Hi!
You can create struct in python with pack. See an example in the
nfsapp python version (a script you put on your S60 phone or other
which work with p3nfs (http://www.koeniglich.de/p3nfs.html)) :
http://amalfi.dis.unina.it/~foggia/nfsapp.py
Here is the example:

from struct import pack, unpack
msg = pack('<HBBLL', subdirs, flags, pad, size, mtime)
< means little-endian
H:unsigned short;
B:unsigned byte;
L:unsigned long;

for more information:
import struct
help(struct)

I hope it will be useful to you.
