手动关联和参数化操作，添加对座位类型（First头等/Business商务/Coach经济）的随机选择以及对不同客机编号及机票价格的随机选择（见下图）。运行时设置不变，运行回放脚本(脚本无错误，参数值替换正常)，利用行程菜单“Itinerary”查看所订座位类型以及客机编号和价格

手动关联和参数化操作通常是指在程序设计中，将特定的行为或数据与输入参数关联起来，以便在运行时根据不同的参数值动态地执行不同的任务。在这个场景中，你可以创建一个函数或者类方法，它接受座位类型、客机编号和机票价格作为输入参数。例如：

class FlightBooking:
    def __init__(self, seat_type, flight_number, ticket_price):
        self.seat_type = seat_type
        self.flight_number = flight_number
        self.ticket_price = ticket_price

    def book_ticket(self):
        print(f"Booked {self.seat_type} seat on Flight {self.flight_number} with a price of {self.ticket_price}")

def random_booking():
    seat_types = ["First", "Business", "Coach"]
    flight_numbers = range(1001, 1010)  # 示例，实际应从数据库获取
    prices = [random.randint(500, 5000) for _ in seat_types]  # 随机价格范围

    seat_type = seat_types[random.randint(0, len(seat_types) - 1)]
    flight_number = random.choice(flight_numbers)
    ticket_price = prices[seat_types.index(seat_type)]

    booking = FlightBooking(seat_type, flight_number, ticket_price)
    booking.book_ticket()

# 替换`random_booking()`中的参数
run_playback_script(random_booking)

# 查看行程信息
def view_itinerary(booked_flight):
    print("Itinerary:")
    print(f"Seat Type: {booked_flight.seat_type}")
    print(f"Flight Number: {booked_flight.flight_number}")
    print(f"Ticket Price: {booked_flight.ticket_price}")

view_itinerary(random_booking())  # 运行时显示预定的座位信息
