tutorial: understanding and using the extend() function in python lists
in python, lists are versatile data structures that allow you to store and manipulate collections of items. one of the built-in methods for lists is extend(), which is used to add multiple elements to the end of an existing list. this tutorial will explain how the extend() function works, its syntax, and provide examples to illustrate its usage.
understanding the extend() function:
the extend() function in python is used to append elements from an iterable (such as a list, tuple, set, or another iterable object) to the end of an existing list. it modifies the original list in place and does not return a new list. this means that the original list is updated with the additional elements.
