python实现日常记账本小程序
python实现收支的自动计算，能够查询每笔账款的消费详情，具体内容如下
1、函数需要两个文件：一个类似钱包功能，存放钱；另一个用于记录每笔花销的用途
#!/usr/bin/envpython
importcPickleasp
withopen('wallet.data','w')asf:
p.dump(10000,f)
withopen('record.txt','w')asf:
pass
2、功能实现
#!!/usr/bin/envpython
#coding:utf8
importcPickleasp
importtime
date=time.strftime('%Y%m%d')
defsave_money():
sav_count=int(raw_input('savemoney:'))
sav_comment=raw_input('doingwhat:')
withopen('wallet.data')asf:
balance=p.load(f)
new_bal=balance+sav_count
withopen('wallet.data','w')asf:
p.dump(new_bal,f)
content='%-12s%-8s%-8s%-10s%-25s\n'%(date,'N/A',sav_count,new_bal,sav_comment)
withopen('record.txt','a')asf:
f.write(content)
defspend_money():
spe_count=int(raw_input('spendmoney:'))
spe_comment=raw_input('doingwhat:')
withopen('wallet.data')asf:
balance=p.load(f)
new_bal=balance-spe_count
withopen('wallet.data','w')asf:
p.dump(new_bal,f)
withopen('record.txt','a')asf:
content='%-12s%-8s%-8s%-10s%-25s\n'%(date,spe_count,'N/A',new_bal,spe_comment)
f.write(content)
defquery_info():
line='='*63
content='%s\n%-12s%-8s%-8s%-10s%-25s'%(line,'Date','Cost','Save','Balance','Comment')
withopen('wallet.data')asf:
new_bal=p.load(f)
print'newbalance:',new_bal
printcontent
withopen('record.txt')asf:
forlineinf:
printline
defshow_menu():
prompt='''''
'0':'spend_money'
'1':'save_money'
'2':'query_info'
'3':'quit'
'''
whileTrue:
CMDs={'0':spend_money,'1':save_money,'2':query_info}
choice=raw_input('whichdoyouwanttodo?%s:'%prompt)
ifchoicenotin'012':
break
CMDs[choice]()
if__name__=='__main__':
show_menu()
3、程序还有改进处，例如将两个文件以参数的形式传入，会简化代码。
