Ruby:在初始化哈希时减少重复

Question

array = [0, 0.3, 0.4, 0.2, 0.6]

hash = {
   "key1" => array[0..2],
   "key2" => array[0..3],
   "key3" => array,
   "key4" => array,
   "key5" => array,
   "key6" => array,   
   "key7" => array
}

有没有办法通过做类似的事情来删除重复

hash = {
   "key1" => array[0..2],
   "key2" => array[0..3],
    %(key3, key4, key5, key6, key7).each {|ele| ele => array}
}

Answer 1

尝试

array = [0, 0.3, 0.4, 0.2, 0.6]
hash = {
   "key1" => array[0..2],
   "key2" => array[0..3]
}
%w(key3 key4 key5 key6 key7).each {|ele| hash[ele] = array}
