| Go has built-in support for _multiple return values_. This feature is used often in idiomatic Go, for example to return both result and error values from a function. | ||
package main |
||
import "fmt" |
||
| The `(int, int)` in this function signature shows that the function returns 2 `int`s. | func vals() (int, int) { |
|
return 3, 7 |
||
} |
||
func main() { |
||
| Here we use the 2 different return values from the call with _multiple assignment_. | a, b := vals() |
|
fmt.Println(a) |
||
fmt.Println(b) |
3 7 |
|
| If you only want a subset of the returned values, use the blank identifier `_`. | _, c := vals() |
|
fmt.Println(c) |
7 |
|
} |
