Need to convert an arbitrary byte-pair to an int.

I'm trying to size a jpeg file.  The file size is held in a short (2 byte
integer) at a certain offset.  Once I've found these two bytes (they're in
MSB,LSB order), I need to convert them to an integer - now I know that in C
I'd just cast a pointer to the offset to a short, and that python doesn't
cast, so how can I extract the value from a stream of bytes.  I've looked
at (I'm using 2.3b1), but can't find anything
