python - 如何使用 __str__ 更改对象属性的显示方式？

Question

我希望我的玩家的筹码必须显示为 $xxx，但要将筹码保留为 int。我尝试了下面的代码，但 str 部分只是灰色的。我做错了什么？

class Player:
    def __init__(self, name, gender, taunt, aggression, hand, chips):
        self.name = name
        self.gender = gender
        self.taunt = taunt
        self.aggression = aggression
        self.hand = hand
        self.chips = chips

        def __str__(self):
            return "${0}".format(self.chips)

您需要做的是取消缩进 __str__ 函数，它将正常工作:

class Player:
    def __init__(self, name, gender, taunt, aggression, hand, chips):
        self.name = name
        self.gender = gender
        self.taunt = taunt
        self.aggression = aggression
        self.hand = hand
        self.chips = chips

    # Note the outdent of the function

    def __str__(self):
        return "${0}".format(self.chips)
