Arbitrary data type slicing Golang

This is a creation in Article, where the information may have evolved or changed.

Package Mainimport ("FMT". "StrConv") type Element interface{}type List []elementtype person struct {name Stringage  int}func (P-person) String () s Tring {return ' my name is ' + P.name + "My age is" + Itoa (p.age)}var slice_1 = []string{"Hello"}var map_1 = Map[string]s tring{' city ': ' Beijing ', ' name ': ' CS ', ' from ': ' USA '}func main () {list: = Make (list, 5) list[0] = 1                    //an intlist[1] = "Hello"              //a stringlist[2] = person{"Barry", +//structlist[3] = slice_1              //a slicelist[4] = map_1                //A MA Pfor _, Element: = Range List {switch v:=element. Type) {//v is a specific value object, and element is the interface object case int:fmt. Println (element, ", int") Case string:fmt. Println (Element, ", string") Case person:fmt.

The general slice can only hold one data type, but with the interface can be highly abstracted, so that the slice stored data type arbitrary!

Here is an example.
