Scala：元組的並行賦值

Question

是否可以在Scala中並行分配元組成員。如果不是有另一種技術來完成類似的東西？

val players = List(
    new Player("Django Reinhardt", 42), 
    new Player("Sol Hoopii", 57), 
    new Player("Marc Ribot", 64) 
) 

val winners, losers = players.partition(p => p.score > 50) 

// winners = List(Player name:Sol Hoopii score: 57, Player name:Marc Ribot score: 64) 
// losers = List(Player name:Django Reinhardt score: 42) 

Answer 1

val winners, losers = players.partition(p => p.score > 50) 

Assignes的（列表，列表）元組的兩個變量。如果你想解開元組，你必須使用

val (winners, losers) = players.partition(p => p.score > 50) 

這正是你想要的。 :-)
