How to split a string and assign it to variables in Golang?

Question

In Python it is possible to split a string and assign it to variables:
ip, port = '127.0.0.1:5432'.split(':')

but in Golang it does not seem to work:
ip, port := strings.Split("127.0.0.1:5432", ":") // assignment count mismatch: 2 = 1

Question: How to split a string and assign values in one step?

Two steps, for example, package main import ( "fmt" "strings" ) func main() { s := strings.Split("127.0.0.1:5432", ":") ip, port := s[0], s[1] fmt.Println(ip, port) } Output: 127.0.0.1 5432 One step, for example, package main import ( "fmt" "net" ) func main() { host, port, err := net.SplitHostPort("127.0.0.1:5432") fmt.Println(host, port, err) } Output: 127.0.0.1 5432 <nil>
