字符串到字符列表

Question

我想知道我是否可以将字符串转换为字符列表？

"jt5x=!" -> ["j","t","5","x","=","!"]

基本上,它会是？

example :: String -> [Char]

Answer 1

(将评论收集到答案中)

因为在haskell中,a String 是一个字符列表,即[Char]只返回给定的输入.

example = id

做你想要的.注意,id定义为

id x = x

您的示例"jt5x=!" -> ["j","t","5","x","=","!"]与描述不匹配:双引号""括起来String不是单个引号Char.对于字符使用单引号'.你可以输入

"jt5x=!" == ['j','t','5','x','=','!']

进入GHCi并看到它回归True.键入map (:[]) "jt5x=!"实际看到["j","t","5","x","=","!"].
