Below is my code, I can't make it start another question if a question is answered. 

I have a list of questions that the app asks, but it is pointless to post them all here. I just can't figure out how to keep on asking questions.

```
from tkinter import *
from random import randint
from tkinter import ttk

def correct():
    vastus = ('correct')
    messagebox.showinfo(message=vastus)   

def first():
    box = Tk()
    box.title('First question')
    box.geometry("300x300")

    silt = ttk.Label(box, text="Question")
    silt.place(x=5, y=5)

    answer = ttk.Button(box, text="Answer 1", command=correct)
    answer.place(x=10, y=30, width=150,)

    answer = ttk.Button(box, text="Answer 2",command=box.destroy)
    answer.place(x=10, y=60, width=150)

    answer = ttk.Button(box, text="Answer 3", command=box.destroy)
    answer.place(x=10, y=90, width=150)

first()

```
