处理一个类的多个对象

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def greet(self):
        print(f"Hello, my name is {self.name} and I am {self.age} years old.")

# 创建多个Person对象
person1 = Person("Alice", 30)
person2 = Person("Bob", 25)

# 调用每个对象的方法
person1.greet()
person2.greet()

class SharedState:
    _shared_state = {}

    def __init__(self):
        self.__dict__ = self._shared_state

class MyClass(SharedState):
    def __init__(self, value):
        super().__init__()
        self.value = value

obj1 = MyClass(10)
obj2 = MyClass(20)

print(obj1.value)  # 输出 20，因为 obj1 和 obj2 共享状态

class ObjectPool:
    def __init__(self, size):
        self.pool = [MyClass(i) for i in range(size)]
        self.index = 0

    def get_object(self):
        obj = self.pool[self.index]
        self.index = (self.index + 1) % len(self.pool)
        return obj

pool = ObjectPool(5)
obj1 = pool.get_object()
obj2 = pool.get_object()
