命令式编程(Imperative Programming)和声明式编程(Declarative Programming)都是计算机编程的范式,它们有着不同的特点和适用场景。 首先,我们讨论命令式编程。在命令式编程中,程序员需要明确地告诉计算机需要执行哪些步骤来达到预期的结果。我们可以把这种范式比作烹饪食谱:食谱会明确地告诉你需要什么成分,然后应该按照什么顺序进行哪些步骤
最近在向刘编辑@鲔鱼da(我也不知道他为什么结尾有个da,可能是卖萌吧)学习Pytorch,其中提到了Pytorch的两个特点Imperative programming和Dynamic Computation Graphs. 今天就给大家讲讲Imperative programming以及和其并列Declarative programming具体指的是什么。 简单的定义 命令式编程(Imperative):详细的命令机器怎么(How)去...

命令式编程(Imperative Programming)和声明式编程(Declarative Programming)是计算机编程的两种范式,各自有独特特点及适用场景。命令式编程侧重于详细说明计算机执行步骤以达到结果。类比烹饪,编程者需明确告知需要哪些材料及操作顺序。例如,计算数组元素总和,Python命令式编程代码如下:我们直接告知计算机执行...

In contrast to the imperative one,declarative programmingis about describing what you're trying to achieve, without instructing how to do it. Let's convert the imperative example above into a declarative one (using promise-like constructs): ...

A common use case of declarative programming is setting the parameters of some well-defined workflow. For example, when you order in a coffee shop, you may just tell the waiter "bring me a cup of coffee with sugar and milk." You don't need to give step-by-step instructions on how ...
