How to append element in the list

Python provides built-in methods to append or add elements to the list. We can also append a list into another list. These methods are given below.

  • append(elmt) - It appends the value at the end of the list.
  • insert(index, elmt) - It inserts the value at the specified index position.
  • extends(iterable) - It extends the list by adding the iterable object.

Let's understand these methods by the following example.

1. append(elmt)

This function is used to add the element at the end of the list. The example is given below.

Example -

Output:

Current names List is: ['Joseph', 'Peter', 'Cook', 'Tim']
Please enter a name:
Devansh
Updated name List is: ['Joseph', 'Peter', 'Cook', 'Tim', 'Devansh']

2. insert(index, elmt)

The insert() function adds the elements at the given an index position. It is beneficial when we want to insert element at a specific position. The example is given below.

Example -

Output:

Current Numbers List:  [10, 20, 30, 40, 50]
The new list is:  [10, 20, 30, 77, 40, 50]
enter a number to add to list:
 45
enter the index to add the number:
1
Updated Numbers List: [10, 45, 20, 30, 77, 40, 50]

3. extend(iterable)

The extends() function is used to add the iterable elements to the list. It accepts iterable object as an argument. Below is the example of adding iterable element.

Example -

Output:

[10, 20, 30, '52.10', '43.12']
[10, 20, 30, '52.10', '43.12', 40, 30]
[10, 20, 30, '52.10', '43.12', 40, 30, 'A', 'p', 'p', 'l', 'e']
