在clojure中生成从'a'到'z'的字符序列 [英] Generate character sequence from 'a' to 'z' in clojure

问题描述

我想生成从a"到z"的字符序列.在scala中，我可以非常简单地生成字符序列:

I want to generate character sequence from 'a' to 'z'. In scala, I can generate character sequence very simply:

('a' to 'z')

但是在 clojure 中，我最终得到了以下代码:

But in clojure, I end up with the following code:

(->> (range (int a) (inc (int z))) (map char))

或

(map char (range (int a) (inc (int z))))

在我看来，这很冗长.有什么更好的方法吗?

It seems to me verbose. Are there any better ways to do it?

推荐答案

如果代码看起来冗长"，通常只是表明您应该将其分解为一个单独的函数.作为奖励，您有机会为函数指定一个有意义的名称.

If code looks "verbose" it's often just a sign that you should factor it out into a separate function. As a bonus you get the chance to give the function a meaningful name.

只要做这样的事情，你的代码就会更具可读性:

Just do something like this and your code will be much more readable:

(defn char-range [start end]
  (map char (range (int start) (inc (int end)))))

(char-range a f)
=> (a  c d e f)
