动态语言 [英] Dynamic languages
问题描述
我一直在阅读E-Week上发表的题为Microsoft
Lures开源程序员的文章，其中包含动态
语言的定义如下：
动态编程语言使程序在运行时可以更改其结构。
我想知道这个定义是否正确。
我们可以用这种方式定义动态语言吗？

我怀疑这是他们的意思意思是，动态语言是一种语言
仍然在发展（Python）而不是死语言（COBOL）。
它们可能指的是可以在运行时添加和删除组件的程序
。

动态是指变量的输入。在Python中，变量在赋值时动态获得

这些语言被称为动态类型语言，这意味着
有一种静态类型语言，那里有是。
所有语言都是动态的，这种俚语是糟糕的计算机科学。没有
就像静态计算机语言一样。

I''ve been reading an article published in E-Week entitled "Microsoft
Lures Open-Source Programmer", which contains a definition for dynamic
languages as follows:
"Dynamic programming languages enable programs to change their
structure as they run."
I wonder if this definition is correct.
Can we define dynamic languages this way?

I doubt that this is what they mean but a dynamic language is a language
that is still evolving (Python) as opposed to a dead language (COBOL).
They probably are referring to programs that can add and remove components
during runtime.

Dynamic refers to the typing of variables. In Python variables get a
type dynamically when assigned a value.

Those languages are called dynamically typed languages, this implies that
there is a statically typed language, which there is.
All languages are dynamic, this slang is bad computer science. There is no
such thing as a static computer language.
