strconv.Unquote()

The Unquote() function is an inbuilt function of the strconv package which is used to interpret the given string s as a single-quoted, double-quoted, or backquoted,  and returns the string value that s quotes. (If there is a single-quoted string, the function returns the corresponding one-character string.)

It accepts a parameter (s) and returns the string value that s quotes.

Syntax:

func Unquote(s string) (string, error)

Parameter(s):

• s : The quoted string value from which we have to get the string.

Return Value:

The return type of the Unquote() function is a (string, error), it returns the string value that the given string (s) quotes.

Example 1:

// Golang program to demonstrate the
// example of strconv.Unquote() Function

package main

import (
	"fmt"
	"strconv"
)

func main() {
	fmt.Println(strconv.Unquote("Hello, world! How are you?"))
	fmt.Println(strconv.Unquote("\"Hello, world! How are you?\""))
	fmt.Println(strconv.Unquote("`Hello, world! How are you?`"))
	fmt.Println(strconv.Unquote("'\u2639'"))
}

Output:

 invalid syntax
Hello, world! How are you? <nil>
Hello, world! How are you? <nil>
☹ <nil>

Example 2:

// Golang program to demonstrate the
// example of strconv.Unquote() Function

package main

import (
	"fmt"
	"strconv"
)

func main() {
	str, err := strconv.Unquote("Hello, world!")
	fmt.Printf("%q, %v\n", str, err)

	str, err = strconv.Unquote("\"Hello, world!\"")
	fmt.Printf("%q, %v\n", str, err)

	str, err = strconv.Unquote("`Hello, world!`")
	fmt.Printf("%q, %v\n", str, err)

	str, err = strconv.Unquote("'\u263a'")
	fmt.Printf("%q, %v\n", str, err)

	str, err = strconv.Unquote("'\u2639\u2639'")
	fmt.Printf("%q, %v\n", str, err)
}

Output:

"", invalid syntax
"Hello, world!", <nil>
"Hello, world!", <nil>
"☺", <nil>
"", invalid syntax
