创建字符串映射到列表 [英] Create a map of string to List

问题描述

我想创建一个字符串映射到container/list.List实例.这是正确的解决方法吗?

I'd like to create a map of string to container/list.List instances. Is this the correct way to go about it?

package main

import (
    "fmt"
    "container/list"
)

func main() {
    x := make(map[string]*list.List)

    x["key"] = list.New()
    x["key"].PushBack("value")

    fmt.Println(x["key"].Front().Value)
}

推荐答案

每当我想使用List时，我都发现切片是正确的选择，例如

Whenever I've wanted to use a List I've found that a slice was the right choice, eg

package main

import "fmt"

func main() {
    x := make(map[string][]string)

    x["key"] = append(x["key"], "value")
    x["key"] = append(x["key"], "value1")

    fmt.Println(x["key"][0])
    fmt.Println(x["key"][1])
}
