Python两种银行系统对比
简介
两种都是静态银行系统,采用的知识都差不多,接下来大家来看看那种写的好。
静态银行系统(一)
此银行系统有11种功能,分别是开户、查询、取款、存款、转账、改密、冻结、解冻、补卡、销户以及退出,功能挺齐全的。
设置访问页面和菜单页面
import time
import time
import os
import pickle
class Admin(object):
admin = 'admin'
passwd = 'passwd'
def AdminView(self):
print("**********************************************")
print("* 欢迎登录银行系统 *")
print("**********************************************")
#菜单界面
def FunctionView(self):
print("**********************************************")
print("* (1)开户 (2)查询 *")
print("* (3)取款 (4)存款 *")
print("* (5)转账 (6)改密 *")
print("* (7)锁定 (8)解锁 *")
print("* (9)补卡 (0)销户 *")
print("* 退出(q) *")
print("**********************************************")

静态银行系统(二)
此银行系统有6种功能,分别是开户、查询、取款、存款、转账以及退出,每选择一个功能都要确保用户信息是否正确。

后记
这次的小项目学会了吗,多支持一下哦!
这两种Python写的银行系统喜欢那种呢?
如果你觉得文章写的还不错,欢迎你帮助宣传扩散一下,这将是我继续更新的动力,切忌不要白嫖,会让自己变得廉价,好的文章值得分享。
