python火车订票管理系统

抱歉，我是一名语言模型AI，无法提供实时的火车订票管理系统，但是我可以给出一个简单的Python火车订票系统的伪代码，希望能够帮到你：

1.定义火车订票类

class TrainTicket:

def __init__(self, train_no, start_station, end_station, departure_time, arrival_time, price, seat_number):
self.train_no = train_no
self.start_station = start_station
self.end_station = end_station
self.departure_time = departure_time
self.arrival_time = arrival_time
self.price = price
self.seat_number = seat_number

2.定义火车订票系统函数

def train_booking_system():
ticket_list = []
while True:
print("欢迎使用火车订票系统：\n")
print("1.查询火车票信息")
print("2.订购火车票")
print("3.取消订单")
print("4.退出系统")
choice = input("请输入您的选项：")
if choice == "1":
train_no = input("请输入火车车次：")
for ticket in ticket_list:
if ticket.train_no == train_no:
print("车次：{}，起点站：{}，终点站：{}，出发时间：{}，到达时间：{}，票价：{}，余票数量：{}".format(ticket.train_no, ticket.start_station, ticket.end_station, ticket.departure_time, ticket.arrival_time, ticket.price, ticket.seat_number))
elif choice == "2":
train_no = input("请输入火车车次：")
for ticket in ticket_list:
if ticket.train_no == train_no:
seat_number = int(input("请输入购票数量："))
if seat_number > ticket.seat_number:
print("余票不足，请重新选择！")
else:
ticket.seat_number -= seat_number
print("订票成功，车次：{}，购票数量：{}，票价：{}，总价：{}".format(ticket.train_no, seat_number, ticket.price, ticket.price * seat_number))
elif choice == "3":
train_no = input("请输入火车车次：")
for ticket in ticket_list:
if ticket.train_no == train_no:
seat_number = int(input("请输入取消购票数量："))
if seat_number > (ticket.seat_number - seat_number):
print("取消购票数量超过已购票数，请重新选择！")
else:
ticket.seat_number += seat_number
print("取消购票成功，车次：{}，取消购票数量：{}，退款金额：{}".format(ticket.train_no, seat_number, ticket.price * seat_number))
elif choice == "4":
print("欢迎下次使用！")
break
else:
print("输入有误，请重新输入！")

3.测试火车订票系统

if __name__ == '__main__':
ticket1 = TrainTicket("G123", "北京", "上海", "08:00", "12:00", 500, 100)
ticket2 = TrainTicket("G234", "上海", "广州", "14:00", "18:00", 600, 80)
ticket3 = TrainTicket("G345", "广州", "深圳", "20:00", "22:00", 400, 120)
ticket_list = [ticket1, ticket2, ticket3]
train_booking_system()
