我有一个问题与我的python，我已经复制和粘贴每件事从树莓派到PC和下载的Visual Studio代码运行它，并下载python和guizero到我的PC通过命令终端，但即使这样，当我运行我的代码，它打开了一个窗口，它约1秒没有加载，然后立即关闭后，有人能帮助，我的代码在这里：

from guizero import App, Combo, Text, CheckBox, ButtonGroup, PushButton, info
def do_booking():
    info('Booking', 'Thank you for Booking')
    print( film_choice.value )
    print( vip_seat.value )
    print( row_choice.value )
app = App(title="My second GUI app", width=500, height=200, layout="grid")
film_discription = Text(app, text='Which film do you want to watch?', grid=[0,0], align='left')
film_choice = Combo(app, options=['Star Wars', 'Harry Potter', 'Frozen', 'Lion King'], grid=[1,0], align='left')
vip_seat_discription = Text(app, text='VIP is more comfy and can go down', grid=[0,1], align='left')
vip_seat = CheckBox(app, text='VIP seat?', grid=[1,1], align='left')
row_choice_disciption = Text(app, text='Where do you want to sit?', grid=[0,2], align='left')
row_choice = ButtonGroup(app, options=[ ['Front', 'F'], ['Middle', 'M'], ['Back', 'B'] ], selected='M', horizontal=True, grid=[1,2], align='left')
book_seats = PushButton(app, command=do_booking, text='Book Seat', grid=[1,3], align='left')
app.display

我试过导入一个等待命令并使用它来阻止它关闭，但它只是说没有响应，然后当等待结束时，它关闭
