Ruby：将两个散列合并为一个并与值相连 [英] Ruby: merge two hash as one and with value connected

问题描述

$ 2
$ b

  h1 = {s1=> 2009-7-27，s2=> 2010-3-6，s3=> 2009-7-27} 
 
 h2 = {s1=> 12:29:15，s2=> 10:00:17，s3=> 12:25:52} 
  

我想将这两个散列合并为一个像这样的：

  h = {s1=> 2009-7-27 12:29:15，
s2=> 2010-3-6 10:00:17，
s3=> 2009-7-27 2:25:52} 
  

要做到这一点的最佳方法是什么？谢谢！

解决方案

  h = h1.merge（h2）{|第二|第一个++第二个）
  

如果您的密钥相同，在你的代码中，它们不是（s1vss1 =）。他们应该是相同的钥匙？

2 hash:

h1 = { "s1" => "2009-7-27", "s2" => "2010-3-6", "s3" => "2009-7-27" }

h2 = { "s1" => "12:29:15", "s2" => "10:00:17", "s3" => "12:25:52" }    

I want to merge the two hash as one like this:

h = { "s1" => "2009-7-27 12:29:15",
      "s2" => "2010-3-6 10:00:17", 
      "s3" => "2009-7-27 2:25:52" }

what is the best way to do this? thanks!

解决方案

h = h1.merge(h2){|key, first, second| first + " " + second }

It will work if your keys are the same. In your code, they aren't ("s1" vs "s1="). Are they supposed to be the same keys?
