从添加新密钥的数组创建哈希(Creating hash from array adding new keys)

从添加新密钥的数组创建哈希(Creating hash from array adding new keys)

我有一个看起来像这样的数组：

data =[[01, 777], [02, 888]]

现在我想从它创建一个哈希，如下所示：

n_clip = [{"name"=>"01", "rep"=>"777"},{"name"=>"02", rep=>"888"}]

我试着这样做：

n_clip = [] data.each do |a| n_clip << Array[Hash[a.map {|| ["name", a.first]}], Hash[a.map {|| ["rep", a.last]}]] end

但它没有用，因为我得到：

n_clip = [[{"name"=>"01"},{"rep"="777"}], [{"name"=>"01"},{"rep"="777"}]]

并且最终它不是我所期望的。

I have an array looking like this:

data =[[01, 777], [02, 888]]

Now I want to create a hash from it like below:

n_clip = [{"name"=>"01", "rep"=>"777"},{"name"=>"02", rep=>"888"}]

I tried to do this in that way:

n_clip = [] data.each do |a| n_clip << Array[Hash[a.map {|| ["name", a.first]}], Hash[a.map {|| ["rep", a.last]}]] end

but it doesn't work because I get:

n_clip = [[{"name"=>"01"},{"rep"="777"}], [{"name"=>"01"},{"rep"="777"}]]

and definitively it isn't what I expected.

最满意答案

data.map { |arr| { 'name' => arr[0], 'rep' => arr[1] } }

我宁愿使用符号作为哈希键

data.map { |arr| { name: arr[0], rep: arr[1] } } data.map { |arr| { 'name' => arr[0], 'rep' => arr[1] } }

i would rather use symbols as hash keys

data.map { |arr| { name: arr[0], rep: arr[1] } }
