python - 制作问答游戏（Python）

Question

我是 Python 编程的初学者，刚刚完成了我在 python 中的程序级编程。

我正在使用面向对象编程制作一个问答游戏。我遇到了一个我无法解决的问题。

这是我的代码：

from question_model import Question
from data import question_data

question_bank = []

for i in question_data:
    for j in range(0, 13):
        questions_ans = Question(i[j].key, i[j].value)
        question_bank.append(questions_ans)

print(question_bank)

该question_model文件是：

class Question:

def __init__(self, text, answer):
    self.text = text
    self.answer = answer

question_data名单是：

question_data = [
{"text": "A slug's blood is green.", "answer": "True"},
{"text": "The loudest animal is the African Elephant.", "answer": "False"},
{"text": "Approximately one quarter of human bones are in the feet.", "answer": "True"},
{"text": "The total surface area of a human lungs is the size of a football pitch.", "answer": "True"},
{"text": "In West Virginia, USA, if you accidentally hit an animal with your car, "
         "you are free to take it home to eat.", "answer": "True"},
{"text": "In London, UK, if you happen to die in the House of Parliament, "
         "you are entitled to a state funeral.", "answer": "False"},
{"text": "It is illegal to pee in the Ocean in Portugal.", "answer": "True"},
{"text": "You can lead a cow down stairs but not up stairs.", "answer": "False"},
{"text": "Google was originally called 'Backrub'.", "answer": "True"},
{"text": "Buzz Aldrin's mother's maiden name was 'Moon'.", "answer": "True"},
{"text": "No piece of square dry paper can be folded in half more than 7 times.", "answer": "False"},
{"text": "A few ounces of chocolate can to kill a small dog.", "answer": "True"}
]

这是我的代码图像：

如控制台中所示，该question_bank列表也是空的。它应该给出位置地址，不是吗？

而且，question_data是文件中的一个变量，data由字典列表组成。我正在尝试遍历字典列表，所以我使用了 2 个for-loops。

该代码没有显示任何错误，否则它可以给我一些关于我错在哪里的提示。我的迭代和追加方式是否正确？

你能指出上面代码中的错误吗？

Answer 1

这是您如何将 Question 类的实例添加到您的 question_bank 列表的方法：

class Question:
    def __init__(self, text, answer):
        self.text = text
        self.answer = answer

question_bank = []
question_data = [
{"text": "A slug's blood is green.", "answer": "True"},
{"text": "The loudest animal is the African Elephant.", "answer": "False"},
{"text": "Approximately one quarter of human bones are in the feet.", "answer": "True"},
{"text": "The total surface area of a human lungs is the size of a football pitch.", "answer": "True"},
{"text": "In West Virginia, USA, if you accidentally hit an animal with your car, "
         "you are free to take it home to eat.", "answer": "True"},
{"text": "In London, UK, if you happen to die in the House of Parliament, "
         "you are entitled to a state funeral.", "answer": "False"},
{"text": "It is illegal to pee in the Ocean in Portugal.", "answer": "True"},
{"text": "You can lead a cow down stairs but not up stairs.", "answer": "False"},
{"text": "Google was originally called 'Backrub'.", "answer": "True"},
{"text": "Buzz Aldrin's mother's maiden name was 'Moon'.", "answer": "True"},
{"text": "No piece of square dry paper can be folded in half more than 7 times.", "answer": "False"},
{"text": "A few ounces of chocolate can to kill a small dog.", "answer": "True"}
]

for item in question_data:
    question_bank.append(Question(item["text"], item["answer"]))

print(question_bank)

但是，如果您想从这些对象中获取问题和答案，您必须使用这些类的属性：

for item in question_bank:
    print(item.text)
    print(item.answer)
