问题描述
我有这个:
hash = { "a"=>["a", "b", "c"], "b"=>["b", "c"] }
我想得到这个:[["a","b","c"],["b","c"]]
这看起来应该有效，但它没有:
This seems like it should work but it doesn't:
hash.each{|key,value| value}
=> {"a"=>["a", "b", "c"], "b"=>["b", "c"]}
有什么建议吗?
推荐答案
还有，稍微简单一点....
Also, a bit simpler....
>> hash = { "a"=>["a", "b", "c"], "b"=>["b", "c"] }
=> {"a"=>["a", "b", "c"], "b"=>["b", "c"]}
>> hash.values
=> [["a", "b", "c"], ["b", "c"]]
