How to add variable to string variable in golang

Question

I'm trying to add a value to a variable string in golang, without use printf because I'm using revel framework and this is for a web enviroment instead of console, this is the case:

data := 14 response := `Variable string content` 

so I can't get variable data inside variable response, like this

response := `Variable string 14 content` 

Any idea?

Answer 1

Why not use fmt.Sprintf?

data := 14 response := fmt.Sprintf("Variable string %d content", data) 

Answer 2

I believe that the accepted answer is already the best practice one. Just like to give an alternative option based on @Ari Pratomo answer:

package main  import (     "fmt"     "strconv" )  func main() {     data := 14     response := "Variable string " + strconv.Itoa(data) + " content"     fmt.Println(response) //Output: Variable string 14 content }  

It using strconv.Itoa() to convert an integer to string, so it can be concatenated with the rest of strings.
