arrays - Ruby 重启数组循环

Question

一旦遍历整个数组，我将尝试在 ruby​​ 中重新启动数组循环。

我发现 retry 方法对此不起作用。代码如下:

letters = ["A","B","C"]

letters.each do |letter|
  puts letter
  if letter == letters.last
    puts "that was the last letter"
    #restart the array from A again (I'd like it to continue looping infinitely)
  end
  sleep 1
end

任何想法将不胜感激。谢谢!

Answer 1

使用循环。

letters.cycle do |letter|
  ...
end
