Help reading binary data from files

[jeff]

I am stumped trying to read binary data from simple files.  Here is a
code snippet, where I am trying to simply print little-endian encoded
data from files in a directory.

    for name in os.listdir(DOWNLOAD_DIR):
                filename =  s.path.join(DOWNLOAD_DIR, name)
                if os.path.isfile(filename):
                        f = open(filename, 'rb')
                        while True:
                                ele = unpack('<h', f.read(2))[0]
                                print ele


When the code runs, 0 is always the data printed, but the data files
are not all zero.

Any quick tips?

thanks
