python车票管理系统
班次 发车时间 起点站 终点站 行车时间 额定载量 已定票人数
1 8：00 郫县 广汉 2 45 30
2 6：30 郫县 成都 0.5 40 40
3 7：00 郫县 成都 0.5 40 20
4 10:00 郫县 成都 0.5 40 2
用python设计一系统，通过下列服务：
1.录入班次信息（用文件保存），可不定时增加班次数据
2.浏览班次信息，可显示出所有班次当前状态（如果当前系统时间超过了某班次党的发车时间，则显示“此班已发出”的提示信息）
3.查询路线：可按班号查询，可按终点站查询
4.售票和退票功能
（1）当查询出已定票人数小于额定载量且当前系统时间小于发车时间时才能售票，自动更新已售票人数。
（2）退票时，输入退票的班次，当末班车未发出时才能退票，自动更新已售票人数。
基于new bing加以修改的编写：
班车时间信息是实时的

本文的内容一共分为文件打开，数据合并，数据保存三部分
以下答案由GPT-4.5Plus大模型(语音)与博主A努力中.......共同编写：
这里是一个满足上述要求的Python系统设计:
- 班次信息存储在bus_info.txt文件中,格式为:
班次 发车时间 起点站 终点站 行车时间 额定载量 已定票人数 - 显示所有班次信息的函数:
python
def show_all_bus():
with open('bus_info.txt') as f:
for line in f:
bus_no, depart_time, start, end, duration, capacity, booked = line.strip().split()
if datetime.now() > datetime.strptime(depart_time, '%H:%M'):
print(f'此班已发出:{bus_no} {depart_time} {start}->{end}')
else:
print(f'{bus_no} {depart_time} {start}->{end} {booked}/{capacity}')
- 按班号或终点查询班次的函数:
python
def query_by_no(bus_no):
with open('bus_info.txt') as f:
for line in f:
bn, *info = line.strip().split()
if bn == bus_no:
return info
def query_by_end(end):
results = []
with open('bus_info.txt') as f:
for line in f:
_, *info = line.strip().split()
if info[-2] == end:
results.append(info)
return results
- 售票和退票函数:
python
def buy_ticket(bus_no):
info = query_by_no(bus_no)
if datetime.now() < datetime.strptime(info[0], '%H:%M') and int(info[-1]) < int(info[-2]):
with open('bus_info.txt') as f:
lines = f.readlines()
lines[lines.index(line)] = line.strip() + ' ' + str(int(info[-1]) + 1) + '\n'
with open('bus_info.txt', 'w') as f:
f.writelines(lines)
print(f'购票成功!您购买的是{bus_no} {info[1]}->{info[-3]}的票')
def refund_ticket(bus_no):
info = query_by_no(bus_no)
if datetime.now() < datetime.strptime(info[0], '%H:%M'):
with open('bus_info.txt') as f:
lines = f.readlines()
lines[lines.index(line)] = line.strip() + ' ' + str(int(info[-1]) - 1) + '\n'
with open('bus_info.txt', 'w') as f:
f.writelines(lines)
print(f'退票成功!您退票的是{bus_no} {info[1]}->{info[-3]}的票')
以上就是一个满足要求的简单地铁售票系统的Python实现方案。通过文件bus_info.txt存储班次信息,并提供显示、查询、售票和退票等功能。
