Python写的ATM小程序

准备好好学学Python了，要不快没饭吃了，这两个礼拜看了一些视频教程和书籍，遂拿这个ATM小程序练练手。文件结构：程序共有6个py文件和3个文本文件cashin.py -- 还款模块
goods_list -- 商品列表
login.py -- 主文件
menu.py -- 菜单模块
printlist.py -- 记录打印模块
record_tran.txt -- 用户操作记录
shopping.py -- 购买模块
user_list -- 用户列表
withdraw.py -- 提现模块源代码： login.py#！/usr/bin/python import sysfrom menu import menu_show while True: user = str（raw_input（"33[1;32;40mPlease input your name:33[0m"）） f = open（"user_list","r+"） for line in f.readlines（）: n = str（line.split（）[0]） p = str（line.split（）[1]） if user == n: while True: password = str（raw_input（"33[1;32;40mPlease input your password:33[0m"）） if password ！= p: print "33[1;31;40mThe password is incorrect33[0m" continue else: print "33[1;32;40myes let you in.33[0m" global money money_total = 15000 while True: print "33[1;33;40mYou total money is: 33[0m",money_total money_total = menu_show（user,money_total） else: print "33[1;31;40mThe user is not vaild, please re-input:33[0m" continue menu.py#！/usr/bin/python import sysimport osfrom shopping import show_shopping_listfrom printlist import print_listfrom withdraw import with_drawfrom cashin import cash_in def menu_show（n,mo）: print "Welcome %s, This is the ATM system:" %n print "Select what you want to do:" print " 1.
