Getenv retrieves the value of the environment variable named by the key. It returns the value, which will be empty if the variable is not present. To distinguish between an empty value and an unset value, use LookupEnv.

Go
Edit 
package main

import (
	"fmt"
	"os"
)

func main() {
	os.Setenv("NAME", "gopher")
	os.Setenv("BURROW", "/usr/gopher")

	fmt.Printf("%s lives in %s.\n", os.Getenv("NAME"), os.Getenv("BURROW"))
}
