You can use lists whenever you need to keep several things somewhere. Maybe you want to sort them, of shuffle them up, or reverse the order. With lists you can do all of that. I've written a typing trainer that modifies a list of words the way you say (for example all words with q in it or whatever) and feeds them to you. I've written a calory calculator that stores several food items with their calories and other values in a list. You can add more foods or delete them. I've written a learning aid, that works over a list with 'study cards' that have a question and an answer and some other info. The list gets shuffled up and presented for you to learn. There are uncountable use cases really, and while learning more, you'll probably come up with some of your own.

Another example of the usefulness of lists is to retain a series of results which may occur throughout a code, then being able to retrieve a specific result from the list to use again.

Hello my friend, well this is a data structure very usefull, and you can use this specially when you want yo store several values for any purpose, but you have to be careful with the quantity of values because lists are all little bit slower, if you want to store many many data, you probably should use the numpy lists

I can't tell you the utility : discover it by yourself while practicing. Then you will understand how useful are lists.

List is a collection which is ordered and changeable and indexed. Allows duplicate members.

Generally lists are used on roster pages, such as greatest to least. Or perhaps if you want to get fancy, your grocery list. There are many places lists are used, but the intention is purely situational.
