python實現收支的自動計算，能夠查詢每筆賬款的消費詳情，具體內容如下
1、函數需要兩個文件：一個類似錢包功能，存放錢；另一個用于記錄每筆花銷的用途
#!/usr/bin/env python
import cPickle as p
with open('wallet.data','w') as f:
p.dump(10000,f)
with open('record.txt','w') as f:
pass
2、功能實現
#!!/usr/bin/env python
#coding:utf8
import cPickle as p
import time
date = time.strftime('%Y%m%d')
def save_money():
sav_count=int(raw_input('save money: '))
sav_comment = raw_input('doing what: ')
with open('wallet.data') as f:
balance = p.load(f)
new_bal = balance + sav_count
with open('wallet.data','w') as f:
p.dump(new_bal,f)
content = '%-12s%-8s%-8s%-10s%-25s\n'%(date,'N/A',sav_count,new_bal,sav_comment)
with open('record.txt','a')as f:
f.write(content)
def spend_money():
spe_count=int(raw_input('spend money: '))
spe_comment = raw_input('doing what: ')
with open('wallet.data') as f:
balance = p.load(f)
new_bal = balance - spe_count
with open('wallet.data','w') as f:
p.dump(new_bal,f)
with open('record.txt','a')as f:
content = '%-12s%-8s%-8s%-10s%-25s\n'%(date,spe_count,'N/A',new_bal,spe_comment)
f.write(content)
def query_info():
line = '='*63
content = '%s\n%-12s%-8s%-8s%-10s%-25s'%(line,'Date','Cost','Save','Balance','Comment')
with open('wallet.data') as f:
new_bal = p.load(f)
print 'new balance: ',new_bal
print content
with open('record.txt') as f:
for line in f:
print line
def show_menu():
prompt = '''''
'0':'spend_money'
'1':'save_money'
'2':'query_info'
'3':'quit'
'''
while True:
CMDs={'0':spend_money,'1':save_money,'2':query_info}
choice = raw_input('which do you want to do ?%s: '%prompt)
if choice not in '012':
break
CMDs[choice]()
if __name__=='__main__':
show_menu()
3、程序還有改進處，例如將兩個文件以參數的形式傳入，會簡化代碼。
