt', 'opt', 'proc', 'root', 'sbin', 'srv',
'sys', 'tmp', 'usr', 'initrd.img', 'vmlinuz', 'windows',
'initrd.img.old', 'vmlinuz.old']
>>> s = set(os.listdir('/'))
>>> p = set(['opt', 'mnt', 'initrd', 'home', 'tmp', 'lib', 'media',
'boot', 'usr', 'var', 'proc', 'bin', 'sys', 'initrd.img.old', 'cdrom',
'lost+found', 'sbin', 'vmlinuz.old', 'windows'])
>>> s - p
set(['dev', 'etc', 'vmlinuz', 'srv', 'root', 'initrd.img'])
