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 strftimeimport pickleimport ostry: 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
