defer maybe not work as expected

When we use defer in for loop, defer maybe not work as expected.

Our code,

func main() {
	for i := 0; i < 10; i++ {
		fmt.Printf("number: %d\n", i)
		defer fmt.Printf("defer func\n")
	}

	fmt.Println("finish")
}

Our result,

go run main.go
number: 0
number: 1
number: 2
number: 3
number: 4
number: 5
number: 6
number: 7
number: 8
number: 9
finish
