代码一、车票（车次编号、起点站、终点站、发车时间、到达时间、价格、剩余票数）查询 1、站站查询 2、车次查询

ChatGPT: 您好，以下是车票查询的代码：

class Train:
    def __init__(self, train_no, start_station, end_station, departure_time, arrival_time, price, remaining_tickets):
        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.remaining_tickets = remaining_tickets

class TrainTicketSystem:
    def __init__(self):
        self.trains = []

    def add_train(self, train):
        self.trains.append(train)

    def search_by_station(self, start_station, end_station):
        result = []
        for train in self.trains:
            if train.start_station == start_station and train.end_station == end_station:
                result.append(train)
        return result

    def search_by_train_no(self, train_no):
        for train in self.trains:
            if train.train_no == train_no:
                return train
        return None

您可以通过创建 Train 对象并将其添加到 TrainTicketSystem 中来添加车次信息。search_by_station 方法可以通过起点站和终点站查询车次信息，search_by_train_no 方法可以通过车次编号查询车次信息。
