python中__delattr__方法

在Python中，__delattr__方法是一个特殊的魔法方法，用于在清除实例属性时被捕获执行。它的主要作用是在删除实例属性时提供自定义的逻辑。该方法的语法如下所示：__delattr__(self, 属性)。其中，self是实例方法的必须参数，属性是一个字符串，表示要删除的属性的名称。当我们重写__delattr__方法时，除了可以添加自己的逻辑外，还必须调用父类的__delattr__方法以确保相关属性被真正删除。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
