如何在一个方法中增加一个值（num）并减少在Python类中定义的另一个值？

Question

我正在用python做游戏，我需要创建一种方法来增加/减少我在类中定义的值。 该方法收到一个数字，我必须修改另一个数字。 这是我的代码：

class Ant:
    def __init__(self, name, steps, health, alcohol, state):
        self.name = name
        self.steps = []
        self.health = 100
        self.alcohol = 0
        self.state = state

我需要修改健康状况。请帮助我

Answer 1

使用单个参数定义方法并修改self.health ：

class Ant:
    def __init__(self, name, steps, health, alcohol, state):
        self.name = name
        self.steps = []
        self.health = 100
        self.alcohol = 0
        self.state = state

    def add_health(self, value):
        self.health += value

    # bonus
    def drink(self, value):
        self.alcohol += value
        self.health -= value

Answer 2

您可以创建一些从Ant的健康中减去的功能。 例如：

class Ant:
    def __init__(self, name, steps, health, alcohol, state):
        self.name = name
        self.steps = []
        self.health = 100
        self.alcohol = 0
        self.state = state

    def damage(self, amount):
        self.health -= amount
