Part (f) [3 MARKS] Complete method change-planes in class Flight: def change-planes(self, other_airplane): (Flight, Airplane) -> bool If other airplane has enough seats to hold the passengers on this flight, use other airplane for this flight. Whether or not we change to other_airplane, return the number of available seats on this flight (seats not currently occupied by passengers). >>> a1 = Airplane ('Boeing 747', '19643', 366, 45267.7) >>> f = Flight(a) >>> f.add('Myrto') True >>> f.add('Jen' True >>> a2 = Airplane ('Bombardier Dash 8', '11234', 39, 6444.6) >>> f.change-planes (a2) >>> a3 = Airplane('Cessna 150E', '9378', 1, 824.8) >>> f.change-planes (a3) 37

Part (d) [2 MARKS] Complete method __init__ in class Flight: def __init__(self, plane): (Flight, Airplane) -> None Type Create a Flight with an empty passenger list on airplane plane. >>> a = Airplane ('Boeing 747', '19643', 366, 45267.7) >>> f = Flight(a) >>> str(f.airplane) 'Airplane (Boeing 747, 19643, 366, 45267.7) >>>> f.passengers

Part (e) [3 MARKS] Complete method add in class Flight. def add(self, passenger): (Flight, str) -> bool If there are still seats available on this flight, add passenger to the passenger list.
