List 在clojure中为向量列表中的元素编号

我有一个要编号的向量列表。例如，我有以下几点 向量列表

(["blah1" "blah2" "blah3"]
 ["clah1" "clah2" "clah3"]
 ["flah1" "flah2" "flah3"])

我想要这样的东西：

(["line 1" "blah1" "blah2" "blah3"]
 ["line 2" "clah1" "clah2" "clah3"]
 ["line 3" "flah1" "flah2" "flah3"])

map将多个序列作为最后一个参数：

user=> (map vector (iterate inc 1) '(a b c d))
([1 a] [2 b] [3 c] [4 d])

地图索引

可以做到这一点

(map-indexed (fn [i v]
               (into [(str "line " (inc i))] v))
             [["blah1" "blah2" "blah3"]
              ["clah1" "clah2" "clah3"]
              ["flah1" "flah2" "flah3"]])
;; => (["line 1" "blah1" "blah2" "blah3"] ["line 2" "clah1" "clah2" "clah3"] ["line 3" "flah1" "flah2" "flah3"])

              ["clah1" "clah2" "clah3"]

;; => (["line 1" "blah1" "blah2" "blah3"] ["line 2" "clah1" "clah2" "clah3"] ["line 3" "flah1" "flah2" "flah3"])

您还可以执行

（映射向量（rest（range））'（abcd））

您还可以执行

（映射向量（rest（range））'（abcd））
