Python Extending a List

The extend() method of the list class increases the size of the list by appending the items in a given list.

Syntax

list.extend(x)

Parameters

x: an iterable to be appended to the original list

Return Value

The method doesn't return anything, as the list is extended in place.

Example

The following example demonstrates how you can extend a list −

lst = ['Bina', 'Arun', 'Bharat', 'Tim', 'Biplov']
print ("lst:", lst)
lst.extend(['Kiran', 'Sunil'])
print ("new list", lst)

It will produce the following output −

lst: ['Bina', 'Arun', 'Bharat', 'Tim', 'Biplov']
new list ['Bina', 'Arun', 'Bharat', 'Tim', 'Biplov', 'Kiran', 'Sunil']
