Как обновить виджет?

Question

Я делаю простую игру викторины для своего школьного проекта, и у меня возникают проблемы с обновлением виджетов во время выполнения программы. Это часть программы может быть (я знаю, что это не очень умный код, но до сих пор он работает):

EuQuestionFrame=Frame(root) 
EuQuestionFrame.pack() 

question=['question1', 'question2'] 

     a=['20 273', 'aa']   #Possible answers: first question-first column and second question-second column 
     b=['19 732', 'bb'] 
     c=['21 327', 'cc'] 
     d=['20 372', 'dd'] 
number=0 

class Questions: 
     def question(self): 
      q=Label(frame, text=question[number], font=('Arial Black', '14')).pack()   #Here program writes questions that I listed before. 

     def answers(self): 
      def correct(): 
       number=+1 

      #Here I want to update all widgets to question 2, in that way I will change number value. 

      def incorrect(): 
       print('incorrect') 

      x=[correct, incorrect] #Correct answers for first and second questions - one column for each question. Compare with possible answers I listed before. 
      y=[incorrect, correct] 
      z=[incorrect, incorrect] 
      v=[incorrect, incorrect] 

      a1= Button(EuQuestionFrame, text=a[number], width=10, activebackground='orange', 
         cursor="circle", command=x[number]) 
      a1.pack() 
      a2= Button(EuQuestionFrame, text=b[number], width=10, activebackground='orange', 
         cursor="circle", command=y[number]) 
      a2.pack() 
      a3= Button(EuQuestionFrame, text=c[number], width=10, activebackground='orange', 
         cursor="circle", command=z[number]) 
      a3.pack() 
      a4= Button(EuQuestionFrame, text=d[number], width=10, activebackground='orange', 
         cursor="circle", command=v[number]) 
      a4.pack() 

Есть ли функция (и если да, то как использовать), которые обновление виджеты? Я много работал над этим, но из-за отсутствия знаний о программировании я не смог найти решение.

Я сделал это, чтобы все, что вам нужно сделать, это редактировать словари, поскольку я дал указание добавить больше вопросов; если у вас есть какие-либо вопросы, прокомментируйте это. Он готов к запуску:

from Tkinter import * #Tkinter; If you are using 3.x, change to tkinter, emphasis on all lowercase 
from ttk import Frame, Style #You need this for the frame and style; 
import random 
class Questions(Frame): 

    def __init__(self, parent):
