problem with struct module

I'm trying to use the unpack method in the struct module to parse a
binary file without success. I have a binary file with records that
include many fields for a total length of 1970. Few days ago I was
suggested by the list to use the struct module to parse it using the
following code in the hypothesis that for each records I have just two

import struct

while s:
    print 'read:', s
    print 'unpack', d1

Probably I was not even able to explain my problem since it seem that
this code is not able to read the file. Can anybody help me, maybe
asking for other infos they need? Also just suggest me a place where I
can find examples of using struc.unpack would be very helpful.
