golang地图打印混乱

Question

为什么地图打印混乱，我该如何使其秩序井然？

package main

import (

    "fmt"

)

type monthsType struct {

    no   int

    text string

}

var months = map[int]string{

    1:"January", 2:"Fabruary", 3:"March", 4:"April", 5:"May", 6:"June",

    7:"July", 8:"August", 9:"September", 10:"October", 11:"Novenber", 12:"December",

}

func main(){

    for no, month := range months {

        fmt.Print(no)

        fmt.Println("-" + month)

    }

}

打印输出：

10-October

7-July

1-January

9-September

4-April

5-May

2-Fabruary

12-December

11-Novenber

6-June

8-August

3-March

Answer 1

地图未排序，因此您可以使用切片对地图进行排序。马克·萨默菲尔德（Mark Summerfield）的书“ Go中的编程”在第204页上对此进行了解释，强烈建议使用。
