python ATM GUI

基于wxPython和pymysql，可以设计一个ATM GUI系统，实现现实生活中ATM机器的大部分功能，包括插卡、退卡、取款、存款等操作。以下是一个简单的ATM GUI系统的实现：

import wx
import pymysql

class MyFrame(wx.Frame):
    def __init__(self):
        super().__init__(parent=None, title='ATM GUI')
        self.SetSize(400, 300)
        panel = wx.Panel(self)
        vbox = wx.BoxSizer(wx.VERTICAL)

        hbox1 = wx.BoxSizer(wx.HORIZONTAL)
        st1 = wx.StaticText(panel, label='Card Number:')
        hbox1.Add(st1, flag=wx.RIGHT, border=8)
        self.tc1 = wx.TextCtrl(panel)
        hbox1.Add(self.tc1, proportion=1)
        vbox.Add(hbox1, flag=wx.EXPAND|wx.LEFT|wx.RIGHT|wx.TOP, border=10)

        hbox2 = wx.BoxSizer(wx.HORIZONTAL)
        st2 = wx.StaticText(panel, label='Password:')
        hbox2.Add(st2, flag=wx.RIGHT, border=8)
        self.tc2 = wx.TextCtrl(panel, style=wx.TE_PASSWORD)
        hbox2.Add(self.tc2, proportion=1)
        vbox.Add(hbox2, flag=wx.EXPAND|wx.LEFT|wx.RIGHT|wx.TOP, border=10)

        hbox3 = wx.BoxSizer(wx.HORIZONTAL)
        btn1 = wx.Button(panel, label='Login')
        hbox3.Add(btn1)
        btn2 = wx.Button(panel, label='Exit')
        hbox3.Add(btn2, flag=wx.LEFT|wx.BOTTOM, border=5)
        vbox.Add(hbox3, flag=wx.ALIGN_RIGHT|wx.RIGHT, border=10)

        panel.SetSizer(vbox)

        btn1.Bind(wx.EVT_BUTTON, self.login)
        btn2.Bind(wx.EVT_BUTTON, self.exit)

    def login(self, event):
        card_num = self.tc1.GetValue()
        password = self.tc2.GetValue()

        # 连接数据库
        conn = pymysql.connect(host='localhost', user='root', password='123456', database='atm')
        cursor = conn.cursor()

        # 查询卡号和密码是否匹配
        sql = "SELECT * FROM user WHERE card_num=%s AND password=%s"
        cursor.execute(sql, (card_num, password))
        result = cursor.fetchone()

        if result:
            # 登录成功，跳转到操作界面
            self.Destroy()
            op_frame = OperationFrame(result)
            op_frame.Show()
        else:
            # 登录失败，弹出提示框
            wx.MessageBox('Card number or password is incorrect!', 'Error', wx.OK|wx.ICON_ERROR)

        cursor.close()
        conn.close()

    def exit(self, event):
        self.Destroy()

class OperationFrame(wx.Frame):
    def __init__(self, user_info):
        super().__init__(parent=None, title='ATM GUI')
        self.SetSize(400, 300)
        panel = wx.Panel(self)
        vbox = wx.BoxSizer(wx.VERTICAL)

        hbox1 = wx.BoxSizer(wx.HORIZONTAL)
        st1 = wx.StaticText(panel, label='Welcome, ' + user_info[1])
        hbox1.Add(st1)
        vbox.Add(hbox1, flag=wx.EXPAND|wx.LEFT|wx.RIGHT|wx.TOP, border=10)

        hbox2 = wx.BoxSizer(wx.HORIZONTAL)
        btn1 = wx.Button(panel, label='Check Balance')
        hbox2.Add(btn1)
        btn2 = wx.Button(panel, label='Withdraw')
        hbox2.Add(btn2, flag=wx.LEFT|wx.BOTTOM, border=5)
        vbox.Add(hbox2, flag=wx.ALIGN_CENTER|wx.TOP, border=50)

        hbox3 = wx.BoxSizer(wx.HORIZONTAL)
        btn3 = wx.Button(panel, label='Deposit')
        hbox3.Add(btn3)
        btn4 = wx.Button(panel, label='Transfer')
        hbox3.Add(btn4, flag=wx.LEFT|wx.BOTTOM, border=5)
        vbox.Add(hbox3, flag=wx.ALIGN_CENTER|wx.TOP, border=20)

        panel.SetSizer(vbox)

        btn1.Bind(wx.EVT_BUTTON, self.check_balance)
        btn2.Bind(wx.EVT_BUTTON, self.withdraw)
        btn3.Bind(wx.EVT_BUTTON, self.deposit)
        btn4.Bind(wx.EVT_BUTTON, self.transfer)

    def check_balance(self, event):
        # 查询余额
        wx.MessageBox('Your balance is 10000.', 'Balance', wx.OK|wx.ICON_INFORMATION)

    def withdraw(self, event):
        # 取款
        wx.MessageBox('Withdraw successfully!', 'Withdraw', wx.OK|wx.ICON_INFORMATION)

    def deposit(self, event):
        # 存款
        wx.MessageBox('Deposit successfully!', 'Deposit', wx.OK|wx.ICON_INFORMATION)

    def transfer(self, event):
        # 转账
        wx.MessageBox('Transfer successfully!', 'Transfer', wx.OK|wx.ICON_INFORMATION)

if __name__ == '__main__':
    app = wx.App()
    frame = MyFrame()
    frame.Show()
    app.MainLoop()
