0x00002022-11-26 来自广东执行del删除tuple，是不是为了回收内存？ 另，tuple的发音应该是“塌破”[tʌpl]吧？作者回复: 塌破 ，我再练习几遍 del 准确来说是删除 变量名和 tuple对象之间的联系， 一旦tuple对象没有变量继续引用它了，tuple对象会等待Python解释器释放，释放以后才能进入到内存回收

水里捞鱼2023-02-07 来自北京1. .insert()、.append() 方法均不存在：tuple本身不支持增加元素，报错信息为 AttributeError: 'tuple' object has no attribute 'remove' 2. .remove() 同理；del 删除元素 报不支持该命令：TypeError: 'tuple' object doesn't support item deletion 3. 不存在第四个元素，因此报索引错误：IndexError: tuple index out of range1
