Recursion is your friend. Write a function to unpack one "sublist" and call itself again with the new list. For instance, something like: def unpack(pattern): # Find the first subpattern to replace # [...] results = [] for number in subpattern: results.append(pattern.replace(subpattern, number)) return results Calling unpack([1,2,3,[5,6],[7,8,9]]) would look cause it to call unpack([1,2,3,5,[7,8,9]]) and unpack([1,2,3,6,[7,8,9]]), compile the results, and return them. -- Kirk Strauser The Day Companies -- http://mail.python.org/mailman/listinfo/python-list
