flat is better than nested. You can write both if statements into a singleifwith anand(or its equivalent in go language. wait, why am i here? goes back to python), and then you just have 1 if statement left. Also, in this example, you can return the port value early as well for the same effect.

I'll avoid using if which includes an optional statement:
if statement; condition
and using simple if with:
func GetPortFromEnvironment(name string, defaultPort int32) int32
env := os.Getenv("SERVICE_PORT")
// no env value. return defaultPort
if env == ""
return defaultPort
// there's env value.
port, err := strconv.ParseInt(env, 10, 32)
if err != nil
// Unable to parse port. Fallback to default.
return defaultPort
return int32(port)
