python机票订购系统

好的，一个简单的机票订购系统可以包含以下功能：

1. 用户注册和登录功能
2. 显示机票信息，包括航班号、航班日期、起飞时间、到达时间、出发地、目的地和票价等信息
3. 用户选择航班、座位类型和数量
4. 用户填写个人信息和联系方式
5. 用户确认订单并完成支付

下面是一个简单的示例代码，你可以参考一下：

import random

class Flight:
    def __init__(self, number, date, departure, arrival, departure_time, arrival_time, price):
        self.number = number
        self.date = date
        self.departure = departure
        self.arrival = arrival
        self.departure_time = departure_time
        self.arrival_time = arrival_time
        self.price = price
        self.seats = {'Economy': 100, 'Business': 20, 'First Class': 5}
    
    def display_info(self):
        print('Flight Number:', self.number)
        print('Date:', self.date)
        print('Departure:', self.departure)
        print('Arrival:', self.arrival)
        print('Departure Time:', self.departure_time)
        print('Arrival Time:', self.arrival_time)
        print('Price:', self.price)
        print('Available Seats:')
        for seat_type, num_seats in self.seats.items():
            print(seat_type, ':', num_seats)
    
    def book_ticket(self, seat_type, num_tickets):
        if seat_type not in self.seats:
            print('Invalid seat type.')
            return False
        if self.seats[seat_type] < num_tickets:
            print('Not enough seats available.')
            return False
        self.seats[seat_type] -= num_tickets
        return True

class User:
    def __init__(self, name, email, phone):
        self.name = name
        self.email = email
        self.phone = phone
    
    def display_info(self):
        print('Name:', self.name)
        print('Email:', self.email)
        print('Phone:', self.phone)

class BookingSystem:
    def __init__(self):
        self.flights = []
        self.users = []
        self.bookings = {}
    
    def add_flight(self, flight):
        self.flights.append(flight)
    
    def display_flights(self):
        for flight in self.flights:
            flight.display_info()
    
    def register_user(self, name, email, phone):
        user = User(name, email, phone)
        self.users.append(user)
        return user
    
    def login(self, email):
        for user in self.users:
            if user.email == email:
                return user
        return None
    
    def book_ticket(self, user, flight, seat_type, num_tickets):
        if flight.book_ticket(seat_type, num_tickets):
            booking_id = random.randint(1000, 9999)
            while booking_id in self.bookings:
                booking_id = random.randint(1000, 9999)
            self.bookings[booking_id] = {'user': user, 'flight': flight, 'seat_type': seat_type, 'num_tickets': num_tickets}
            return booking_id
        else:
            return None
    
    def display_booking_info(self, booking_id):
        if booking_id in self.bookings:
            booking = self.bookings[booking_id]
            booking['user'].display_info()
            booking['flight'].display_info()
            print('Seat Type:', booking['seat_type'])
            print('Number of Tickets:', booking['num_tickets'])
        else:
            print('Invalid Booking ID.')

这个代码中包含了三个类：Flight、User 和 BookingSystem。Flight 类存储航班信息和座位信息，User 类存储用户信息，BookingSystem 类处理用户操作，包括添加航班、注册用户、登录、预订机票和显示订单信息等。你可以根据实际需求对代码进行修改和扩展。
