What is the difference between Python's list methods append and extend?

The append method adds an item to the end of a list. The item can be of any type (integer, string, etc.).

The extend method adds all the items in an iterable (such as a list) to the end of the list.

Here's an example:

Add items to a list using the append method and extending the list with another list using the extend method in Python

The main difference between the two is that append adds a single item to the list, while extend adds all the items in an iterable to the list.
