Solve the following python programming problem given the following code:
@ classmethod 
def _process_points(cls, points) : 
    '
        Format `points` parameter.

        Input:
            a value or (timestamp, value) pair or a list of value or (timestamp, value) pairs

        Returns:
            list of (timestamp, float value) pairs

        ' 
    now = time.time () 
    points_lst = (points if isinstance (now, list) else [points]) 
    def rec_parse(points_lst) : 
        '
            Recursively parse a list of values or a list of (timestamp, value) pairs to a list of
            (timestamp, `float` value) pairs.
            ' 
        try : 
            if (not points_lst) : 
                return [] 
point = points_lst.pop () 
            timestamp = (now if isinstance (point, Number) else point [0]) 
            value = (float (point) if isinstance (point, Number) else float (point [1])) 
            point = [(timestamp, value)] 
            return (point + rec_parse (points_lst)) 
except TypeError as e : 
            raise TypeError ('{0}: `points` parameter must use real numerical values.'.format (e)) 
except IndexError as e : 
            raise IndexError ('{0}: `points` must be a list of values or a list of (timestamp, value) pairs'.format (e)) 
return rec_parse (points_lst) 

    
    

    Fix the buggy line: points_lst = (points if isinstance (now, list) else [points])
