通过{ get；}将值传递到私有类

class PrivateClass:
    def __init__(self):
        self.__private_property = None

    def get_private_property(self):
        return self.__private_property

    def set_private_property(self, value):
        self.__private_property = value


# 创建私有类对象
private_obj = PrivateClass()

# 通过setter方法设置私有属性的值
private_obj.set_private_property("Hello World")

# 通过getter方法获取私有属性的值
value = private_obj.get_private_property()
print(value)  # 输出：Hello World
