如何在Golang中使用for循环在struct中存储值

I want to store values in a struct. I have multiple set of datas and while iterating those set of data, I have to store those sets into struct. I should also have the previous stored data along with the currently stored.

Please find the code i am using

    package main
    import (
      "fmt"
    )

    type saveDetails struct {
      ID string
      Grade string
      Regular string
      OpeningKey string
    }

    func main() {
       tagsList := []saveDetails {}
       results = [{ {1000000001 A Regular JOBOp123}} { {1000000002 B Regular JOBOp234}} { {1000000003 C  Regular JOBOp456}}]

       for _, details := range results {
          tagsList = append(tagsList, saveDetails {ID: details.ID, Grade:details.Grade, Regular:details.Regular, OpeningKey:details.OpeningKey})
       }
       fmt.Println("saveDetails :",tagsList )
     }

Please help me in resolving this issue. I am new to this array and structs in golang. I am not sure whether i could use the append function. It could be very much helpful if i get an working code.
