I get an error "TypeError: 'rounding' is an invalid keyword argument for this function" on my list subclass.How might I subclass list without this error? This is the code: class SeriesList(list): def __new__(cls, *args, **kwargs): series_list = list.__new__(cls, *args) series_list.rounding = kwargs.get('rounding', None) return series_list def moving_average(self, function, period=10): index = 0 window = [] ma = [] for i in self.__iter__(): i = float(i) if is_not_nan(i): window.insert(0, i) if len(window) == period: ma.append(function(window)) window.pop() else: ma.append(float('nan')) return round(ma, self.rounding) ---
I copied and ran the above. It gives me no errors. Of course all it is is a class definition. Is there more to the code? And please post the traceback so we have more information! -- Bob Gailer Chapel Hill NC 919-636-4239 _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
