飞机订票系统简易代码

飞机订票系统是一个用于管理航班信息和乘客订票的系统。下面是一个简易的飞机订票系统的代码示例：

class Flight:
    def __init__(self, flight_number, departure, destination, date, capacity):
        self.flight_number = flight_number
        self.departure = departure
        self.destination = destination
        self.date = date
        self.capacity = capacity
        self.passengers = []

    def add_passenger(self, passenger):
        if len(self.passengers) < self.capacity:
            self.passengers.append(passenger)
            print(f"Passenger {passenger} added to flight {self.flight_number}")
        else:
            print(f"Flight {self.flight_number} is already full")

    def get_available_seats(self):
        return self.capacity - len(self.passengers)


class BookingSystem:
    def __init__(self):
        self.flights = {}

    def add_flight(self, flight):
        self.flights[flight.flight_number] = flight

    def book_ticket(self, flight_number, passenger):
        if flight_number in self.flights:
            flight = self.flights[flight_number]
            if flight.get_available_seats() > 0:
                flight.add_passenger(passenger)
            else:
                print(f"No available seats on flight {flight_number}")
        else:
            print(f"Flight {flight_number} does not exist")


# 创建航班
flight1 = Flight("F001", "Beijing", "Shanghai", "2022-01-01", 100)
flight2 = Flight("F002", "Shanghai", "Beijing", "2022-01-02", 150)

# 创建订票系统
booking_system = BookingSystem()

# 添加航班到订票系统
booking_system.add_flight(flight1)
booking_system.add_flight(flight2)

# 订票
booking_system.book_ticket("F001", "Passenger A")
booking_system.book_ticket("F001", "Passenger B")
booking_system.book_ticket("F001", "Passenger C")
booking_system.book_ticket("F001", "Passenger D")
booking_system.book_ticket("F001", "Passenger E")

booking_system.book_ticket("F002", "Passenger F")
booking_system.book_ticket("F002", "Passenger G")
booking_system.book_ticket("F002", "Passenger H")

# 输出航班信息
print(f"Flight {flight1.flight_number} has {flight1.get_available_seats()} available seats")
print(f"Flight {flight2.flight_number} has {flight2.get_available_seats()} available seats")

这个简易的飞机订票系统代码示例包含了两个类：`Flight`和`BookingSystem`。`Flight`类表示一个航班，包含航班号、出发地、目的地、日期和容量等属性，以及添加乘客和获取可用座位数的方法。`BookingSystem`类表示订票系统，包含一个航班字典，可以添加航班和订票功能。
