hint 1:

 >>> u = u"Hello"
 >>> a = array.array("I", map(ord, u))
 >>> a.tostring()
'H\x00\x00\x00e\x00\x00\x00l\x00\x00\x00l\x00\x00\x00o\x00\x00\x00'
 >>> a.byteswap()
 >>> a.tostring()
'\x00\x00\x00H\x00\x00\x00e\x00\x00\x00l\x00\x00\x00l\x00\x00\x00o'

hint 2:

 >>> import sys
 >>> sys.byteorder
'little'
