ruby - 以随机顺序将数组拆分为多个数组 - Ruby

Question

我试图在每次运行时以随机顺序将一个名称数组拆分为多个数组。我知道如何拆分它们:

 name_array = ["bob","john","rob","nate","nelly","michael"]
 array = name_array.each_slice(2).to_a
 => [["bob", "john"], ["rob", "nate"], ["nelly", "michael"]]

但是，如果我希望它每次都以随机顺序吐出它们怎么办？

Answer 1

在做同样的事情之前，打乱数组。 ( Array#shuffle )

name_array.shuffle.each_slice(2).to_a
# => [["nelly", "nate"], ["rob", "bob"], ["michael", "john"]]

或者，之后根据您的需要随机播放:

name_array.each_slice(2).to_a.shuffle
# => [["nelly", "michael"], ["rob", "nate"], ["bob", "john"]]
