python tkinter 该如何让一个loop里的问题一个接一个显示

Question

想用tkinter做一个从两个list里面出题的问卷

因为有12道题，都是大同小异，就想用一个loop来循环出12次。目前的问题是一下子12题同时出来了。。。有没有什么办法能让他们依次出来，一道题点了next按钮后下一道题才会出现，试了time，os.pause 都没用。。。

万分感谢！

import tkinter as tk
import random
import time
import os

Englis=['Jan','Feb','March','April','May','June','July','August','Sept','Oct','Nov','Dec']
Spalis=['Enero','Febrero','Marzo','Abril','Mayo','Junio','Julio','Agosto','Septiembre','Octubre','Noviembre','Diciembre']

def next():
    a=0

def test():
    cholis=Englis
    sollis=Spalis

    for i in range (0,12):
        num=random.randint(0,len(cholis)-1)
        
        EnglishWord=tk.StringVar()
        EnglishWord.set('Please print out the Spanish word of '+cholis[num]+': ')
        
        SpanishWord=tk.StringVar()
        SpanishWord.set(sollis[num])
        Question=tk.Label(window,textvariable=EnglishWord,font=('Arial', 25), width=15,height=3)
        Question.pack()        
        
        e2 = tk.Entry(window, show=None, font=('Arial', 14))
        e2.pack()
        
        NextQButton=tk.Button(window, text="Next", command=next)
        NextQButton.pack()   

        
        
window=tk.Tk()
window.title('My Window')
window.geometry('1920x1080')
test()
window.mainloop()

问题是用for循环会全部一次性显示在窗口中，要实现你想要的效果，把代码作如下修改：

import tkinter as tk
import random
import time
import os

Englis = ['Jan', 'Feb', 'March', 'April', 'May', 'June',
          'July', 'August', 'Sept', 'Oct', 'Nov', 'Dec']
Spalis = ['Enero', 'Febrero', 'Marzo', 'Abril', 'Mayo', 'Junio',
          'Julio', 'Agosto', 'Septiembre', 'Octubre', 'Noviembre', 'Diciembre']
window = tk.Tk()
window.title('My Window')
window.geometry('1920x1080')
cholis = Englis
sollis = Spalis
def test():
    num = random.randint(0, len(cholis)-1)

    EnglishWord = tk.StringVar()
    EnglishWord.set(
        'Please print out the Spanish word of '+cholis[num]+': ')
    SpanishWord = tk.StringVar()
    SpanishWord.set(sollis[num])
    Question = tk.Label(window, textvariable=EnglishWord,
                        font=('Arial', 14), width=40, height=3)
    Question.pack()

    e2 = tk.Label(window, text=SpanishWord.get(), font=('Arial', 14))
    e2.pack()
    
    def next():
        test()
        Question.destroy()
        e2.destroy()
        NextQButton.destroy()
        QuitButton.destroy()
    NextQButton = tk.Button(window, text="Next", command=next)
    NextQButton.pack()
    QuitButton = tk.Button(window,text='Quit',command=window.quit)
    QuitButton.pack()
    
test()
window.mainloop()
