Let us go away 让我们自己慢慢的走
It's going to let us bury away the specifics of something, and treat that computation like a black box. And by black box, I mean, literally behaves like a mysterious little black box.
通过抽象我们可以将一些细节,掩埋起来并将这一段计算当成黑盒,说到黑盒我的意思就是,字面上的像一个神秘的小黑盒。
So, operands. Let us take expressions, get values out, we can store them away in places, but ultimately we want to do something with them, so we need to now start talking about what are the things we can do inside of Python, or any programming language, to manipulate them.
也就是运算对象,让我们看看这些表达式,然后看看里面的这些值,我们可以把他们存在计算机的任何位置中,最终目的还是要对这些值做一些操作,因此我们现在需要开始讨论,在Python里面可以做什么,来操作它们了,或者在任何编程语言里。
