In there, I want to make this distinction, this nuance: the evaluator is still going to be taking those expressions and using its rules to get a value, but it's not going to print them back out.

在这里，我想要做这么一个，细微差别：运算器依然会,对表达式,进行求值，但是不会,显示结果值。

It's using its set of rules to deduce the value and print them back out.

计算器用自己的规则,去计算出结果来并返回。

But that little short hand there is doing exactly the same thing. It is adding that value into some digits and putting it back or signing it back into some digits. And I'll walk through that loop and when I'm done I can print out the total thing does. And if I do that, I get out what I would expect.

加上得到的这个数的,但是这个缩写声明其实是进行了同样的操作,它把我们得到的这个数加到一个数上面去,然后用和对这个数进行了重新赋值,在循环中会去遍历字符串，当完成循环后,程序会显示数字的总和，如果我运行，这个程序的话，我会得到我期待的结果。

I have a sequence of commands; I've got an assignment statement, I've got another assignment statement, I've got a print statement, I've got an input statement, which we'll come back to in a second.

这是一系列的命令;,我有了一个赋值声明，然后是另外一个赋值声明，还有一个print声明，然后是一个input声明，我们稍后会讲讲这个生命。

That's the Python saying, that is a command, that is a specific command to get the value of the expression and print it back out.

这代表着Python告诉我们这是一个命令，这是一个,得到表达式的值,并显示的特殊命令。
