How to convert interface{} to string?

I\'m using docopt to parse command-line arguments. This works, and it results in a map, such as

map[:www.google.de :80 --help:false --ver

You don't need to use a type assertion, instead just use the %v format specifier with Sprintf:

hostAndPort := fmt.Sprintf("%v:%v", arguments[""], arguments[""])
