Go map of traversing range

// MapFunc03 ... Map of the traverse range 
FUNC MapFunc03 () { 
    m: = the make (Map [ String ] String ) 
    m [ " 11111 " ] = " insects " 
    m [ " 22222 " ] = " Brassica " 
    m [ " 33333 " ] = " small wind " 
    m [ " 44444 " ] = " little frog " 
    fmt.Println ( " m = " ,
    m) // Range traverse Map 
    for k, v := range m {
        fmt.Println("k=", k, "v=", v)
    }

    //复杂结构的map
    m1 := make(map[string]map[string]string)
    m1["aaaaa"] = make(map[string]string)
    m1["bbbbb"] = make(map[string]string)
    m1["aaaaa"]["11111"] = "小昆虫"
    m1["aaaaa"]["22222"] = "小白菜"
    m1["bbbbb"]["33333"] = "小东风"
    m1["bbbbb"]["44444"] = "小青蛙"
    fmt.Println("m1=", m1)
    for k1, v1 := range m1 {
        fmt.Println(k1, v1)
        for k2, v2 := range v1 {
            fmt.Println("", k2, v2)
        }
    }
}
