How to Loop Over a Python List Using the Index Numbers?
The primary benefit of using a Python list as opposed to subscripts is that you can easily loop over it. So if you have a list of 10, 20 or 1000 items, you generally don't need to write that many different lines of code. In other words, there's a powerful built-in functionality in Python waiting to be used.

As you loop over each element, you can perform operations on the item. This is great for when you need to work with every element in a list.
