在测验程序中使用二维列表时出现 Python 元组错误答案

【问题标题】：Python tuple error when working with 2d lists in a quiz program在测验程序中使用二维列表时出现 Python 元组错误
【发布时间】：2019-01-19 18:09:12
【问题描述】：

我一直在开发一个简单的测验程序，其中包含一个 2d 列表来存储问题和答案，并且在我的代码中遇到了错误“builtins.TypeError：列表索引必须是整数或切片，而不是元组”。

这是我的代码：

import random 

score = 0
incorrect_answers = 0 

Questions_List = [["ANAGRAM 1: 'Agnamar'. Please enter your answer: ", 
"anagram"], ["ANAGRAM 2: 'Coterump'. Please enter your answer: ", 
"computer"], ["ANAGRAM 3: Certcor. Please enter your answer: ", "correct"], 
["ANAGRAM 4: Bleat. Please enter your answer: ", "table"]] 

random.shuffle(Questions_List) 

def answer (Questions_List, score):
    answer = input(Questions_List[score, 0]).lower()
    return answer

while score > 10:
    answer = input(Questions_List, score)

if answer == Questions_List[score, 1]:
    print ("Correct!")
    score = score + 1
elif answer != Questions_List[score, 1]:
    print ("Incorrect!")
    incorrect_answers = incorrect_answers + 1

if answer == Questions_List[score, 1]:

线路出现此错误，是什么问题？

【问题讨论】：

只写Questions_List[score][1]。

【解决方案1】：

import random 

score = 0
incorrect_answers = 0 

Questions_List = [["ANAGRAM 1: 'Agnamar'. Please enter your answer: ", 
"anagram"], ["ANAGRAM 2: 'Coterump'. Please enter your answer: ", 
"computer"], ["ANAGRAM 3: Certcor. Please enter your answer: ", "correct"], 
["ANAGRAM 4: Bleat. Please enter your answer: ", "table"]] 

random.shuffle(Questions_List) 

def answer (Questions_List, score):
    answer = input(Questions_List[score][0]).lower()
    return answer

while score > 10:
    answer = input(Questions_List, score)

if answer == Questions_List[score][1]:
    print ("Correct!")
    score = score + 1
elif answer != Questions_List[score][1]:
    print ("Incorrect!")
    incorrect_answers = incorrect_answers + 1

应该纠正你的问题

实现它的更好方法是：

import random 

score = 0
incorrect_answers = 0 

Questions_List = [["ANAGRAM 1: 'Agnamar'. Please enter your answer: ", 
"anagram"], ["ANAGRAM 2: 'Coterump'. Please enter your answer: ", 
"computer"], ["ANAGRAM 3: Certcor. Please enter your answer: ", "correct"], 
["ANAGRAM 4: Bleat. Please enter your answer: ", "table"]] 

random.shuffle(Questions_List) 
#print(Questions_List)

for i in range(0,len(Questions_List)):
  answer = input(Questions_List[i][0])
  if answer == Questions_List[i][1]:
    print("Correct!")
    score += 1
  else:
    incorrect_answers += 1
    print("Let's try again")
    continue

print("Your final score is: ",score)

更好的方法：

import random 

score = 0
incorrect_answers = 0 

Questions_List = [["ANAGRAM 1: 'Agnamar'. Please enter your answer: ", 
"anagram"], ["ANAGRAM 2: 'Coterump'. Please enter your answer: ", 
"computer"], ["ANAGRAM 3: Certcor. Please enter your answer: ", "correct"], 
["ANAGRAM 4: Bleat. Please enter your answer: ", "table"]] 

random.shuffle(Questions_List) 

def answer (Questions_List, score):
    answer = input(Questions_List[score][0]).lower()
    return answer

while (score-incorrect_answers)<len(Questions_List):
   a = answer(Questions_List, score)
   if a == Questions_List[score][1]:
       print ("Correct!")
       score+=1
   elif a != Questions_List[score][1]:
       print ("Incorrect!")
       incorrect_answers+=1
