# Python Program to Insert element at end of array(list)

In this tutorial, we will learn writing the python program to insert an element at the end of an array (list in case of python) and print the array (list) after insertion as output.

## Problem Statement

Our problem statement is we have to add an element given by the user, at the end of the given array (list).

For example:

Case 1: if the given array (list) is [1, 2, 3, 4] and the users give input 9 to add at last.

The output should be [1, 2, 3, 4, 9].

Case 2: if the given array (list) is [9, 2, 4, 8] and the users give input 10 to add at last.

The output should be [9, 2, 4, 8, 10].

## Our logic to add an element in the array(list)

• Our program will take input from the user.
• Then, use append() built-in function with the user input as an argument. It will add the element at the end and print the output.

## Algorithm to add an element in the array(list)

Step 1: Start

Step 2: take an input from the user

Step 3: use append() and prints the array (list).

Step 4: Stop

## Add Element at End of Array(list)

### 1). Using append() Method

``````arr = [1,2,3,4,5]
num=int(input("Enter a number to insert in array at end :"))
# adding element at the end of the array(list)
arr.append(num)
print("Array after inserting",num,"at end",arr)``````

Output

```Enter a number to insert in array at end :6
Array after inserting 6 at end [1, 2, 3, 4, 5, 6]```

Explanation:

For the given array (list) [1, 2, 3, 4, 5], the user inputs element 6 to add at the end of the array (list). using the append() method, our program will easily add element 6 at the end of the list and returns the updated list.

### 2). Using the insert() Method

While insert() is generally used to add an element at a specific position, you can also use it to insert an element at the end by specifying the position as the length of the list.

``````arr = [1,2,3,4,5]
num=int(input("Enter a number to insert in array at end :"))
# adding element at the end of the array(list)
arr.insert(len(arr), num)
print("Array after inserting",num,"at end",arr)``````

Output

```Enter a number to insert in array at end :6
Array after inserting 6 at end [1, 2, 3, 4, 5, 6]```

### 3). Using the + Operator

You can use the `+` operator to concatenate another list containing your element to the original list.

``````arr = [1,2,3,4,5]
num=int(input("Enter a number to insert in array at end :"))
# adding element at the end of the array(list)
arr += [num]
print("Array after inserting",num,"at end",arr)``````

Output

```Enter a number to insert in array at end :6
Array after inserting 6 at end [1, 2, 3, 4, 5, 6]```
