どのように間違った質問を印刷するには？

Question

私はPythonでクイズを作っています。クイズの最後に間違った質問を表示する方法を知りたいのですが。例えば、私は10の質問クイズを持っていて、3つが間違っているので、私はそれらの質問をプログラムに表示し、それらを取るためのオプションを私に与えたい。私は1つの場所ですべての質問を聞いて確認するだろう

は、ここに私のコードです。次に、不足している質問を記録するなどの変更を行うときは、変更を1か所で行うことができます。

私の例よりも、すべての質問を配列に入れ、その配列をループしてユーザーに質問することができます。

import os 

correct=0 
incorrect=0 
missed_questions=[] 

def tryagain(): 
    while True: 
     answer = input('Do you want to continue?: Press Y for yes and N for no ') 
     if answer.lower().startswith("y"): 
      print() 
     elif answer.lower().startswith("n"): 
      exit() 

def ask_question(question, correct_answer): 
    os.system('cls') # I'm not on Windows so this doesn't work for me 
    print question 
    print '' 
    answer = int(input()) 
    if answer == correct_answer: 
     print '' 
     print '' 
     global correct 
     correct += 1 
    else: 
     global incorrect 
     incorrect += 1 
     global missed_questions 
     missed_questions.append(question)

## You could go further and put the data (all of the questions, correct answers, and 
## a flag to indicate whether the user got it correct) into one array and loop 
## through the array. In that same loop you can address how to make sure 
## that the tryagain() works properly.
