"In terms of diplomacy and conflict resolution, he did say that resolving the Israeli-Palestinian issue was a major input, and he immediately named Senator George Mitchell as his envoy in order to work on that particular issue,"
VOA: standard.2009.04.24
And by that, I mean, not how much memory do I need to store the size of the input, it's really how much internal memory do I use up as I go through the computation?
需要占用多少内存,我意思并不是,存储输入需要多少内存,而是当我完成这个?
bug What I typically do is I start with the input that provoked the problem, and I keep making it smaller and smaller.
我这里做的就是从引起,出现的输入开始,然后将输入,一步步的缩小规模。
> Computer our input, memory control, arithmetic, and logic and output.
>,【记录的演示】计算我们的输入,内存控制,算法,逻辑和输出。
q1 The heat input is just q1, Q and we'll define that as capital Q.
输入的热是,我们把它定义为大写的。
Even though my statement said enter a number, in particular, raw input here simply takes in a set of characters and treats it as a string.
即使我的陈述说的是应该输入一个数字,实际上,这里的原始输入会被当做一个字符,的集合来提取并被当做一个字符串来对待。
I'm going to run through a loop, and I'm going to request some input, which I'm going to read in with raw input.
我要运行一个循环,我需要一些输入,需要读入一些原始的输入。
So we can provide any form of input here and the program will just keep working.
为您提供各种形式的输入,程序也一直工作。
Which is a way of reminding you that I need to think as I write the code about what are my expectations from the input, and how might I enforce them.
通过这个我在提醒大家,在写代码的时候,要搞清楚对输入的期望,并思考下如何执行这些期望。
The only thing I've done in this part of the program, now I'm going to go and read the code, is I've gotten the user to input a bunch of data.
现在我去读读这里的代码,是我会让用户输入一些数据,然后根据用户输入的数据。
If I decide there's a better way to get input, and there is, then I can make it to change what I don't have to change the code that uses the input.
如果我觉得有更好的获取输入的方法,我可以直接改去用这种方式,而不用更改使用了,输入处的代码。
We've been using strings thus far to get input from user and store it in variables.
迄今为止,我们用字符串来接受用户的输入,然后存储在变量里。
What does it expect as input, and any other information I want to pass on.
但是如果我去做了,我将要说明这个函数是干什么的。
And its purpose in life is to maybe take input and maybe produce output.
它的唯一目的是可能是获得输入,可能是输出东西。
So one of the things I want you to notice here is that testing and debugging are not the same thing. When we test, we compare an input output pair to a specification.
这里我想大家注意的一件事,就是测试和调试是不同的两件事情,我们测试的时候,我们把输入输出,跟程序的规格说明书对比下。
Suppose instead, I want a machine that can take a recipe, the description of a sequence of steps, take that as its input, and then that machine will now act like what is described in that recipe.
假设换成这个,我想要一台可以安装描述,一系列步骤的结果的方法的机器,把那个当做输入设备,然后那台机器可以像方法中,描述的那样运行了。
The format is the same. I'm going to ask for some input, and then I am going to use that procedure to check, is this the right type of value. And I'm trying to use that to do the coercion if you like. Same thing if it works, I'm going to skip that, if it not, it's going to throw the exception.
格式是一样的,我需要一些输入,然后我要用一个过程来检查,是否是正确的值,然后你就可以做强制转换了,如果能运行,那是一样的,我打算跳过这段,如果不正确,那就会抛出一个异常。
So STR, which I just typed up there, takes in parens, some input, and it converts it into a string, so that now I can use that John where I was expecting a string. John.
因此STR,也就是,我刚刚输入的,然后把这个输入变更为一个字符串,因此现在我就能,在需要用字符串的地方使用这个对象了。
In just a couple of weeks can you start implementing things that take input from users; and if you really want to push yourselves with that particular week can you implement what we dub God mode.
几个星期之内,你就能开始执行从用户端的输入,你需要发奋苦学才能在同一个星期,实现我们的称之为God的模式。
Someone-- or someone had to implement, had to write a tool called printf that itself takes input between quotes and produces as output some characters on the screen.
需要有人去实现,这个printf函数,以双引号间的信息为输入,输出相应字母到屏幕上。
We own our own phone number, that allows you to input key strokes like you would any system and this is an example of what we call CS50 Voice.
我们都有电话号码,这就让我们可以输入任意的数字,然后这是CS50,Voice的一个例子。
I probably whip out a do while loop very rarely, but very often when programming games or any program that takes user input and has to check that user input and yell at the user if they're messing with you or aren't providing what's expected.
我可能很少用do,while,循环,但常常是,当编制程序游戏或需要用户输入的程序是,需要检查用户的输入并提醒用户,如果他们干扰了你,或没有提供所期望的输入。
Go ahead and implement with the person next to you a program that takes as input from the user an integer called F and prints out the answer of the Celsius equivalent.
继续和你旁边的人执行程序,取来自用户的整数F作为输入,然后打印出与之等价的摄氏温度的答案。
It ran through that sequence of instructions, in particular it bound x to the value three, x and then it took x times x, got the value of x multipied by x, which of course is nine, bound that to the value of x, and then it printed out the value, and now it's sitting here waiting for an input.
程序按照指令的顺序去执行的,首先是把x和3这个值进行了绑定,然后把x乘以,得到了x乘以x的值,当然也就是9了,然后把x和这个值进行了绑定,然后显示出这个值,然后就等待输入。
human text, ASCII text as input and output zeroes and ones that represent that program in a manner that the CPU, interesting, dammit, not installed on this computer.
编译器以人输入的文本,ASCII码为输入,它输出一些cpu实际上可以理解的,在这台计算机上没有安装。
So we'll talk a bit more about this idea of functions today, but, get int, again, can think of it as a black box, whose purpose in life is to prompt the human for input and pester the human if he or she doesn't actually give it int, but then once it has that, has entered it from the user, it's quote unquote, returns it to you.
所以我们进今天将多讨论点这个函数的概念,但是,GetInt,我们可以把它当做一个黑盒子,它的唯一目的是提示人们来输入,并且如果他或她没有,给它int数,则会纠缠用户,但是一旦它得到了,用户输入的int数,对输入进行引用,返回给你。
Why is this much nice? Well, that's a handy piece of code. Because imagine I've got that now, and I can now store that away in some file name, input dot p y, and import into every one of my procedure functions, pardon me, my files of procedures, because it's a standard way of now giving me the input.
为什么这样很好呢?,这是一段很好用的代码,因为想象下如果我有了这段代码,我能把它用某个文件名保存起来,后缀是。py,导入到所有的处理函数中,抱歉,我的处理文件,因为这是一个标准的输入方法。
