python算賬腳本

1.假如小明卡里有10000元去商場買東西發現錢不夠又向父母借了5000賬單如下

2.以下腳本就能實現上面的運算

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.與上面的表格比較發現結果一樣
