Thanks for the help! Using the "class name (object)" syntax fixed my problem.
Usually, I don't need properties, but in the case of a dependent attribute, I used a set method of a property to update that dependent attribute. I have a stopwatch class with a time limit property. When the time limit is changed, the dependent attribute, remaining time, should also change. I am having to unteach myself some of the defensive programming techniques in C++, such as using name mangling to ensure privacy, when privacy is not the most important criterion. For prototyping, starting public and going "private" later is more efficient when refactoring. And since properties have the same access signature as a public member, it can be done without changes to the client. -- Ethan -- http://mail.python.org/mailman/listinfo/python-list
