python银行系统实现源码
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/envpython #coding:UTF-8 """ @version:python3.x @author:曹新健 @contact:617349013@qq.com @software:PyCharm @file:admin.py @time:2018/9/1110:14 """ importtime classAdmin(): def__init__(self,name,passwd): self.name=name self.__passwd=passwd self.__status=False defadminView(self): foriinrange(4): print("".center(60,"*")) s1="欢迎光临曹氏银行" print(s1.center(60-len(s1),"*")) foriinrange(4): print("".center(60,"*")) ifself.__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:") ifname!=self.name: print("用户名输入错误") return-1 ifself.checkAdminPasswd()!=0: return-1 return0 defadminAction(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)************************ ************************************************************ """) defcheckAdminPasswd(self): n=0 whilen<=3: ifn==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:") ifpasswd!=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) return0 @property defpasswd(self): returnself.__passwd @passwd.setter defpasswd(self,password): self.__passwd=password @property defstatus(self): returnself.__status @status.setter defstatus(self,st): self.__status=st if__name__=="__main__": admin=Admin("cxj","1") whileTrue: admin.adminView()
2、card.py定义银行卡信息
#!/usr/bin/envpython #coding:UTF-8 """ @version:python3.x @author:曹新健 @contact:617349013@qq.com @software:PyCharm @file:card.py @time:2018/9/1115:02 """ importrandom classCard(): def__init__(self,id,balance): self.__id=id self.__balance=balance self.status=False @property defid(self): returnself.__id @id.setter defid(self,id): self.__id=id @property defbalance(self): returnself.__balance @balance.setter defbalance(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

4、functions.py银行功能逻辑实现
