Those default values are not 0 and <size-of-sequence>, you may have only experience with situations where they behave as such but that is not the same. > than arbitrary values > f(,,,,,3) > > in some arbitrary function. If you need to know these values then you will need to know them just as much when a keyword is used or when the default values are used later. Calling f(3) or f(arg5=3) Will give you no more a clue about the missing default values than calling f(,,,,,3) At least in the last call you are given a clue about missing arguments. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
