But a point I'm trying to make is, it sounds like anymore computers have gotten so blazingly fast, why should you worry about it?

但是这里我要讲的一点是，在任何一台计算机,都能这么快的运算的情况下，我们还管效率这个问题干嘛呢？

The mind reflects the workings of the brain just like computation reflects the working of a computer.

心理反映了大脑的活动,就像运算结果反映了计算机的运行一样

You could use a calculator or any number of other tools but we'll get there.

我们可以用一个计算器或,其他的运算工具来计算那个结果。

Because in doing that, Python would then have a value that it could pass on into some other part of a computation, and if it wasn't what I wanted, I might be a long ways downstream in the computation before I actually hit some result that makes no sense.

因为如果这样做的话，Python会将,输入的值传递到下面的,一些运算中去，如果这个值的类型不是我想要的，我可能会在得到,一个毫无意义的结果之前,经历一个很长时间的,计算过程。

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。
