在Ruby中执行类似"Sentences.each.each"的最干净的方法

Question

假设我有一系列句子:

a = ["I love pie", "I love you more and more each day", "every day is a good day"]

我想测试句子中的每个单词.因为红宝石太棒了我以为a.each.each可能有用,但事实并非如此.有没有一个干净的方式,而不必在每个内部嵌套？

Answer 1

a.each { |sentence| sentence.split.each { |word| # do something with the word } }

或者稍长的格式,如果:

a.each do |sentence|
  sentence.split.each do |word|
    # do something
    # do something
    # do something
  end
end
