最简单的方法是垂直合并这些数组

Question

我有这些arras

names = ["Will","Bob","John","Ben"]
ages = [45,49,32,49]
postcodes = [9320,3991,1234,2993]

什么是堆叠它们的最有效方式，因此它们显示为

people = [["Will",45,9320],["Bob",49,3991],["John",32,1234],["Ben",49,2993]]

ruby​​是否有垂直合并这些功能的功能？ （通过索引）没有所有那些讨厌的循环，简单又简单？

Answer 1

people = names.zip(ages, postcodes)

=> [["Will", 45, 9320], ["Bob", 49, 3991], ["John", 32, 1234], ["Ben", 49, 2993]]

Answer 2

您可以使用Array#zip：

people = names.zip ages, postcodes
