But you'll see that once you get to final projects frankly, you're not gonna want to implement everything from scratch.
但是一旦你得出了最终方案,你就不会愿意利用框架去,实现任何功能了。
but unfortunately the days when I could go were never available. It didn't work out.
但可惜的是,我没时间去。没能实现这个心愿。
Well, if you're going to do that, you've got to be able to find what you're looking for in a page in two steps.
如果让你去实现的话,你肯定是通过两个步骤,去找你想要的网页中的内容的。
So the king told his assistant to go and get the man, give the man his wish.
国王指示助手,去实现他的愿望。
They've managed to procure no more than a burial plot in the Promised Land Even God has left his land, descending with the Israelites into Egypt, so the promises and their fulfillment seem quite remote.
他们只试图在应许之地获得一块葬身之地,甚至上帝也离开了他的土地,与以色列人一起下埃及去,因此许诺和它们的实现似乎相去甚远。
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。
you have to realize it's only maybe 5% of the success.
你就要去实现它,也许它只是成功的5%。
They build them, they do what if games, they play with them, and then they try and adjust them to get them right The nice thing here is, you can decide whether you believe momentum and see what it would mean, or not mean, etc.
他们实现建立程序,他们去做“要是“游戏,他们不断尝试,然后他们不断调整最终得到正确结果,最好的一件事就是,你可以决定你是否相信这个股票势头,看看它到底意味着什么或根本没有意义。
It says, well I'm going to print out first and last just so you can see it, and then I say, gee 2 if last minus first is less than 2, that is, if there's no more than two elements left in the list, then I can just check those two elements and return the answer.
然后它计算了尾点和开始点的差,如果小于2的话,也就是说数组中的元素小于等于,我对这两个元素进行比较,然后返回结果就可以了,否则的话,我们就去寻找中值点,注意它是怎么实现的,首先这个指向一个列表的开头。
It means anybody using that little function get float doesn't have to worry about what's inside of it. So for example, I decide I want to change the message I print out, I don't have to change the function, I just pass in a different parameter.
这代表着用这个方法去获得浮点数,的任何人都不用担心具体的实现了,例如,如果我想改变下,显示的信息的话,我不必去改变方法,我传个不同的参数就可以了。
I'm using it as an abstraction, saying I'm going to have square root from somewhere, maybe I'll build it myself, maybe somebody gives it to me a s part of a library, so I'm burying the details inside of it.
我把这个方法作为一个抽象来引用,意味着我将会从另外一个,地方去求一个数的平方根,可能我会自己写这个方法,也可能我会从别人写的lib中去引用,因此我将实现的细节放到了其他地方。
But what looks like this orange block as of now in Scratch, add orange to your so called inventory, well, it's gonna take at least two lines of code in C to actually create the inventory array with this first line and then put something like the word orange inside of it.
就好比Scratch里面橘色的这一块,把“桔子“加到所谓的“清单“里面去,在C语言中至少需要两行代码来实现,第一行代码创建一个货单数组,第二行就需要把“桔子“放进去。
So we want to write programs to do that.
为了实现这一目标我们要去写一个执行程序。
Another way of saying it is, anything that uses get float doesn't care what the details are inside or shouldn't, and if I change that definition, I don't have to change anything elsewhere in my code, whereas if I just have the raw code in there, I have to go off and do it.
换种说法就是,任何用到获取,输入这个功能的人不用担心具体的实现细节,如果我改变了这里的实现,我并不需要去改变我的代码,因为我的最底处的源码就在这里,我去改这里就可以了。
And the challenge is to combine "the permission to be human" to experience the emotion to go through the motion and yet not to enter the downward spiral where six months later, after small incident, I'm still in that rot.
困难在于将之与准许为人相结合“,去体会情绪,实现转移,但不会进入下行螺旋,在发生小小意外六个月后,仍心情低落。
So in other words, if thankful is still false at this point, it means this condition did not work out very well, and so I'm going to do this block of code again.
换句话说,如果thankful在这时候还是false值,这表示这个条件没有实现地很好,所以我将再次去处理这段代码。
All right. What does this have to do with my divisor example? This says I can make tuples, but imagine now going back to my divisor example and I want to gather up the elements as I go along. I ought to be able to do that by in fact just adding the pieces in.
这意味着我可以创建元组了,但是想像下回到我们的除数的例子,在处理过程中我们想把目标数的除数,收集起来,我应该能够通过把这些数,一个一个加进来来实现这个目的,我正是要去这么做,也就是。
