import ( "container/list" "fmt" ) func main() { mylist := list.New() mylist.PushBack("apple") mylist.PushBack("banana") mylist.PushBack("orange") fmt.Println("Length of list: ", mylist.Len()) }In this example, we create a new list using the `list.New()` method, add three elements to the list using `PushBack()`, and then get the length of the list using `Len()` which returns 3. Overall, the `Len()` method is a convenient way to get the size of a container list in Go without having to manually count the number of elements. It's part of the standard `container/list` package in Go.
