如何在haskell中打印列表？ [英] how do I print a list in haskell?

问题描述

如何在Haskell中将列表打印到stdout？

How do I print a list to stdout in Haskell?

假设我有一个列表 [1,2,3] 我希望将该列表转换为字符串并打印出来。我想我可以构建自己的函数，但是Haskell肯定有一个内置函数来做到这一点。

Let's say I have a list [1,2,3] and I want to convert that list into a string and print it out. I guess I could build my own function, but surely Haskell has a function built in to do that.

推荐答案

确实有一个内置功能，恰当地命名为 print 。

Indeed there is a built in function, aptly named print.

> print [1,2,3]
[1,2,3]

这是相当于 putStrLn $ show [1,2,3] 。
