I have a list of N lists, each sub-list containing M elements.

How do I create a list of M lists with N elements each, containing the n-th elements from the initial lists?

Let's say I have this

```
myList = [[1, 2, 3],[4, 5, 6]]

```

I want to have

```
[[1, 4],[2, 5],[3, 6]]

```

Performance is also important. I have sublists of millions of elements (though, one dimension will always be small: like 1.000.000 x 8 )
