Most of that stuff doesn't end in code meant to do anything important. It's more like gymnastics that helps you keep your mind in shape. Or so I would hope. >>> items = [1, 2, 3] >>> result = 3*len(items)*[None] >>> result[::3] = result[1::3] = result[2::3] = items >>> result [1, 1, 1, 2, 2, 2, 3, 3, 3] >>> from itertools import * >>> list(chain.from_iterable(starmap(repeat, izip(items, repeat(3))))) [1, 1, 1, 2, 2, 2, 3, 3, 3] ;) Peter -- http://mail.python.org/mailman/listinfo/python-list
