How does it know when to skip the end value (i.e. act as for the rest of Python) and when to include it? Or did you mean: Table(f,[1,3,1],[2,7,2]) returns [[f(1,2),f(1,4),f(1,6)],[f(2,2),f(2,4),f(2,6)]] Wouldn't it be more sensible just to take the iterators directly as arguments, so for this example you would do: Table(f, range(1,3), range(2,7,2)) That way you have more flexibility (e.g. to do out-of-order ranges such as [1,3,2,0,4]), and the code for Table is much simpler since it just has to manipulate the lists it was given. -- http://mail.python.org/mailman/listinfo/python-list
