最簡單的方式垂直

Question

我有這些掛毯

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

請告訴我，使他們出現

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

是否紅寶石有一個功能，垂直合併這些最有效的方式堆疊起來？ （按索引）很好又簡單，沒有所有那些討厭的循環？

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
