Accessing Elements in List[Int] List[Int]

Question

List(1,2,3,4,5) partition (_ % 2 == 0)

produces

res40: (List[Int], List[Int]) = (List(2, 4),List(1, 3, 5))

How do I access the lists individually. res40(0) does not seem to work.

Answer 1

You can do this to assign each partition to a different val

val (even, odd) = List(1,2,3,4,5) partition (_ % 2 == 0)

Answer 2

partition creates a pair/tuple, and you can use ._1, ._2, etc to access elements in scala tuples, see related question:

res0._1
# res2: List[Int] = List(2, 4)
