ruby - Ruby 中的向量化字符串连接，如 R 的粘贴函数

Question

我在 Ruby 中有两个数组，我想将它们按元素连接在一起。在 R 中，这就像使用paste函数一样简单，因为它是矢量化的：

# R
values <- c(1, 2, 3)
names <- c("one", "two", "three")
paste(values, names, sep = " as ")
[1] "1 as one"   "2 as two"   "3 as three"

在Ruby中它有点复杂，我想知道是否有更直接的方法：

# Ruby
values = [1, 2, 3]
names = ["one", "two", "three"]
values.zip(names).map { |zipped| zipped.join(" as ") }
 => ["1 as one", "2 as two", "3 as three"] 

Answer 1

另一种方法：

values = [1, 2, 3]
names = ["one", "two", "three"].to_enum 
values.map{|v|"#{v} as #{names.next}"}
# => ["1 as one", "2 as two", "3 as three"]

然而，这会在超过 2 个数组时变得更加复杂。OP 的版本更适用于多个数组。
