Would that be like:

def hex2bytes(input, output):
     for i in range(0, len(input), 2):
         output.write(chr(int(input[i:i+2], 16)))

Well, that's like current Python.  In Python 3k I believe you would 
simply do output.write(int(input[i:i+2], 16)), since byte streams just 
contain integers.
