If your program deals with 4-element tuples then although you *could* 
use *stats in your calls to pass each element of the tuple as a single 
argument, that's not really necessary. A way to write the 
initializations you want without using indexing is:

class Character(object):

      def __init__(self, name, stats):
          self.name = name
          self.strength, self.dexterity, \
          self.intelligence, self.luck = stats
