The code below extends the Bookings class by adding a method which, for a given reservation ID, will set the party complete value to 1 or 0 if a party becomes complete or incomplete. The code below creates a number of bookings, assigns each with an initial completeness status, and checks the completeness status of one of them, then changes its completeness status, and checks it again. class BookingsExtended(Bookings): ""Extends the class Bookings to include a party_complete status. "n" def set_completeness(self, reservation_ID: int, party_complete: int) -> None: "n"Set the party_complete to complete (1) or incomplete (0).
