如何展平一组阵列 - 但不是一直向下 [英] How to flatten an array of arrays - but not all the way down

问题描述

最好的转换方式是什么

[[["Club three Team one", 7800], ["Club three Team two", 7801]], [], [["Club four Team one", 7807], ["Club four Team two", 7808]], []]

进入

[["Club three Team one", 7800], ["Club three Team two", 7801], ["Club four Team one", 7807], ["Club four Team two", 7808]]

红宝石?flatten 将其一直转换为

in ruby? flatten converts this all the way down to

["Club three Team one", 7303, "Club three Team two", 7304, "Club four Team one", 7310, "Club four Team two", 7311]

推荐答案

use flatten(1) http://apidock.com/ruby/Array/flatten

your_array = [[["Club three Team one", 7800], ["Club three Team two", 7801]], [], [["Club four Team one", 7807], ["Club four Team two", 7808]], []]
your_array.flatten(1)
#=> [["Club three Team one", 7800], ["Club three Team two", 7801], ["Club four Team one", 7807], ["Club four Team two", 7808]]
