It would indeed be useful to have that be available in Python.
There is a much simpler way:
from Carbon import File File.FSRef('/tmp/foo').as_pathname() '/private/tmp/Foo'
Note that this is much slower compared to os.path.exists.
This won't work in py3k; the Carbon modules were removed in 3.0. A simpler alternative would probably be the F_GETPATH fcntl. An example: Python 3.1.2 (r312:79147, Jul 11 2010, 18:21:56) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information.
from fcntl import fcntl from os.path import basename, exists from os import remove
F_GETPATH = 50
if exists('/tmp/å'): ... remove('/tmp/å') ... open('/tmp/å', 'w').close() f = open(b'/tmp/A\xcc\x8a')
a = f.name b = fcntl(f, F_GETPATH, b'\0' * 1024).rstrip(b'\0')
a, b (b'/tmp/A\xcc\x8a', b'/private/tmp/\xc3\xa5') a.decode('utf-8'), b.decode('utf-8') ('/tmp/Å', '/private/tmp/å')
