如何从派生类中只获取基类属性？

class BaseClass:
    def __init__(self, base_property):
        self.base_property = base_property

class DerivedClass(BaseClass):
    def __init__(self, base_property, derived_property):
        super().__init__(base_property)
        self.derived_property = derived_property

# 创建派生类的对象
derived_obj = DerivedClass("Base Property", "Derived Property")

# 使用基类的引用来引用该对象
base_ref = derived_obj

# 通过基类的引用访问基类的属性
print(base_ref.base_property)  # 输出：Base Property
