Python类和替换函数？

假设我有一个包含player/score的namedtuple，如果我要替换其中任何一个函数，我会：

randomState = collections.namedtuple('randomState', ['player', 'score'])

如何创建一个类，该类的函数基本上类似于namedtuple，并且能够手动替换任一player/score

def random(state):
    return state._replace(score='123')

我不确定我在这里是否讲得通，但如果有人理解我的问题，我将非常感谢你的反馈。谢谢

如果我答对了你的问题，你需要一个函数，根据分数的值为它赋值。 这就是你要找的吗

class Random:
    def abc(self, score):
        if self.score == '123':
            ###had it were a namedtuple, I would use the replace function here, but classes don't allow me to do that so how would I replace 'score' manually? 

例如：

# recommended to use object as ancestor
class randomState(object):
    def __init__(self, player, score):
        self.player = player
        self.score = score

    def random(self, opt_arg1, opt_arg2):
        # you may want to customize what you compare score to
        if self.score == opt_arg1:
            # you may also want to customize what it replaces score with
            self.score = opt_arg2

天啊。非常感谢你。真不敢相信我居然没想到这个。

my_state = randomState('David', '100')
new_state = my_state.random('100', '200')
