That doesn't solve the problem we had before though Then I'm going to append it, and keep the last change for future use.

这样没有解决我们之前的问题,所以我要给它加上一个值，让上一次的变化能够用到未来的例子中。

That isn't there. So it couldn't do it, so instead that's what append is for, is to stick things on to the end of the list.

也就是说不存在，因此没法进行指向绑定的，更改，因此这个命令并不像append那样，会在list的最后添加元素。
