Question

I want to create string \\"str\\" but i want to give variable name to str. For ex : x := "name" q := fmt.Sprintf("\\"%s\\"", x) I want q = "\\"name\\""

I tried this

Answer 1

Use escape sequences preceded by \\ to show literal special characters in a formatted string \\\\ for \\ and \\" for "

package main

import (
    "fmt"
)

func main() {
    x := "hello"
    q := fmt.Sprintf("\\\"%s\"\\", x)
    fmt.Println(q)
}

Answer 2

A more functional, flexible solution, depending on your taste:

x := "hello"
p := []byte{'"', '\\', '"', '"'}
q := append(append(p, []byte(x)...), p...)
fmt.Printf("%s", q)
