So, an alternative to that that is incredibly common in just the programming world and in industry is to actually not write programs on your own personal computer but to actually write and run them on a server, someplace where the software is all standardized.
那么,在编程界和工业界普遍,使用的一个解决方案是,不在你自己的电脑上写程序,而是在服务器上编程运行,服务器上的软件都是标准化的。
I stress it in particular because I know you're all going to get into this stage; you've got a problem set due in a couple of hours, you're still writing the code, you don't want to waste time, and I'm going to use quotes on "waste time", doing those extra things to do the defensive programming, you just want to get the darn thing done.
我特别强调了这一点,因为我知道你们都会慢慢成为程序员;,你在写代码过程中造成了一系列的错误,你还在写代码,你不想浪费时间,我想把“浪费时间“用引号圈起来,浪费时间来做因为防卫性程序设计,而带来的这些额外的事情,你只想赶紧把程序写完,这不是一个好习惯,因为当你做完回头。
What we're saying is, in order to do computation, we want to describe recipes, we want to describe this sequence of steps built on some primitives, and we want to describe the flow of control that goes through those sequence of steps as we carry on So the last thing we need before we can start talking about real programming is, we need to describe those recipes.
我们在说,为了做计算,我们想描述一个方法,想描述建立在,相同基本类型上的步骤序列,而且我们想描述经过我们设计的,步骤的序列的,控制流程,因此我们开始谈论真正的编程之前,的最后一件事是,我们需要描述一下那些方法。
Those nine hours are going to be primarily working on problem sets, and all the problems sets are going to involve programming in Python, which is the language we're going to be using this term Now, one of the things you're going to see is the first problem sets are pretty easy.
这九个小时会是问题,提出的基本锻炼,所有的问题提出,都将涵盖,我们这学期,将使用的Python语言的程序,现在,你们将要看见的,第一个问题的提出非常简单。
