第六周练习 part1 --- 类

　　

# 类
class Role:
    def __init__(self, name, character, weapon, skills=10, life_value=10000, money=30000, level=99):
        # 构造函数，在实例化时做一些类的初始化工作
        self.name = name  # [[实例变量]]（静态属性）【变量】，作用域是实例本身
        self.character = character
        self.weapon = weapon
        self.life_value = life_value  # 私有属性——前面加两个杠，就不能在类的外部直接访问、更改了，类内部的方法仍可以访问
        self.money = money
        self.level = level
        self.skills = skills

    def __del__(self):
        # 析构函数，做收尾工作
        print("%s Completely Dead" % self.name)

class Villan(Role):
    def kill(self):
        print("I am Thanos")

class Avenger(Role):
    A = "Infinity War"  # [[类变量]]
    '''类变量与实例变量
    类变量存储实例共有的属性，实例变量存储各自特有的属性
    所以若实例变量中出现了和类变量同名的变量，自然是优先访问实例变量
    但并不通过将其设置为默认参数来给实例添加属性，因为类变量只需要一份存储空间
    而实例变量则每次实例化都会占用一次存储空间'''

    def show_info(self):
        # 类的方法、功能（动态属性）【方法】
        print('''Name: %s\nCharacter: %s\nWeapon: %s\nLife_value: %s\nMoney: %s\nSkills: %s\nLevel: %s'''
              % (self.name, self.character, self.weapon, self.life_value, self.money, self.skills, self.level))

    def aim_at(self, name):
        print("Aim at %s now" %name)

    def shoot(self):
        self.money += 10
        print("Target got shoot")
        print("%s earned 10 bucks and now he has %s bucks" % (self.name, self.money))

    def get_shoot(self):
        self.life_value -= 10
        print("%s got shoot and his current life value is %s" %(self.name, self.life_value))

    def gun(self, new_weapon):
        self.weapon = new_weapon
        self.money -= 100
        print("%s costs you 100 bucks and now you have %s bucks left" %(new_weapon, self.money))

    def __privatefunc(self):  # 私有方法，也是在类外部不能调用，只能在内部由别的方法调用
        pass

# 实例化过程，得到 Role 的实例
# c1 = Avenger('Lief', 'GoodMan', '399式')
