List append list Python

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.
