python写一个模仿ATM存取款机系统（tkinter UI实现）

self.account = account
self.pwd = pwd

# 其实可以直接用 ‘对象.money’ 获取

self.money -= n

self.root.geometry('500x250') # 设置窗口大小
self.root.title(' ATM ') # 设置窗体标题
self.items = []
''' items 用于存储目前root窗口中
已经添加了哪些组件 ，清除当前
窗口中的控件，只需要遍历items调用自己的
destroy（）方法，即可清空窗口'''
self.modle = 0 # 自定义modle为当前模式（手残应该是model，单词拼写错误）
self.entrys = [] # 自定义当前’ 输入控件 ‘的列表，
# 获取输入时，遍历该组件，调用get（）方法即可
self.accounts = {} # 保存已注册的用户{account：password,}，只存（账户，密码）键值
self.account = '' # 为空时代表并未登录，登录后置为登录账号值
self.customers = [] # 保存已存在的用户对象们，这里存的是对象值
self.func = ['1', '2', '3', '4', '5', '6', '7'] # 用于判断功能选择输入是否合法
self.funcs = {'0': self.start, '1': self.func1, '2': self.func2, '3': self.func3, '4': self.func4, '5': self.func5,
'6': self.func6, '7': self.func7}
'''
由于python中使用字典可以代替switch语句
我们直接定义8个函数
然后根据输入框获取的值，跳转执行对应的方法即可
start（）- func7（）都是根据功能动态添加UI组件，显示到 root窗口中
