Map.merge() – One method to rule them all

But your python code is still really ugly. In Scala:

import scala.collection.mutable.Map

> val map = Map.empty[String, Int]

> List("hi", "there", "hi").map { x =>

> map(x) = i

> }

Not the same but immutable approach is more idiomatic Scala.

    List("hi", "there", "hi")
      .zipWithIndex
      .map { case (x, i) =>
        x -> i
      }.toMap

That example doesn’t really illustrate the point of updating maps with repeated values.
