Scala: List of pairs to pair of lists

Question

I have a list of pairs:

val pairs = List("a" -> 1, "b" -> 2, "c" -> 3)

I'd like to convert it to a pair of lists:

List("a", "b", "c") -> List(1, 2, 3)

Basically, I want the opposite of zip()

Any elegant way of doing so?

Answer 1

The opposite of zip? What might that be? unzip maybe?

scala> List("a" -> 1, "b" -> 2, "c" -> 3).unzip
res0: (List[java.lang.String], List[Int]) = (List(a, b, c),List(1, 2, 3))
