在用户定义的字典中有多个正确答案

Question

我在为一堂药理学课写复习测验。我根据收到的不同问题的反馈切换了风格，但遇到了问题。我希望有多个正确的答案，因为用户可能会输入略有不同的答案。我之前使用的格式应该是这样的：

   x = "What is the starting dose for oral Enalipril in HTN?"
   ques1 = enterbox(msg = x, title = version)
   if ques1.lower() in ["2.5-5", "2.5-5mg","2.5mg"]:
        add() 
        #which is a function I had described above to track points and display that the answer was correct
        ques2()
   elif ques1.lower() in ["skip"]:
        skip()
        que2()
   else:
        loss()
        que1()

"Skip“和"Loss”只是跟踪跳过和错误输入的基本功能。

现在我尝试使用的新格式是：

from easygui import enterbox

question_answer_pairs = [
    ("What Class of medication is Enalapril?", "ACE Inhibitor"),
    ("What is the starting oral dose of Enalapril for HTN?", ["2.5-5mg", "2.5-5","2.5mg"]),
    ("which type of metabolism provides the maximum amount of ATP needed for contraction?", "aerobic")
]

VERSION = 'Pharmacology Prep Exam'

class ResultStore:
    def __init__(self):
        self.num_correct = 0
        self.num_skipped = 0
        self.num_wrong = 0

    def show_results(self):
        print("Results:")
        print("  Correct:", self.num_correct)
        print("  Skipped:", self.num_skipped)
        print("  Wrong:  ", self.num_wrong)


def ask_question(q, a, rs, retry_on_fail=True):
    while True:
        resp = enterbox(msg=q, title=VERSION)
        # Force resp to be a string if nothing is entered (so .lower() doesn't throw)
        if resp is None: resp = ''
        if resp.lower() == a.lower():
            rs.num_correct += 1
            return True
        if resp.lower() == "skip":
            rs.num_skipped += 1
            return None

          # If we get here, we haven't returned (so the answer was neither correct nor
        #   "skip").  Increment num_wrong and check whether we should repeat.
        rs.num_wrong += 1
        if retry_on_fail is False:
            return False

# Create a ResultsStore object to keep track of how we did
store = ResultStore()

# Ask questions
for (q,a) in question_answer_pairs:
    ask_question(q, a, store)

# Display results (calling the .show_results() method on the ResultsStore object)
store.show_results()

(上面的代码几乎是从另一个回答不同问题的用户那里逐字摘取的，它可以工作，但我不认为它是写出来的)好的，希望复制和粘贴是正确的，但它在第一个问题上运行良好，但在第二个问题上崩溃，返回：

  File "./APPrac.py", line 7, in <module>
    ("which type of metabolism provides the maximum amount of ATP needed for contraction?", "aerobic")
TypeError: 'tuple' object is not callable

我试着去掉括号，在答案之间加上"or“，但得到了同样的错误。在这一点上，我几乎是在摸索，因为我甚至不完全确定如何寻找帮助。

我完全是自学的，所以所有Barney级别的解释对我来说都很重要。谢谢

编辑:所以把逗号放在第6行纠正了这个问题。但是我现在得到了以下错误

Traceback (most recent call last):
   File "./dict.py", line 47, in <module>
     ask_question(q, a, store)
  File "./dict.py", line 29, in ask_question
     if resp.lower() == a.lower():
AttributeError: 'list' object has no attribute 'lower'

但是，如果我删除带有多个答案的问题，它就会消失。

Answer 1

您缺少一个逗号，所以您实际上有一个类似于[(...), (a, b)(c, d)]的列表，而不是像[(...), (a, b), (c, d)]这样的列表，在这个列表中，它认为您使用参数(c, d)调用第二个对象(a, b)。

变化

question_answer_pairs = [
    ("What Class of medication is Enalapril?", "ACE Inhibitor"),
    ("What is the starting oral dose of Enalapril for HTN?", ["2.5-5mg", "2.5-5","2.5mg"])
    ("which type of metabolism provides the maximum amount of ATP needed for contraction?", "aerobic")
]

至

question_answer_pairs = [
    ("What Class of medication is Enalapril?", "ACE Inhibitor"),
    ("What is the starting oral dose of Enalapril for HTN?", ["2.5-5mg", "2.5-5","2.5mg"]),  # <-- this comma was missing
    ("which type of metabolism provides the maximum amount of ATP needed for contraction?", "aerobic")
]
