我正在为我的学校项目做一个简单的问答游戏，我在程序执行期间更新小部件时遇到了一些麻烦。这是may程序的一部分（我知道这不是真正的智能代码，但到目前为止它有效）：
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()
是否有更新小部件的功能（如果是，如何使用它）？我在努力工作，但由于缺乏编程知识，我无法找到解决方案。
答案 0 :(得分：0)
我已经完成了这一切，你需要做的就是编辑字典，因为我已经指示添加更多问题;如果您有任何疑问，请对其进行评论。它已准备就绪：
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;

##Put questions in format 'question' : 'properanswerbuttontoclick'; see above example

###^^^Put options in format questionnumber : 'a:firstoptionb:secondoptionc:thirdoptiond:fourthoption'!
###Otherwise, this will not work properly!
