Elm：折叠多个列表的特定值

我有一个“游戏”记录列表，每个玩家都有一个分数列表。 是否可以将每场比赛中每位球员的每场得分折叠起来，以显示“总得分”

比如：

games =
    [ { id = 1
      , points =
            [ { player_id = 1, score = 20 }
            , { player_id = 2, score = 10 }
            , { player_id = 3, score = 0 }
            ]
      }
    , { id = 2
      , points =
            [ { player_id = 1, score = 20 }
            , { player_id = 2, score = 5 }
            , { player_id = 3, score = 0 }
            ]
      }
    , { id = 3
      , points =
            [ { player_id = 1, score = 20 }
            , { player_id = 2, score = 5 }
            , { player_id = 3, score = 10 }
            ]
      }
    ]

提前谢谢。

您需要一个双折，钥匙代码在那里

[ { player_id = 1, score = 60 }
, { player_id = 2, score = 20 }
, { player_id = 3, score = 10 }
]

这会得到您想要的答案，尽管格式略有不同
