How to get the last element of a slice in Go?

Question

What is the Go way for extracting the last element of a slice?
var slice []int

slice = append(slice, 2)
slice = append(slice, 7)

slice[len(slice)-1:][0] // Retrieves the last element

The solution above works, but seems awkward.

For just reading the last element of a slice: sl[len(sl)-1] For removing it: sl = sl[:len(sl)-1] package main import ( "fmt" ) func main() { sl := []int{1, 2, 3, 4, 5} fmt.Println(sl[len(sl)-1]) // last element fmt.Println(sl[len(sl)-1:]) // slice of last element fmt.Println(sl[len(sl)-1 : len(sl)]) // same as above } https://play.golang.org/p/kcThrqa-64c See this page about slice tricks
