如何解压缩数组？

如何在Ruby中解压缩一个数组，如Python中的这些示例：

>>> x = [1, 2, 3] >>> y = [4, 5, 6] >>> zipped = zip(x, y) >>> zipped [(1, 4), (2, 5), (3, 6)] >>> x2, y2 = zip(*zipped) >>> x == list(x2) and y == list(y2) 

Answer 1

使用transpose ：

 > zipped = x.zip(y) => [[1, 4], [2, 5], [3, 6]] > x2, y2 = zipped.transpose > x2 => [1, 2, 3] > y2 => [4, 5, 6]
