这里有一个问题，是关于go语言的一个疑问?

Question

package mainimport ("fmt")type people struct{name stringage uintsex bool}type Ipeople interface{get() peopleshow_name()show_age()show_sex()}func(this people)show_name(){fmt.Println(this.name)}func(this people)show_age(){fmt.Println(this.age)}func(this people)show_sex(){fmt.Println(this.sex)}func(this people)get() people{return this}func main(){var interf Ipeople = people{"asdf",18,true}interf.show_name()fmt.Println(interf.(people))}这最后一句中的interf.(people)是什么意思??接口调用匿名函数？大佬求教！

Answer 1

表示接口interf指向的实例对象是不是people类型
