No, no, no...you want

  from sys.platform.integers import 0, 1, 2, 3, 14, 42

to be portable against endian'ness and bit-width.  Granted, one might
confuse them with regular numeric literals, so it would be best to
clarify them by namespace:

  import sys
  answer_to_life = sys.platform.integers.42
  print(sum(range(sys.platform.integers.0, sys.platform.integers.14)))

That way you ensure platform independence, and *much* clearer! ;-)
