如何将数组内容作为类属性公开

class MyClass:
    def __init__(self, array):
        self.array = array

    def print_array(self):
        print(self.array)

    def add_element(self, element):
        self.array.append(element)

# 创建一个实例并传入数组
my_instance = MyClass([1, 2, 3])

# 调用方法打印数组
my_instance.print_array()  # 输出：[1, 2, 3]

# 调用方法添加元素
my_instance.add_element(4)
my_instance.print_array()  # 输出：[1, 2, 3, 4]

class MyClass:
    def __init__(self, array):
        self._array = array

    @property
    def array(self):
        return self._array

    def print_array(self):
        print(self.array)

    def add_element(self, element):
        self._array.append(element)

# 创建一个实例并传入数组
my_instance = MyClass([1, 2, 3])

# 调用方法打印数组
my_instance.print_array()  # 输出：[1, 2, 3]

# 尝试直接访问数组
print(my_instance.array)  # 输出：[1, 2, 3]

# 尝试修改数组
my_instance.array.append(4)  # 报错：AttributeError: can't set attribute
