This shows how valuable it is to post your expected results with your code. The way most experienced python programmers might do this is with list comprehension: res = [[1, i] for i in xrange(1,7)] For newer programmers, this might make more sense: res = [] for i in xrange(1,7): res.append([1,i]) James -- James Stroud UCLA-DOE Institute for Genomics and Proteomics Box 951570 Los Angeles, CA 90095 http://www.jamesstroud.com/ -- http://mail.python.org/mailman/listinfo/python-list
