本文实例为大家分享了python实现银行系统的具体代码，供大家参考，具体内容如下

1、admin.py 定义管理员信息和主界面显示

#!/usr/bin/env python# coding:UTF-8 """@version: python3.x@author:曹新健@contact: 617349013@qq.com@software: PyCharm@file: admin.py@time: 2018/9/11 10:14""" import timeclass Admin(): def __init__(self,name,passwd): self.name = name self.__passwd = passwd self.__status = False def adminView(self): for i in range(4): print("".center(60,"*")) s1 = "欢迎光临曹氏银行" print(s1.center(60-len(s1),"*")) for i in range(4): print("".center(60,"*")) if self.__status: print("管理员被锁定，请联系大神曹新健") return -1 name = input("请输入管理员用户名：") if name != self.name: print("用户名输入错误") return -1 if self.checkAdminPasswd() != 0: return -1 return 0 def adminAction(self): print("""***************************************************************************开户(1)****************销户(2)******************************查询(3)****************转账(4)******************************取款(5)****************存款(6)******************************锁定(7)****************解锁(8)******************************改密(9)****************补卡(0)***************************************退出 系统(q)************************************************************************************ """) def checkAdminPasswd(self): n = 0 while n <= 3: if n == 3: self.status = True print("输入超过3次，管理员被锁定，请联系大神曹新健") return -1 passwd = input("请输入密码：") if passwd != self.__passwd: print("密码输入错误，请重新输入") n += 1 else: print("密码验证成功，请稍后") time.sleep(2) return 0 @property def passwd(self): return self.__passwd @passwd.setter def passwd(self,password): self.__passwd = password @property def status(self): return self.__status @status.setter def status(self, st): self.__status = st if __name__ == "__main__": admin = Admin("cxj","1") while True: admin.adminView()

2、card.py定义银行卡信息

#!/usr/bin/env python# coding:UTF-8 """@version: python3.x@author:曹新健@contact: 617349013@qq.com@software: PyCharm@file: card.py@time: 2018/9/11 15:02""" import random class Card(): def __init__(self,id,balance): self.__id = id self.__balance = balance self.status = False @property def id(self): return self.__id @id.setter def id(self,id): self.__id = id @property def balance(self): return self.__balance @balance.setter def balance(self,balance): self.__balance = balance if __name__ == "__main__": card = Card(1000) print(card.id) print(card.balance)

3、user.py定义银行账户信息

#!/usr/bin/env python# coding:UTF-8 """@version: python3.x@author:曹新健@contact: 617349013@qq.com@software: PyCharm@file: user.py@time: 2018/9/11 14:54""" class User(): def __init__(self,name,idCard,phone,passwd,card): self.__name = name self.__idCard = idCard self.phone = phone self.__passwd = passwd self.card = card @property def name(self): return self.__name @name.setter def name(self,name): self.__name = name @property def idCard(self): return self.__idCard @idCard.setter def idCard(self, idCard): self.__idCard = idCard @property def passwd(self): return self.__passwd @passwd.setter def passwd(self, passwd): if self.__passwd == passwd: raise UsersException("新密码跟旧密码一样") else: self.__passwd = passwd class UsersException(Exception): pass

