As George hinted, I went a bit over the top with my itertools example. Here is a translation into static lists (mostly): from itertools import izip from random import choice first = ["X", "Y", "Z"] second = ["A", "B", "C"] third = [1.1, 2.2, 3.3, 4.4] x, y, z = first a, b, c = second def random_floats(sample): while 1: yield choice(sample) columns = [ range(180), [x]*60 + [y]*60 + [z]*60, ([a]*13 + [b]*14 + [c]*33) * 3] + [random_floats(third)]*28 for row in izip(*columns): print row Of course nested loops will work, too. Use whatever you find easiest to maintain. Peter -- http://mail.python.org/mailman/listinfo/python-list
