If the result is to be a 'bytes' instance there are various ways. Here is one approach:

>>> a = b'\x01\x02'
>>> b = b'\x03\x10'
>>> int.to_bytes(int.from_bytes(a, 'little') ^ int.from_bytes(b, 'little'), 2, 'little')
b'\x02\x12'

Or (may be more efficient for large objects):

>>> a = b'\x01\x02'
>>> b = b'\x03\x10'
>>> bytes(map(lambda x, y: x^y, a, b))
b'\x02\x12'
>>>
