python实现日常记账本小程序 实现日常记账本小程序 主要为大家详细介绍了python实现日常记账本小程序，具有一定的参考价值，感兴趣的小伙伴们可以参考一下 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/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、功能实现 #!!/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。 以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持我们。
