python编写一个会算账的脚本的示例代码编写一个会算账的脚本的示例代码
python算账脚本算账脚本
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('[35m%Y-%m-%d[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('[35m%Y-%m-%d[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('[34m%-20s%-9s%-9s%-10s%-18s[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('[35m%Y-%m-%d 33[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('[32msee you3[0m')
break
cmds[choice]()
if __name__ == '__main__':
choice_memu()
except KeyboardInterrupt:
print('[32msee you3[0m')
except ValueError:
print('[31minvalid inputs[0m')
3.与上面的表格比较发现结果一样
