用python写一个ATM取款机项目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Python和PySimpleGUI实现的ATM取款机项目，包含了注册、登录、存款、取款和转账等功能。代码如下：

import PySimpleGUI as sg

# 定义窗口布局
layout_login = [
    [sg.Text('欢迎使用ATM取款机')],
    [sg.Text('请输入账号'), sg.Input(key='-ACCOUNT-')],
    [sg.Text('请输入密码'), sg.Input(key='-PASSWORD-', password_char='*')],
    [sg.Button('登录'), sg.Button('注册')],
]

layout_main = [
    [sg.Text('请选择操作')],
    [sg.Button('查询余额'), sg.Button('取款')],
    [sg.Button('存款'), sg.Button('转账')],
    [sg.Button('退出')]
]

layout_register = [
    [sg.Text('欢迎注册')],
    [sg.Text('请输入账号'), sg.Input(key='-ACCOUNT-')],
    [sg.Text('请输入密码'), sg.Input(key='-PASSWORD-', password_char='*')],
    [sg.Button('确认注册')],
]

layout_deposit = [
    [sg.Text('请输入存款金额')],
    [sg.Input(key='-DEPOSIT-')],
    [sg.Button('确认存款')],
]

layout_withdraw = [
    [sg.Text('请输入取款金额')],
    [sg.Input(key='-WITHDRAW-')],
    [sg.Button('确认取款')],
]

layout_transfer = [
    [sg.Text('请输入转账账号'), sg.Input(key='-TO-')],
    [sg.Text('请输入转账金额'), sg.Input(key='-AMOUNT-')],
    [sg.Button('确认转账')],
]

# 创建窗口
window_login = sg.Window('ATM取款机', layout_login)
window_main = None
window_register = None

window_withdraw = None
window_transfer = None

# 用户信息
user_info = {
    '1001': {
        'password': '123456',
        'balance': 1000,
    },
    '1002': {
        'password': '123456',
        'balance': 2000,
    }
}

# 当前登录用户

        if account in user_info and password == user_info[account]['password']:
            current_user = account
            window_login.hide()
            window_main = sg.Window('ATM取款机', layout_main)
            break
        else:
            sg.popup('账号或密码错误')

                'balance': 0,
            }
            sg.popup('注册成功')
            window_register.close()
            window_login.un_hide()

        break

        amount = int(values['-WITHDRAW-'])
        if amount <= user_info[current_user]['balance']:
            user_info[current_user]['balance'] -= amount
            sg.popup(f'取款成功，当前余额为{user_info[current_user]["balance"]}')
            window_withdraw.close()
            window_main.un_hide()
        else:
            sg.popup('余额不足')

# 进入转账界面
while window_transfer is not None:
    event, values = window_transfer.read()
    if event == sg.WIN_CLOSED:

            else:
                sg.popup('余额不足')
        else:
            sg.popup('该账号不存在')

这个ATM取款机项目使用了多个PySimpleGUI窗口，每个窗口对应一个功能，通过隐藏和显示窗口来实现不同功能之间的切换。在后端方面，该项目使用了一个字典来存储用户信息和账户余额，通过读写字典来实现各种操作。需要注意的是，这个项目只是一个简单示例，实际应用中还需要加入更多的安全性和容错处理。
