Answer with Explanation

In this tutorial, we will learn about the Python list append() method with the help of examples.

The append() method adds an item to the end of the list. 


currencies = ['Dollar', 'Euro', 'Pound']

# append 'Yen' to the list
currencies.append('Yen')

print(currencies)

# Output: ['Dollar', 'Euro', 'Pound', 'Yen']

Syntax of List append()

The syntax of the append() method is: 


 list.append(item)

append() Parameters

The method takes a single argument

item - an item (number, string, list etc.) to be added at the end of the list.

The method doesn't return any value (returns None).

Example 1: Adding Element to a List 


 # animals list
animals = ['cat', 'dog', 'rabbit']

# Add 'guinea pig' to the list
animals.append('guinea pig')

print('Updated animals list: ', animals)

Output


 Updated animals list:  ['cat', 'dog', 'rabbit', 'guinea pig']

Example 2: Adding List to a List 


 # animals list
animals = ['cat', 'dog', 'rabbit']

# list of wild animals
wild_animals = ['tiger', 'fox']

# appending wild_animals list to animals
animals.append(wild_animals)

print('Updated animals list: ', animals)

Output 


Updated animals list:  ['cat', 'dog', 'rabbit', ['tiger', 'fox']]

In the program, a single item (wild_animals list) is added to the animals list.
