List Terraform-将列表列表转换为新列表

在Terraform中，我需要转换输入数据结构，例如：

vip_lists = [
    ["1.0.1.1", "1.0.1.2", "1.0.1.3", "1.0.1.4"]
    ["1.0.2.1", "1.0.2.2", "1.0.2.3", "1.0.2.4"]
    ["1.0.0.1", "1.0.0.2", "1.0.0.3", "1.0.0.4"]
]

要产生如下输出：

vip_sets = [
    ["1.0.1.1", "1.0.2.1", "1.0.0.1"]
    ["1.0.1.2", "1.0.2.2", "1.0.0.2"]
    ["1.0.1.3", "1.0.2.3", "1.0.0.3"]
    ["1.0.1.4", "1.0.2.4", "1.0.0.4"]
]

因此，本质上，我需要获取列表的输入列表，并创建一个输出，该输出同样是列表列表的列表，但其第0个列表是输入中每个列表的第0个元素的列表……然后第1个列表也是如此，以此类推。 我无法预先知道输入中会有多少个列表，或者它们会有多长，但是如果有帮助的话，我们可以假设这些列表都是相同的长度

我已经尝试了几乎所有我能想到的东西，并在网上搜索过，但从那以后就没有运气了。欢迎提出所有建议

这有点可怕，但它可以工作（尽管我还没有测试如果

vip\u列表

为空，它会做什么。可能会崩溃，因为我正在索引

vip\u列表[0]

，而没有检查）：

我曾经为一个模块编写过这个版本的列表，这些列表的长度不同，我们在其中使用了这样的转换，使用

count

创建了二维资源集。（当我们将它们转换为地图以与每个的ressource level

一起使用时，它们没有在atm中使用）

它可以处理动态列表大小，并以压缩或填充
null
值的方式输出：

Outputs:

compact = [
  [ "1.0.1.1", "1.0.2.1", "1.0.0.1" ],
  [ "1.0.1.4", "1.0.2.2", "1.0.0.3" ],
  [ "1.0.2.3", "1.0.0.4" ],
  [ "1.0.2.4" ],
]

matrix = [
  [ "1.0.1.1", "1.0.2.1", "1.0.0.1" ],
  [ "1.0.1.4", "1.0.2.2", "1.0.0.3" ],
  [ null,      "1.0.2.3", "1.0.0.4" ],
  [ null,      "1.0.2.4", null      ],
]

我知道答案已经被接受了，但也许有些人仍然可以使用这个动态版本。
太好了，非常感谢@carr0t，我真的很感激
