如何在一個方法中增加一個值（num）並減少在Python類中定義的另一個值？

Question

我正在用python做游戲，我需要創建一種方法來增加/減少我在類中定義的值。 該方法收到一個數字，我必須修改另一個數字。 這是我的代碼：

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

我需要修改健康狀況。請幫助我

Answer 1

使用單個參數定義方法並修改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

您可以創建一些從Ant的健康中減去的功能。 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
