go初学爬虫问题，关于切片的用法

[s466579141s]

                var info map[string]interface{}
                var HouseType []map[string]interface{}

		var housedetail map[string]interface{}

		housedetail["Housetype"] = housetype
		housedetail["Housearea"] = housearea
		housedetail["HousepriceMax"] = housepriceMax
		housedetail["HousepriceMin"] = housepriceMin
		housedetail["Housedirection"] = housedirection
		housedetail["Housedusage"] = housedusage
		housedetail["Housesell"] = housesell
		housedetail["Housesdeal"] = housesdeal

		HouseType = append(HouseType,housedetail)
		
                info["HouseType"] = HouseType

info是存所有房屋信息的，其中一个数组字段是房型HouseType，里面有很多个map，存了各种房型的信息。
应该就是这一段出了问题跑不了

已经解决

package main

import (
	"fmt"
	//"gospider/libs"
)

func main() {

	info := make(map[string]interface{})

	HouseType:= []map[string]interface {}{}

	housedetail := make(map[string]interface{})

	housedetail["Housetype"] = "3房2厅1卫"
	housedetail["Housearea"] = 900

	HouseType = append(HouseType, housedetail)

	info["HouseType"] = HouseType
	info["Price"] = 900
	info["Comp"] = "恒大"

	fmt.Println(info)
}

然而不知道为什么这么写

map需要make(或者说new)吧 切片可make 也可以不用make
