Python List append()

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

Example

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

Return Value from append()

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.

Note: If you need to add items of a list (rather than the list itself) to another list, use the extend() method.
