像Ruby这样的golang中的语法糖方法

Question

We have * in ruby, if we used it with string like

"a" * 3
 => "aaa" 

it will generate the string with the multiplier length.

I want to do same in Go but couldn't get success. I am trying to ignore to make a custom method as I need a random string with specified length in testing.

Anyone knows about it?

Thanks

I have tried to go through some documents but did not get any short hand method and I am trying to avoid writing a function.

In ruby:

"a" * 3
 => "aaa"

Check https://golang.org/pkg/strings/#Repeat

From the godoc:

func main() {
    fmt.Println("ba" + strings.Repeat("na", 2))
}
// banana
