AttributeError User Questionsオブジェクトに属性がありません

Question

このコードセクションが正しく動作しません。誰かがそれに間違っていることを理解できるかどうか疑問に思いましたか？

import os 
from tkinter import * 
import time 
import sys 

root = Tk() 
root.attributes("-fullscreen", True) 

class User_Questions: 
    def __init__(self, master): 

     self.master = master 
     master.title("MIT") 

     global frame 
     frame = Frame(master) 
     frame.pack() 

     self.choosen_questions = [] 
     self.choosen_answers = [] 

     self.choosen_questions_file = open(os.path.expanduser("~/Desktop/Bradfield/Project/" + str(test_choice) + "/Questions.txt")) 
     self.choosen_answers_file = open(os.path.expanduser("~/Desktop/Bradfield/Project/" + str(test_choice) + "/Answers.txt")) 

     for line in self.choosen_questions_file: 
      self.new_question = line.replace("\n","") 
      self.choosen_questions.append(self.new_question) 

     for line in self.choosen_answers_file: 
      self.new_answer = line.replace("\n","") 
      self.choosen_answers.append(self.new_answer) 

     self.correct_answers = 0 

     self.question_label = Label(frame, text = self.choosen_questions[0].replace("1. ",""), font = "Helvetica", fg = "blue") 
     self.question_label.pack() 

     self.answer_entry = Entry(frame, text = "", font = "Helvetica") 
     self.answer_entry.pack() 

     self.answer_entry.bind('<Return>', self.question) 

     self.check_test_exists_button = Button(frame, text="SUBMIT", font = "Helvetica", command=self.question) 
     self.check_test_exists_button.pack() 

     self.back_button = Button(frame, text="GO BACK", font = "Helvetica", command=self.go_back) 
     self.back_button.pack() 

     self.quit_button = Button(frame, text="QUIT", font = "Helvetica", command=master.destroy) 
     self.quit_button.pack() 

     def question(self, event): 
      for i in range(1, len(self.choosen_questions)): 
       return(self.choosen_questions[i+1].replace(i+". ","")) 

     def go_back(self): 
      frame.destroy() 
      my_gui = User_Choose_Test(root) 

これは出力エラーです： はAttributeError： 'User_Questions' オブジェクトがquestionとgo_backのインデントが間違っている何の属性 '質問'

を持っていませんが。インデントされていない1つのレベルにする必要があります。
