By the way, any reason why hex output represents negative number with a
negative sign (instead of the more usual 2s-complement representation)?
It's not too difficult to normalize by hand (e.g. add 2**32 if you know
the number is a 32-bit one) but it always irks me that Python doesn't
do it by default. I cannot think of a situation where the "sign" is
relevant when printing a hex number: hex is about the raw binary
representation of the number.
