    This has been wrecking my head for the last hour :)

    I'm trying to read in numerical data from a binary file (lets call it blah) using:
    blah.read(3)

    The contents of the file:
ff 41 ff

The string i get back from read:
'\xffA\xff'   (converts the 0x41 into ascii character A)

What i want:
'\xff\x41\xff'

    So is there any way of preventing python from converting bytes to ascii in the output string?

    Data from a file is always a String. You need to look at the ``struct'' module and at the pack/unpack functions.

    Regards,
