python继承和多态

目前在自学python，我通过设计两个类，然后再继承另一个的属性，但是具体的操作不清楚，求解

# 定义 Weapon 类
class Weapon:
    def __init__(self, weight, firepower, price, anti_strike):
        self.weight = weight  # 重量
        self.firepower = firepower  # 
        self.price = price  # 价格
        self.anti_strike = anti_strike  # 抗击打力

# 定义 Tank 类，继承 Weapon 类
class Tank(Weapon):
    def __init__(self, weight, firepower, price, anti_strike, oil_consumption, speed, health):
        super().__init__(weight, firepower, price, anti_strike)  # 调用父类构造函数
        self.oil_consumption = oil_consumption  # 单位里程耗油量
        self.speed = speed  # 移动速度
        self.health = health  # 健康程度

    def BeHit(self, strike_force):
        # 计算受到的损伤
        damage = strike_force / self.anti_strike
        self.health -= damage

    def ShowState(self):
        # 显示对象状态
        print("重量：", self.weight)
        print("火---力：", self.firepower)
        print("价格：", self.price)
        print("抗击打力：", self.anti_strike)
        print("单位里程耗油量：", self.oil_consumption)
        print("移动速度：", self.speed)
        print("健康程度：", self.health)

# 创建 Tank 对象
my_tank = Tank(2000, 800, 500000, 600, 10, 50, 100)

# 受到火--力为 20000 的打击
my_tank.BeHit(20000)

# 显示受--打--击后对象的状态
my_tank.ShowState()
