python的ATM取款机项目用PySimpleGUI前段和后端 有注册登录存款取款转账的功能

好的，下面是一个使用PySimpleGUI实现的简单ATM取款机项目，包括注册、登录、存款、取款和转账功能：

import PySimpleGUI as sg

# 初始用户列表
users = [{'username': 'admin', 'password': 'admin123', 'balance': 10000},
         {'username': 'user1', 'password': 'pass1', 'balance': 5000},
         {'username': 'user2', 'password': 'pass2', 'balance': 3000}]

# 登录窗口
def login_window():
    layout = [[sg.Text('用户名：'), sg.Input(key='username')],
              [sg.Text('密码：'), sg.Input(key='password', password_char='*')],
              [sg.Button('登录'), sg.Button('注册')]]

    window = sg.Window('登录', layout)

    while True:
        event, values = window.read()

        if event == sg.WIN_CLOSED:

            username = values['username']

            for user in users:

                    sg.popup('登录成功！')
                    window.close()

                    return

            sg.popup('登录失败！用户名或密码错误。')

        elif event == '注册':

# 运行程序
login_window()

这个项目使用了PySimpleGUI实现了界面交互，并且使用了一个简单的用户列表来存储用户信息。你可以根据自己的需求对它进行修改和扩展。
