下面的代碼沒有按預(yù)期工作。package mainimport "fmt"func main() { questions := make(map[int]interface{}) questions[1] = map[interface{}]string{ "q1": "This is Question - 1?", "op1": "This is Option - 1", "op2": "This is Option - 2", true: "This is Option - 1", } // This give map[interface {}]string fmt.Printf("%T \n", questions[1]) // This not working for key, val := range questions[1] { printf("%v : %v", key, val) }}遍及地圖的 for 循環(huán)不起作用。Go 編譯器給出錯誤“無法范圍覆蓋問題 [1]（類型接口 {}）”

讓去理解questions[1]有類型是map
for key, val := range questions[1].(map[interface{}]string) {
fmt.Printf("%v : %v\n", key, val)
