如何访问对象的继承的受保护字段

class Parent:
    def __init__(self):
        self._protected_field = "Protected"

    def get_protected_field(self):
        return self._protected_field

    def set_protected_field(self, value):
        self._protected_field = value


class Child(Parent):
    def __init__(self):
        super().__init__()

    def get_protected_field(self):
        return super().get_protected_field()

    def set_protected_field(self, value):
        super().set_protected_field(value)


child = Child()

# 访问受保护字段的值
print(child.get_protected_field())  # 输出：Protected

# 修改受保护字段的值
child.set_protected_field("New Value")
print(child.get_protected_field())  # 输出：New Value
