Why do you want to do this? You'll have to do some logic in your method body to determine how many operands you have whether you explicitly pass a list or whether you have the system break it apart into separate parameters. Fredrick Lund's solution, using an * parameter in the method definition, will produce a list that you have to pull apart in the method. Doing the same in the method call takes a single list of all of your parameters and then distributes it among the parameters in the definition. I wouldn't bother with either one. Passing a list of my real parameters as a single parameter is, in most circumstances, easier and IMO clearer. John Roth -- http://mail.python.org/mailman/listinfo/python-list
