clojure 将惰性序列转换为哈希映射 [英] clojure convert lazy-seq to hash map

问题描述

我是 clojure 初学者.如何从 lazySeq 创建地图?

I'm a clojure beginner. How do I create a map from a lazySeq?

(def fields [:name :age :color])
(def values ["joe" 32 "red"])
(def record (interleave fields values))

(def mymap (into {} record))  ;; ????

;; (get mymap :age)
;; 32

推荐答案

回答您的实际问题:

(apply hash-map record)

但由于您实际上已经有单独的键和值，我建议跳过交错步骤而改为编写

But since you actually already have separate keys and values, I would suggest skipping the interleave step and instead writing

(zipmap fields values)

或者，如果您对 into 一心一意，您可以

Or if you have your heart set on into, you could

(into {} (map vector fields values))
