示例代码：

package main

import (
	"fmt"
)

type Widget struct {
	id    int
	attrs []string
}

func main() {

	widgets := []Widget{
		Widget{
			id:    10,
			attrs: []string{"blah", "foo"},
		},
		Widget{
			id:    11,
			attrs: []string{"foo", "bar"},
		},
		Widget{
			id:    12,
			attrs: []string{"xyz"},
		},
	}

	for _, j := range widgets {
		fmt.Printf("%d ", j.id)
		for _, y := range j.attrs {
			fmt.Printf(" %s ", y)
		}
		fmt.Println()
	}
}

输出：

10  blah  foo 
11  foo  bar
12  xyz
