When creating a class which contains elements that are lists, the lists for different instances of the class are not independent. Calling self.mylist.append(3) inside a class method will update the mylist variable for *all* instances of the class, not just the current instance. Attached is a script which demonstrates this behavior. |

Sorry, that is correct behavior for class variables. To get your intended effect (independent lists) do the list instantiation inside the __init__ method. |
