我的方法不記得其他方法的東西

Question

我的question.info()方法不記得請求question.ask()方法中的任何內容。

我認爲這是因爲它從初始函數刷新，但是當我刪除初始函數中第一次定義變量的位置時，它會返回一個很大的錯誤。

這是我的代碼：

import time 
class question: 

    def __init__(self, question, answer): 
     self.question = question 
     self.answer = answer 
     self.time = 0 
     self.attempt = 0 
     self.correct = False 

    def ask(self): 
     start = time.clock() 
     self.attempt = input(self.question) 

     self.time = time.clock() - start 
     if self.attempt == str(self.answer): 
      self.correct = True 

    def info(self): 
     print("Question:", self.question) 
     print("Answer:", self.answer) 
     print("Attempt:", self.attempt) 
     print("Correct:", self.correct) 
     print("time taken:", self.time) 


class test: 

    def __init__(self, qList): 
     self.qList = qList 
    def doTest(self): 
     for i in range(0, len(self.qList)): 
      question(self.qList[i][0],self.qList[i][1]).ask() 
      question(self.qList[i][0],self.qList[i][1]).info() 

basicMath = [ 
    ["what is 1",1], 
    ["what is 2",2], 
    ["what is 3",3], 
    ["what is 4",4], 
    ["what is 5",5], 
    ] 

task = test(basicMath) 
task.doTest() 

Answer 1

創建獨立question實例：

for i in range(0, len(self.qList)): 
    question(self.qList[i][0],self.qList[i][1]).ask() 
    question(self.qList[i][0],self.qList[i][1]).info() 

你叫question()有兩次。創建一個代替：

for i in range(0, len(self.qList)): 
    q = question(self.qList[i][0],self.qList[i][1]) 
    q.ask() 
    q.info() 

作爲單獨的實例保持其狀態另外。

你真的應該只循環直接通過self.qList，而不是在這裏使用range()：

for question_text, answer in self.qList: 
    q = question(question_text, answer) 
    q.ask() 
    q.info()
