票务分配系统

下面是一个简单的票务分配系统的代码示例，该系统使用Python编程语言实现：

class Ticket:
    def __init__(self, id, name, price):
        self.id = id
        self.name = name
        self.price = price
        self.is_available = True

class TicketBookingSystem:
    def __init__(self):
        self.tickets = {}

    def add_ticket(self, ticket):
        self.tickets[ticket.id] = ticket

    def display_available_tickets(self):
        available_tickets = [ticket for ticket in self.tickets.values() if ticket.is_available]
        if not available_tickets:
            print("No tickets available.")
        else:
            for ticket in available_tickets:
                print(f"Ticket ID: {ticket.id}, Name: {ticket.name}, Price: {ticket.price}")

    def book_ticket(self, ticket_id):
        if ticket_id in self.tickets:
            ticket = self.tickets[ticket_id]
            if ticket.is_available:
                ticket.is_available = False
                print(f"Ticket with ID {ticket_id} has been booked.")
            else:
                print(f"Ticket with ID {ticket_id} is not available.")
        else:
            print(f"Ticket with ID {ticket_id} does not exist.")

# 创建票务分配系统对象
ticket_system = TicketBookingSystem()

# 添加票务
ticket1 = Ticket(1, "Concert Ticket", 100)
ticket_system.add_ticket(ticket1)

ticket2 = Ticket(2, "Movie Ticket", 50)
ticket_system.add_ticket(ticket2)

# 显示所有可用票务
ticket_system.display_available_tickets()

# 预订票务
ticket_system.book_ticket(1)
ticket_system.book_ticket(2)
ticket_system.book_ticket(3)

上述代码中，Ticket类表示一个票务对象，包含id、名称和价格等属性，以及一个表示票务是否可用的布尔值属性。TicketBookingSystem类表示票务分配系统，包含一个字典用于存储所有的票务对象。系统提供了添加票务、显示可用票务和预订票务等功能。在示例中，首先创建一个票务分配系统对象ticket_system，然后添加两个票务对象，并显示所有可用的票务。最后，尝试预订其中一些票务。
