ruby - 如何以编程方式将值数组添加到键中？

Question

我是 Ruby 的新手，我想在 programmer_hash 的顶部添加一个哈希 block :

def adding_matz
    programmer_hash = 
    {
    :grace_hopper => {
      :known_for => "COBOL",
      :languages => ["COBOL", "FORTRAN"]
    },
    :alan_kay => {
      :known_for => "Object Orientation",
      :languages => ["Smalltalk", "LISP"]
    },
    :dennis_ritchie => {
      :known_for => "Unix",
      :languages => ["C"]
    }
 }
end

这是我要添加到programmer_hash 哈希顶部的内容:

:yukihiro_matsumoto => {
    :known_for => "Ruby",
     :languages => ["LISP", "C"]
}

我在方法的末尾添加了下面的代码:

programmer_hash[:yukihiro_matsumoto] = [:known_for['Ruby']]
programmer_hash[:yukihiro_matsumoto][:languages] = 'LISP'
programmer_hash[:yukihiro_matsumoto][:languages] = 'C'

它工作得很好，但我想在一行中完成所有这些，但没有任何结果是正确的。我将感谢你的帮助。

Answer 1

在主哈希中为 :yukihiro_matsumoto 键分配一个新哈希:

programmer_hash[:yukihiro_matsumoto] = { 
  known_for: 'Ruby'
  languages: ['LISP', 'C']
}
