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:

fruits = ['apple', 'banana', 'mango']

# Append an item to the list
print(fruits)  # ['apple', 'banana', 'mango', 'orange']

# Extend the list with another list
fruits.extend(['strawberry', 'kiwi'])
print(fruits)  # ['apple', 'banana', 'mango', 'orange', 'strawberry', 'kiwi']

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.
