You could do the argument checking yourself, after extracting them. But (without knowing what you're actually up to here) – are you sure the above is a good user interface? Did you consider splitting the function into two, one that takes arguments and one that takes none? Stefan -- https://mail.python.org/mailman/listinfo/python-list
