So that's the key thing to-- to realize; that what the assignment did was have two separate paths to the same object.
认识到赋值会造成两个独立的绑定到;,同一对象上这件事情很关键,因此我可以通过这一条或者。
-
And so you could construct all subsets, check that the weight is less than the weight of the knapsack, and then choose the subset with the maximum value.
因此你可以构建所有子问题，判断它的重量,是否小于背包的重量，然后选择值最大的子问题。
-
And in contrast, in the lower left hand part of the periodic table, these 2 quantities are low, so also what we're going to see is low electronegativity.
相反地，在周期表的左下部分，这两个量的值都很小，因此我们会看到这里的电负性也很低。
-
The reason for inexact doesn't mean it's a crummy measurement, t means that it's path dependent, and so the value of this integral depends on how you get from one to two.
这是因为它是,与积分路径有关的，因此这里的积分值，取决于从一端到二端的,具体路径。
-
So,the combination of survivorship bias and backfill bias for that one year made 4.3 percentage points difference.
因此在生存偏差和回填偏差的共同作用下,造成了两个收益率之间4.3%的差值
-
The peak occurs a little bit later and then there's a less rapid decline here, and then blood sugar actually ends up a little above this initial level, and therefore you're less likely to eat because you're less hungry.
峰值出现得比较晚,下降也较为缓慢,最后血糖结束在比起始值稍高的位置,因此人就没有那么想进食 因为不感觉饿
-
So I can solve out for X.
因此我能解出X的值
-
So, when we think about a bond length, this is going to be the length of our bond here, that makes sense because it's going to want to be at that distance that minimizes the energy.
因此，当我们考虑一个键的长度的时候，这就应该是我们的键长，这是合理的,因为体系会在核间距达到这一距离时,能量到达最小值。
-
And I want to stress this, we're going to come back to it later on in the term, so the way I'd like you to think about it for now, is that somewhere in the machine, there's a big space that contains all possible values.
我想要强调一点，我们在晚些时候,还会回头来讲这一点，因此现在,我需要你们形成这么一个观点，就是在计算机的某处，有一个包含了所有可能值的,很大的空间，好。
-
Need to get the base in. Second thing I want to do, I need to get the height, so I'm going to input a value for the height, also as a float, a floating point.
也就是输入底的值，第二件我想要做的，事情就是得到三角形的高,因此我会输入一个值作为三角形的高，同样也是一个浮点数。
-
And so, in fact, if I wanted the other version of it, in fact, if I do this right, 23 it's going to give me 23 because it does the multiplication first, if I wanted the other version of it, Python I need to tell it that, by using, excuse me, parentheses.
因此，实际上，如果我想换种做法，实际上，如果我去执行这个表达式，返回值是3,因为乘法会被优先执行，如果我需要换种做法，我需要告诉，用括号来告诉它。
-
As you know, income inequality is getting worse, low-income wages are not going up, so that component of housing has been declining in real terms.
众所周之,收入的不平等愈演愈烈,低收入者的工资不会上涨,因此以实际值计算的这部分成本是下降的
-
As a consequence, I can now refer to that just by its name.
因此，我现在可以通过这个名字，来访问这个值。
-
So, any place it's legal to use the value.
因此，在任何可以合法使用值的地方,都可以使用变量。
-
All right. So these are extremely valuable.
好，因此这些东西都是可以当做值的。
-
So, a pair or collection of those two values.
因此一对或者一系列的两组值。
-
I'm taking advantage of the fact that start is going to be a point, and I'm just directly saying, John give me your x-value.
我利用了开始是一个点这个事实,然后我就直接说，返回给我你的x值，因此我不知道。
-
And built up the list corresponding to the three items that the user entered.
建立起对应的数组来，因此这里,我能得到的唯一中间值就是res了。
-
So if this is true do something else, true otherwise test and see if this is true, do something else, as many as I like followed by the end.
因此如果结果为true那么做一些操作，否则的话再看看这个表达式的值是不是，如果是的话做另外一些操作，我想要多少后面就可以跟多少。
-
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。
-
Doesn't need to be, so, what should I do about the upper bound here?
不必改下边界值，因此,我该对上边界值做个怎么样的改动呢？
-
Numbers are hard. That's why we teach whole semesters worth of courses in number theory.
因此我们整个学期关于数学理论,的学习也是物有所值。
-
All right. Second question: or maybe a better way of saying this, and the general format you're likely to see here is, a test involving a variable name, which must be initialized outside of the loop, and which interior to the loop gets changed, so that the test is going to change.
好，第二个问题：,换种更好的方式来说吧，你们通常喜欢的,方式是，这个测试涉及到一个变量名字，变量在循环外已经被初始化，然后循环内部会改变这个变量的值，因此测试结果会改变。
-
PROFESSOR2: So it's not really a Boolean-valued function.
教授2：因此这并不是一个,真正的布尔值的函数。
-
Well, what I always do in anything like this is, the first thing I do is, I run it on something where I can actually compute the answer in my head. So I get a sense of whether or not I'm doing the right thing.
好的，我常常在,这种问题中会做的是，我会做的第一件事是我,会先带入我可以心算的值来运行,因此我能够知道我是否做对了。
-
And remind you that inside of here, I'd better be changing the variable. All right, if that variable that's counting is not changing I'm going to be stuck in an infinite loop, so I ought to that, right, expect somewhere in there, a change of that variable. All right?
我最好改变了计数器的变量值，好，如果计数的变量没有变化的话，我就会被卡在一个无限循环里面,因此我应该【不可闻的声音】,对，在这里的某个地方，改变下计数器的变量，对不对？我要做的最后一件事情就是？
-
So, these are two different definitions of how to think about atomic radius, but really what you find when these are measured is they come up with almost the identical values, so there are tables, you can look up of atomic radii and see these values, and you can trust them that, they work for both this definition and for this definition here, in most cases.
这就是,关于原子半径的两种不同的定义，但实际上你会发现按照这两种方法,测量出的值是相等的，因此有很多关于原子半径的表格，你可以通过查阅它找到这些值，你可以相信这些值，它们对于这两种定义都是适用的，在大多数情况下。
-
For an angular node, we're just talking about what the l value is, so whatever l is equal to is equal to the number of angular nodes you have.
对于角向节点，我们其实就是在讨论l，的值是多少，因此不管，l，的值等于几,它就等于你所有的角向节点的数目。
-
In either case, I take that value and multiply back by two, if it was even I get back the original number, if it was odd, I'm not going to get back the original number, so I can just check to see if they're the same.
在两种情况中，我都把结果值,再乘以2，如果x是偶数我就,得到了原来的值，如果x是奇数那么就不会得到,原来的值，因此我看看得到的值,和原来的值相等不相等就可以了。
-
Did the same thing with c p 2, 2 2 0 Again, remind you, c p 2 is a different instance of this data type.
建立了一个x变量，我也把它赋值为，因此cp1内置有了x和y值,然后对cp2做同样的操作。
