Depends what, exactly, you want your script to do :)

The simplest way to get an ad-hoc look at what permissions are applied to
a file is:

<code>
import os, sys
from winsys import fs

#
# Just using sys.executable as a file I know will exist;
# obviously you put your own file name in there...
#
fs.file (sys.executable).security ().dump ()

</code>

To get that in the more compact but more esoteric MS SDDL format:

<code>
import os, sys
from winsys import fs

print (fs.file (sys.executable).security ())

</code>

To decode the permission bit-strings to vaguely meaningful
names:

<code>
import os, sys
from winsys import fs

dacl = fs.file (sys.executable).security ().dacl
for permission in dacl:
   print (d.trustee, " (Inherited )" if d.inherited else "")
   for name in fs.FILE_ACCESS.names_from_value (d.access):
     print ("  ", name)

</code>
