Golang Lists

A list is a sequence of elements. Each element can be connected to another with a link in a forward or backward direction. The element can have other payload properties. 

This data structure is a basic type of container. Lists have a variable length and developers can remove or add elements more easily than an array. Data items within a list need not be contiguous in memory or on disk.

Golang Lists

To get started, a list can be used in Go, as shown in the following example; elements are added through the PushBack method on the list, which is in the container/list package:


package main

// importing fmt and container list packages
import (
	"container/list"
	"fmt"
)

// main method
func main() {
	var intList list.List
	intList.PushBack(11)
	intList.PushBack(23)
	intList.PushBack(34)

	for element := intList.Front(); element != nil; element = element.Next() {
		fmt.Println(element.Value.(int))
	}
}


The list is iterated through the for loop, and the element's value is accessed through the Value method.

Run the following commands:

go run list.go
11
23
34
