The append operator can be used to append values to the end of an array in Python. For example, let's say you have an array of fruit.
fruits = ["apple", "banana", "orange", "grapes"]
In this example, kiwi is appeneded to the end of the array.
You can loop through the array.
for x in fruits: print(x)
Kiwi will be included at the end of the array.
