Python 中的簡單測驗，它以“answer,question”格式讀取 csv 文件。在我決定嘗試重構我的原始代碼之前，該程序正在運行。我參考了不同的來源來確定 csv、random、classes 和 loop 是否正確編碼，但代碼不能使用這個更新的重構版本運行。原始代碼player_name = input("What is your name? ")print(f"Welcome, {player_name}, to Quiz!")play_quiz = str(input("Are you ready to play?\n"))if play_quiz != "y": exit()class Question: def __init__(self, prompt, answer): self.prompt = prompt self.answer = answer# sample quiz questions go here where ["Question", "Answer choices from a-c"]question_prompts = []questions = [ Question(question_prompts[0], "b"), Question(question_prompts[1], "a"), ]def run_test(questions): score = 0 for question in questions: answer = input(question.prompt) if answer == question.answer: score += 1 print("You answered " + str(score) + "/" + str(len(questions)) + " correct.") return input("Want to play again? (y/n): ") == "y".lower()play_again = Truewhile play_again: play_again = run_test(questions)重構代碼import csvimport random player_name = input("What is your name? ")print(f"Welcome, {player_name}, to the Quiz!")play_quiz = str(input("Are you ready to play? "))if play_quiz != "y": exit()class Question: def __init__(self, prompt, answer): self.prompt = prompt self.answer = answerdef quiz(): score = 0 questions_right = 0 quiz_file = open(characters_file, "r") quiz_data = quiz_file.readlines() random.shuffle(quiz_data) question_number = 1 for question in range(65): x = quiz_data[question].strip() data = x.split(",") Question = data.prompt[1] correct_answer = data.answer[1]def run_test(quiz_data): answer = input("What is your answer? ") if answer == correct_answer: score += 1 question_right = question_number + 1 else: print("Incorrect.") print(f"Correct answer should be: {CorrectAnswer}")我不明白我做錯了什么，因為它沒有使用下面的重構代碼運行。本質上，我做錯了什么？我是否將代碼放在錯誤的位置以使其無法運行？

我認為您錯誤地使用了Question您制作的課程。你試圖做Question = data.prompt[1]這并沒有真正意義。Question 是一個類，因此您將使用它來創建對象的實例。此外，您的班級期望值prompt并answer傳遞給它。按照您現在的設置方式，您可以按照new_question = Question("What color is the sky?", "blue"). 但是，我認為在此代碼中創建類沒有多大用處，因為您沒有附加任何方法......
下面是一個測驗類思想的例子，可以幫助你掌握 OOP 編程的概念：
import random
questions = [
"What color is the sky?",
"What year is it?"
]
answers = [
"blue",
"2019"
]
class Question:
def __init__(self):
index = random.randint(0, len(questions) - 1)
self.answer = answers[index]
self.question = questions[index]
def check_valid(self, guess):
if guess == self.answer:
return True
else:
return False
if __name__ == "__main__":
name = str(input("What's your name?\n"))
print('Welcome then {} welcome to the quiz!'.format(name))
while True:
new_question = Question()
check = False
while check is not True:
print(new_question.question)
user_guess = str(input('What do you think the answer is?\n'))
check = new_question.check_valid(user_guess)
您可以看到，在該__init__(self):部分中，代碼并未真正進行任何主要計算，而只是設置了以后可以調用的內容，例如new_question.question. 但是，您可以連接方法，像類check_valid（由壓痕連接到類def），再后來就用在這些方法的實例創建類的。我的代碼中沒有很多函數（例如退出循環的能力），但希望這能幫助您更深入地理解 OOP！
