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.
Example
currencies = ['Dollar', 'Euro', 'Pound']
# append 'Yen' to the list
currencies.append('Yen')
print(currencies)
# Output: ['Dollar', 'Euro', 'Pound', 'Yen']
1. Syntax of List append()
The syntax of the append() method is:
list.append(item)
2. append() Parameters
The method takes a single argument
- item – an item (number, string, list etc.) to be added at the end of the list
3. Return Value from append()
The method doesn’t return any value (returns None).
4. 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']
5. 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.
