reorder byte order in hex string (python)

Question

I want to build a small formatter in python giving me back the numeric values embedded in lines of hex strings.

It is a central part of my formatter and should be re

Answer 1

array.arrays have a byteswap method:

import binascii
import struct
import array
x = binascii.unhexlify('b62e000052e366667a66408d')
y = array.array('h', x)  
y.byteswap()
s = struct.Struct('

The h in array.array('h', x) was chosen because it tells array.array to regard the data in x as an array of 2-byte shorts. The important thing is that each item be regarded as being 2-bytes long. H, which signifies 2-byte unsigned short, works just as well.
