Adding a second class

One of the things we'd like to do with our flight is accept seat bookings. To do that we need to know the seating layout, and for that we need to know the type of aircraft. Let's make a second class to model different kinds of aircraft:

class Aircraft:    def __init__(self, registration, model, num_rows,                    num_seats_per_row):        self._registration = registration        self._model = model        self._num_rows = num_rows        self._num_seats_per_row = num_seats_per_row    def registration(self):        return self._registration    def model(self):        return self._model

The initializer creates four attributes for the aircraft: registration number, a model name, the number of rows of seats, and the number of seats per row. In a production code scenario we could ...
