我正在构建一个 Python 应用程序，我一直在考虑一个问题。Python 并非在所有设备上都可用，更不用说我使用的模块了。任何想法如何将解释器和模块嵌入到 .exe 文件中？如果我没记错的话，minecraft 本身在安装过程中会导入 Java。

我正在 tkinter 上制作应用程序，我想将图片作为背景以及所有其他按钮和标签放在上面。有些东西对我不起作用，图片与其他所有内容重叠。下面是代码：

root = Tk()
root.geometry('1920x1080')
root.title('QuizOp')
root['bg'] = 'limegreen'



generalframe = Frame(master=root, bg='limegreen')

bgimage = ImageTk.PhotoImage(Image.open("stestimage.jpg"))

bglabel = Label(root, image=bgimage)

createquizbtn = Button(generalframe, bg='white', text='Создать викторину', font='Arial 17', command=createquiz)
proitiquizbtn = Button(generalframe, bg='white', text='Пройти викторину', font='Arial 17', command=proitiquiz)
sendquizbtn = Button(generalframe, bg='white', text='Отправить викторину', font='Arial 17', command=sendquiz)
deletequizbtn = Button(generalframe, bg='white', text='Удалить викторину', font='Arial 17', command=deletequiz)
settingsbtn = Button(generalframe, bg='white', text='Настройки', font='Arial 17', command=settingscmd)


bglabel.pack()


generalframe.pack()
createquizbtn.pack()
proitiquizbtn.pack()
sendquizbtn.pack()
deletequizbtn.pack()
settingsbtn.pack()


root.mainloop()

我正在用 Python 制作一个程序，并且我正在尝试制作它，以便如果输入字段中没有字符或只有空格，那么程序将拒绝数据并要求用户填写单元格。这个方法我试过了，但是很多空格都可以绕过。仅输入空格或不输入任何内容时，如何使程序拒绝输入？

如何用另一个非嵌套函数停止一个函数？我试图用return来停止这个函数，但它没有出来。vopr2var1btnfunc 函数通过按钮调用。我想用 vopr2var1btnfunc 停止 update_time1

    variant1btn.pack_forget()
    vopr1var1lbl.pack()
    vopr1var1ent.pack()
    vopr1var1btn.pack()
    global currentvariant
    currentvariant = 'Задания для 5-6 классов'
    vopr1timerlbl.pack(anchor=CENTER)
    format1 = '%H:%M:%S'
    target1 = datetime.now() + timedelta(minutes=2)
    global update_time1
    def update_time1():
        now = datetime.now()
        if now < target1:
            remains = round((target1 - now).total_seconds())
            text = time(second=remains % 60, minute=remains // 60).strftime(format1)
            vopr1timerlbl.config(text=text)

我想做一个关于奥运会的测试程序，但是我有一个问题。我正在努力做到这一点，以便在计时器结束时过渡到下一个问题。但是发生错误并且计时器几乎没有返回或没有消失。我将代码减少到有问题的部分。我已经尝试以许多不同的方式将 return 作为函数、条件语句。

尝试使用 Python Tkinter 创建一个 3 分钟倒数计时器。3 分钟后，窗口应关闭。发生错误，我不知道为什么。当窗口启动时，只有绿色背景上的蓝色条纹。

这是代码：

from tkinter import *
from datetime import datetime
from time import strptime, time
from tkinter import *
from datetime import datetime
from datetime import timedelta

root = Tk()

root.title('QuizopTimer')

root.geometry('1000x800')

root['bg'] = 'limegreen'

def update_time():
    format = '%H:%M:%S'
    s2 = (datetime.now() + timedelta(minutes=3)).strftime(format)
    now = (datetime.now()).strftime(format)
    s3 = datetime.strptime(s2, format) - datetime.strptime(now, format)
    timerlbl.config(text=s3)
    if not s3 == '00:00:00':
        now2 = (datetime.now()).strftime(format)
        s4 = datetime.strptime(s2, format) - datetime.strptime(now2, format)
        timerlbl.config(text=s4)
    else:
        root.destroy()
    timerlbl.after(1000, update_time)


timerlbl = Label(root, font=('calibri', 50, 'bold'), background='blue', foreground='white')

timerlbl.pack(anchor=CENTER)
root.mainloop()

update_time()

错误：
