Yes, check the copy module. copy.copy() does a shallow copy of the parameter, copy.deepcopy() a deep copy of the parameter. For the difference between the two, check the manual. (basically, a deep copy copies the whole object tree for container objects such as lists/tuples/dicts/instances, a shallow copy copies only the topmost container) > <snip...> > but not small ones: > >>> a = 5 > >>> b = a + 0 > >>> id(a) == id(b) > > True What sense is there cloning integers/strings? Integer and string objects are immutable in Python, so why'd you want to have different IDs for an object of the same value? It's the value you're working with in a program, not the objects ID. At least it should be, if you're truly intent on working with the (pseudo-random) object-ID, something with your design is really, really broken. --- Heiko. -- http://mail.python.org/mailman/listinfo/python-list
