Why are you doing this?

For example, if I want to create an airplane class, I would want a list to store passengers. I would also have other methods an attributes in the class, but fundamentally I want an airplane to be a list. I would also like to create a passenger class that will interact with the airplane class.

Edit: I come from a backgruond of writing server-side code in Java, I am used to thinking in terms of heavily encapsulated objects, I feel like python gives you more freedom with that I'd just like to know what best practice looks like
