is it necessary to create the add_to_list function
is creating the function add_to_list is important because the jobe can be done without it, or this is considered a professional thing?
It is not necessary, but it is very good practice. If you didn't use functions and used that block of code several times in your app, then if you needed to change something then you would need to do the same thing several times. Functions also make reading your code much easier. That is ideal especially if other developers are using your code. Hope this helps. :)
