If you only want to copy up to level-2, then you can do something like: cloned = [subl[:] for subl in somelist] Or sometimes safer: cloned = [list(subl) for subl in somelist] If you want to go all the way down, you can use the deepcopy function of the copy module. In many situations the level-2 copy may be enough, and it can be faster. Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
