I'm a total newbie to Python and I decided to learn by building an app and picking up concepts along the way. I decided to make an app where you can view a catalog of plane flights. Once you click on one, a new screen appears where you can view a map of the plane, click on specific seat(s), and then the seat details will pop up on a sidebar.

Right now, I'm looking for someone to critique my code, and if possible, help me to switch frames (from catalog to seat map). Thanks!
