将列表格式化为正确的字符串

Question

您好，我有一个问题要进行测验.. 我显示我的代码 >>> 我的课是：

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

我的主要是：

from Question import Question

question_prompt = [
    "De quels couleur sont les bananes ?",
    "De quels couleur sont les pommes ?",
    "De quels couleur sont les fraises ?"
]

question1_answers_prompt = [
    "(a) Rouge\n",
    "(b) Jaune\n",
    "(c) Bleue\n\n",
]

question2_answers_prompt = [
    "(a) Rouge\n",
    "(b) Violette\n",
    "(c) Orange\n\n",
]

question3_answers_prompt = [
    "(a) Rouge\n",
    "(b) Verte\n",
    "(c) Jaune\n\n",
]
questions = [
    Question(question_prompt[0], question1_answers_prompt[:], 'b'),
    Question(question_prompt[1], question2_answers_prompt[:], 'a'),
    Question(question_prompt[2], question3_answers_prompt[:], 'a'),
]


def run_test(questions):
    score = 0
    miss = 0
    answered = []

    for question in questions:
        print(question.prompt)
        answer = input(question.answer_prompt)

        answered.append(answer)
        if answer == question.answer:
            score += 1
        
    print(f"Tu as {score} / {len(questions)}")
    print(answered)
    

run_test(questions)

我尝试了一些技术列表理解，但我可以正确格式化我的question_answers_prompt 列表 我有这样的事情：

\>\>\> ['(a) Rouge\n', '(b) Jaune\n', '(c) Bleue\n\n']

而我需要的是：

\>\>\> (a) Rouge
    (b) Jaune
    (c) Bleue

Answer 1

您不能在answers 定义中添加格式

question1_answers_prompt = ["(a) Rouge", "(b) Jaune", "(c) Bleue", ]
question2_answers_prompt = ["(a) Rouge", "(b) Violette", "(c) Orange", ]
question3_answers_prompt = ["(a) Rouge", "(b) Verte", "(c) Jaune", ]

但只有在使用的时候

• 你想要在每一行之前有一个制表符，在每一行之后有一个换行符，所以格式为f"\t{a}\n"

• 空字符串时加入以连接每个答案行

for question in questions:
    print(question.prompt)
    answer = input("".join(f"\t{a}\n" for a in question.answer_prompt))

给予

De quels couleur sont les bananes ?
        (a) Rouge
        (b) Jaune
        (c) Bleue
b

---

更多风格

添加符号以查看要回答的行

for question in questions:
    print(question.prompt)
    print("\n".join(f"\t{a}" for a in question.answer_prompt))
    answer = input(">> ")

De quels couleur sont les bananes ?
        (a) Rouge
        (b) Jaune
        (c) Bleue
>> a

Answer 2

在这种情况下，您可能想要加入列表的元素：

for question in questions:
    print(question.prompt)
    answer = input(''.join(question.answer_prompt))
    ....

输出：

De quels couleur sont les bananes ?
(a) Rouge
(b) Jaune
(c) Bleue

...

Answer 3

我只改变你的这行代码：answer = input(question.answer_prompt)，如下所示：

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

question_prompt = [
    "De quels couleur sont les bananes ?",
    "De quels couleur sont les pommes ?",
    "De quels couleur sont les fraises ?"
]

question1_answers_prompt = [
    "(a) Rouge\n",
    "(b) Jaune\n",
    "(c) Bleue\n\n",
]

question2_answers_prompt = [
    "(a) Rouge\n",
    "(b) Violette\n",
    "(c) Orange\n\n",
]

question3_answers_prompt = [
    "(a) Rouge\n",
    "(b) Verte\n",
    "(c) Jaune\n\n",
]
questions = [
    Question(question_prompt[0], question1_answers_prompt[:], 'b'),
    Question(question_prompt[1], question2_answers_prompt[:], 'a'),
    Question(question_prompt[2], question3_answers_prompt[:], 'a'),
]


def run_test(questions):
    score = 0
    miss = 0
    answered = []

    for question in questions:
        print(question.prompt)
        answer = input(''.join(a for a in question.answer_prompt))

        answered.append(answer)
        if answer == question.answer:
            score += 1
        
    print(f"Tu as {score} / {len(questions)}")
    print(answered)
    

run_test(questions)
