Regular expression – regular expression does not work in Go

var regex string = `^.+=0x[AF][AF]$`

Please forgive me for being an amateur of regular expressions, but I am really confused, why this is not a piece of code that does not work in Go

package main

import (
 "fmt"
 "regexp"
)

func main() {
 var a string = "parameter=0xFF"
 var regex string = "^.+=0x[AF][AF]$"
 result,err := regexp. MatchString(regex, a)
 fmt.Println(result, err)
}
// output: false 

This seems to work fine in python< /p>

import re

p = re.compile(r"^.+=0x[AF][AF]$")
m = p.match("parameter=0xFF")
if m is not None:
 print m.group()

// output: parameter=0xFF< /pre> 
What I want to do is to match whether the input format is  = 0x [AF] [AF]
 
Any help will be greatly appreciated
Have you tried using raw string literals (using back quotes instead of quotes)? 
Like this: 
 
 
var regex string = `^.+=0x[AF][AF]$`
