You could write your own class mimicing a list with your desired behaviour, something like: py>class llist(object): py> def __init__(self, arg = []): py> self.__list = arg py> def __setitem__(self, key, value): py> length = len(self.__list) py> if length < key: py> for i in range(length, key +1): py> self.__list.append(None) py> self.__list[key] = value py> def __str__(self): py> return str(self.__list) py> py>x = llist() py>x[10] = 1 py>print x [None, None, None, None, None, None, None, None, None, None, 1] for other methods to add to the llist class see http://docs.python.org/ ref/sequence-types.html -- http://mail.python.org/mailman/listinfo/python-list
