Thank you for the replies. Looking at the replies I am wondering which solution is more scalable. At the moment it is only 2 nested lists but what about 5, 10, 20 or more?
Should I start looking into numpy to handle this or will list comprehension >>> [ [ x + y for x, y in zip(x,y) ] for x, y in zip(a,b) ] Be sufficient ? Thanks Sayth -- https://mail.python.org/mailman/listinfo/python-list
