Python to Scala Collections
Type Mappings
| Python | Scala |
|---|---|
list[T] | List[T] or mutable.ListBuffer[T] |
dict[K, V] | Map[K, V] or mutable.Map[K, V] |
tuple[T, ...] | (T, ...) or Vector[T] |
set[T] | Set[T] |
Sequence[T] | Seq[T] |
Iterable[T] | Iterable[T] |
Iterator[T] | Iterator[T] |
Mutable Collections
import scala.collection.mutable
// Python: list with append -> mutable.ListBuffer
val buf = mutable.ListBuffer.empty[Token]
buf += token
// Python: dict -> mutable.Map
val reg = mutable.Map.empty[String, TokenContainer[T]]
reg(key) = container
Collection Operations
// Python: [f(x) for x in xs] -> xs.map(f)
// Python: [x for x in xs if p(x)] -> xs.filter(p)
// Python: enumerate(xs) -> xs.zipWithIndex
