python算账脚本

1.假如小明卡里有10000元去商场买东西发现钱不够又向父母借了5000账单如下

2.以下脚本就能实现上面的运算

from time import strftime
import pickle
import os
try:
 def save():
  data = strftime('\033[35m%Y-%m-%d\033[0m')
  money = int(input('How much do you have to save?:'))
  comment = input('Which come of money?')
  with open('account.book','rb') as fname:
    list = pickle.load(fname)
    record = list[-1][-2]
    balance = record + money
    list.append([data,money,0,balance,comment])
    with open('account.book','wb') as fname:
      pickle.dump(list,fname)
 def cost():
 data = strftime('\033[35m%Y-%m-%d\033[0m')
 money = int(input('How much did you spend?:'))
 comment = input('Where is it used?:')
 with open('account.book','rb') as fname:
   list = pickle.load(fname)
   record = list[-1][-2]
   balance = record - money
   list.append([data,0,money,balance,comment])
   with open('account.book', 'wb') as fname:
     pickle.dump(list, fname)
 def query():
 print('\033[34m%-20s%-9s%-9s%-10s%-18s\033[0m' % ('date','save','cost','balance','comment'))
 with open('account.book','rb') as fname:
   record = pickle.load(fname)
   for i in record:
     print('%-29s%-9s%-9s%-10s%-20s' % tuple(i))
 def choice_memu():
  promat='''
  (0)save
  (1)cost
  (2)query
  (3)exit
  please choice:'''
  fname = 'account.book'
  if not os.path.exists(fname):
    with open(fname,'wb') as obj:
     t_t = strftime('\033[35m%Y-%m-%d\033[0m')
     data = [[t_t,0,0,10000,'int']]
     pickle.dump(data,obj)
  while 1:
    cmds = {'0':save,'1':cost,'2':query}
    choice = input(promat)
    if choice not in ['0','1','2','3']:
      continue
    if choice == '3':
      print('\033[32msee you\033[0m')
      break
    cmds[choice]()
 if __name__ == '__main__':
  choice_memu()
except KeyboardInterrupt:
  print('\033[32msee you\033[0m')
except ValueError:
  print('\033[31minvalid inputs\033[0m')

3.与上面的表格比较发现结果一样
