piping out binaries properly

[Andy Leszczynski]

I have got following program:

import sys
import binascii
from string import *
sys.stdout.write(binascii.unhexlify("41410A4141"))


when I run under Unix I got:

$ python u.py > u.bin
$ od -t x1 u.bin
0000000 41 41 0a 41 41

and under Windows/Cygwin following:

$ python u.py > u.bin
$ od -t x1 u.bin
0000000 41 41 0d 0a 41 41
0000006


The question is how can I pipe out binary content properly and platform
independently?
