如何在红宝石中打印多维数组? [英] How do I print a multi-dimensional array in ruby?

问题描述

在ruby中打印多维数组的首选方法是什么?

What's the preferred method of printing a multi-dimensional array in ruby?

例如，假设我有这个2D数组:

For example, suppose I have this 2D array:

x = [ [1, 2, 3], [4, 5, 6]]

我尝试打印它:

>> print x
123456

还有什么是行不通的:

>> puts x
1
2
3
4
5
6

推荐答案

如果您只是在寻找易于阅读的调试输出，则"p"很有用(它在数组上调用inspect())

If you're just looking for debugging output that is easy to read, "p" is useful (it calls inspect() on the array)

p x
[[1, 2, 3], [4, 5, 6]]
