How do I print a list to stdout in Haskell?
如何在 Haskell 中将列表打印到标准输出？
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.
假设我有一个列表[1,2,3]，我想将该列表转换为字符串并打印出来。我想我可以构建我自己的函数，但肯定 Haskell 内置了一个函数来做到这一点。

Indeed there is a built in function, aptly named print.
确实有一个内置函数，恰如其分地命名为print.
> print [1,2,3]
[1,2,3]
This is equivalent to putStrLn $ show [1,2,3].
这相当于putStrLn $ show [1,2,3].
