Return Multiple Values

Post Example

by yhuang Go fmt.Println fmt

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"

func vals() (int, int) {
    return 3, 7
}

func main() {
    a, b := vals()
    fmt.Println(a)
    fmt.Println(b)

    // If you only want a subset of the returned values, use the blank identifier _.
    _, c := vals()
    fmt.Println(c)
}
