本文例項為大家分享了python實現銀行系統的具體程式碼，供大家參考，具體內容如下
1、admin.py 定義管理員資訊和主介面顯示
#!/usr/bin/env python # coding:UTF-8 """ @version: python3.x @author:曹新健 @contact: [email protected] @software: PyCharm @file: admin.py @time: 2018/9/11 10:14 """ import time class 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 = "歡迎光臨曹氏銀行" print(s1.center(60-len(s1),"*")) for i in range(4): print("".center(60,"*")) if self.__status: print("管理員被鎖定，請聯絡大神曹新健") return -1 name = input("請輸入管理員使用者名稱：") if name != self.name: print("使用者名稱輸入錯誤") return -1 if self.checkAdminPasswd() != 0: return -1 return 0 def adminAction(self): print("""************************************************************ ***************開戶(1)****************銷戶(2)*************** ***************查詢(3)****************轉賬(4)*************** ***************取款(5)****************存款(6)*************** ***************鎖定(7)****************解鎖(8)*************** ***************改密(9)****************補卡(0)*************** ************************退出 系統(q)************************ ************************************************************ """) def checkAdminPasswd(self): n = 0 while n <= 3: if n == 3: self.status = True print("輸入超過3次，管理員被鎖定，請聯絡大神曹新健") return -1 passwd = input("請輸入密碼：") if passwd != self.__passwd: print("密碼輸入錯誤，請重新輸入") n += 1 else: print("密碼驗證成功，請稍後") 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定義銀行卡資訊
#!/usr/bin/env python # coding:UTF-8 """ @version: python3.x @author:曹新健 @contact: [email protected] @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定義銀行賬戶資訊
#!/usr/bin/env python # coding:UTF-8 """ @version: python3.x @author:曹新健 @contact: [email protected] @software: PyCharm @file: user.py @time: 2018/9/11 14:54 """ class User(): def __init__(self,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("新密碼跟舊密碼一樣") else: self.__passwd = passwd class UsersException(Exception): pass
4、functions.py銀行功能邏輯實現

5、bankManage.py 主程式