4、functions.py银行功能逻辑实现

#!/usr/bin/env python# coding:UTF-8 """@version: python3.x@author:曹新健@contact: 617349013@qq.com@software: PyCharm@file: functions.py@time: 2018/9/11 11:01""" import pickle,os,randomfrom admin import Adminfrom card import Cardfrom user import User,UsersException pathAdmin = os.path.join(os.getcwd(), "admin.txt")pathUser = os.path.join(os.getcwd(), "users.txt") def rpickle(path): if not os.path.exists(path): with open(path,"w") as temp: pass with open(path,'rb') as f: try: info = pickle.load(f) except EOFError as e: info = "" return info def wpickle(objname,path): if not os.path.exists(path): with open(path,"w") as temp: pass with open(path,'wb') as f: pickle.dump(objname,f) def adminInit(): # print(pathAdmin) adminInfo = rpickle(pathAdmin) if adminInfo: admin = adminInfo # print(admin.status) else: admin = Admin("cxj", "1") return admin def adminClose(admin): wpickle(admin, pathAdmin) def randomId(users): while True: str1 = "" for i in range(6): ch = str((random.randrange(0, 10))) str1 += ch if not users.get(str1,""): return str1 def openAccount(users): name = input("请输入您的姓名：") idCard = input("请输入您的身份证号：") phone = input("请输入您的电话号码：") passwd = input("请输入账号密码：") balance = int(input("请输入您的金额：")) id = randomId(users) card = Card(id,balance) user = User(name,idCard,phone,passwd,card) users[id] = user print("请牢记您的银行卡号%s" %(id)) def userInit(): userInfo = rpickle(pathUser) if userInfo: users = userInfo else: users = {} return users def userClose(users): wpickle(users, pathUser) def getUser(users): id = input("请输入您的银行卡号：") if not users.get(id, ""): print("您输入的卡号不存在") user = None else: user = users.get(id) return user def transferUser(users): id = input("请输入转账（对方）的银行卡号：") if not users.get(id, ""): print("您输入的卡号不存在") user = None else: user = users.get(id) return user def changeMoney(user,res): money = int(input("请输入交易金额：")) if money <= 0: print("输入金额有误") return 0 if res: if money > user.card.balance: print("余额不足") return 0 return money def serchAccount(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 res = checkUserPasswd(user) if not res: print("您的账户名称为%s,您的余额为%s" % (user.name, user.card.balance)) def transferAccount(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 res = checkUserPasswd(user) if not res: transUser = transferUser(users) if not transUser: return -1 money = changeMoney(user,1) if not money: return -1 user.card.balance -= money transUser.card.balance += money print("交易成功") def withdrawal(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 res = checkUserPasswd(user) if not res: money = changeMoney(user,1) if not money: return -1 user.card.balance -= money print("交易成功") def deposit(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 res = checkUserPasswd(user) if not res: money = changeMoney(user,0) if not money: return -1 user.card.balance += money print("交易成功") def delAccount(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 res = checkUserPasswd(user) if not res: users.pop(user.card.id) print("账户删除成功") return 0 def lockAccount(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 checkUserPasswdLock(user) def unlockAccount(users): user = getUser(users) if not user: return -1 if not user.card.status: print("账户不需要解锁") return -1 res = checkUserPasswd(user) if not res: user.card.status = False print("账户解锁成功！") def changePasswd(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 res = checkUserPasswd(user) if not res: newPasswd = input("请输入新密码：") try: user.passwd = newPasswd except UsersException as e: print(e) else: print("密码修改成功！") def makeNewCard(users): user = getUser(users) if not user: return -1 if user.card.status: print("账户被锁定，请解锁后再使用其他功能") return -1 res = checkUserPasswd(user) if not res: id = randomId(users) userinfo = users[user.card.id] users.pop(user.card.id) users[id] = userinfo users[id].card.id = id print("补卡成功，请牢记您的银行卡号%s" % (id)) def checkUserPasswd(user): n = 0 while n <= 3: if n == 3: user.card.status = True print("输入超过3次，账户被锁定，请解锁后再使用其他功能") return -1 passwd = input("请输入您的账户密码：") if passwd != user.passwd: print("密码输入错误，请重新输入") n += 1 else: return 0 def checkUserPasswdLock(user): n = 0 while n <= 3: if n == 3: print("输入超过3次，账户锁定失败！") return -1 passwd = input("请输入您的账户密码：") if passwd != user.passwd: print("密码输入错误，请重新输入") n += 1 else: user.card.status = True print("账户锁定成功！") return 0

5、bankManage.py 主程序
