CodePudding user response：

You can space pad on the right with fmt.Sprintf("%-6s", "45")

You must do your own padding to pad with 0:

// Zero PAD Right
func zpadr(s string, n int) string {
    n -= len(s)
    if n > 0 {
        s  = strings.Repeat("0", n)
    }
    return s
}

Use like this: fmt.Sprintf("%s", zpadr("45", 6))
