### go推荐写法 ~~~ func main() { age := show() fmt.Print(age) } func show() (result int) { result = 1000 return } ~~~ ### 多个返回值 ~~~ func main() { num1, num2, num3 := show() fmt.Print(num1, num2, num3) } func show() (int, int, int) { return 10, 20, 30 } ~~~ #### go推荐写法 ~~~ func main() { num1, num2, num3 := show() fmt.Print(num1, num2, num3) } func show() (a, b, c int) { a, b, c = 10, 20, 30 return } ~~~
