python實現日常記賬本小程式，python記賬本小程式

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、函數需要兩個檔案：一個類似錢包功能，存放錢；另一個用於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、程式還有改進處，例如將兩個檔案以參數的形式傳入，會簡化代碼。
