Question

我已经开发了一个测试，我希望这样做，以便用户可以在测试实际开始之前输入他们自己的测试答案。这是我到目前为止所拥有的。如果我使用字典而不是多次执行原始输入会更好吗？或者有一种方法我可以问问用户他们的答案而不这样做。谢谢！

ready = raw_input("Are you ready to do the test?(Please enter YES/NO) ")

while ready.lower() != "yes":
    ready = raw_input("Are you ready to do the test?(Please enter YES/NO) ")

if ready.lower() == "yes":
    print "Excelent! The test will start in any second."
if ready.lower() == "no":
    print "Okay, tell me when you're ready. "
elif ready.lower() != "yes" and "no":
    print "It okay if your're not sure. The test can start in any time you want. "

count = 0

已更新：谢谢，我让循环部分失效了。现在我只需要知道如何允许用户输入他们自己的测试答案。为了澄清，我的意思是允许用户输入他们自己的答案密钥进行测试，然后开始测试。

answers = ["b", "d", "a", "a", "c", "a", "b", "a", "c", "d", "b", "c", "d", "a", "a", "c", "c", "b", "d", "a"]

count = 0
for i in range(20):
    answer = raw_input("\nQuestion " + str(i+1) + "\nWhat is your answer?\n \nA\nB\nC\nD\n\nPlease enter A, B, C or D: ");
    if answer.lower() == answers[i]:
        print "Correct"
        count = count + 1
    else:
        print "Wrong"

Answer 1

创建循环是为了避免编码。 --kidding。

您可以创建一个答案列表，其中保留了正确的选项。然后，您可以使用for循环迭代问题。这是一个例子：

answers = ["b", "d", "a", "a", "c", "a"]

count = 0
for i in range(len(answers)):
    answer = raw_input("\nQuestion " + str(i+1) + "\nWhat is your answer?\n \nA\nB\nC\nD\n\nPlease enter A, B, C or D: ");
    if answer.lower() == answers[i]:
        print "Correct"
        count = count + 1
    else:
        print "Wrong"

Answer 2

你总是可以使用2d列表和for循环，使用Dict不会保持问题的顺序，否则你可能想要使用有序的Dict ......

在2d列表中，您可以写下问题及其答案

questions = [["\nQuestion {0}\nWhat is your answer?\n \nA\nB\nC\nD\n\nPlease enter A, B, C or D: ","b"],
             ["\nQuestion {0}\nWhat is your answer?\n \nA\nB\nC\nD\n\nPlease enter A, B, C or D: ","d"],
             ["\nQuestion {0}\nWhat is your answer?\n \nA\nB\nC\nD\n\nPlease enter A, B, C or D: ","a"],
             ["\nQuestion {0}\nWhat is your answer?\n \nA\nB\nC\nD\n\nPlease enter A, B, C or D: ","c"],
             ["\nQuestion {0}\nWhat is your answer?\n \nA\nB\nC\nD\n\nPlease enter A, B, C or D: ","d"]]

count=0

for n,i in enumerate(questions):
    quest = raw_input(i[0].format(n))
    if quest.lower() == i[1]:
        print "Correct"
        count = count + 1
    elif quest.lower() != i[1]:
        print "Wrong"

Answer 3

您应该使用类。这是一个基于你到目前为止的快速模拟，它更灵活，也可以重复使用。想想你有不同等级的不同问题，但它不是一个完整的问题，但会让你开始。

我也提出了一些意见，希望代码不言自明：

class Questions:
    def __init__(self, title='', answers=[]):
        # title can then be changed to whatever you like (A,B,C,D,E,F... etc.)
        self.title = title
        # answers will be a python list, just like you have now
        self.answers = answers
        # we use a dictionary to store question N and its correct answer
        self.questions = {}
        # no of questions answered correctly
        self.count = 0
        # a boolean flag whether the test has been completed
        self.completed = False
        # check if answers are set, then loop through the list and set the key/value pair
        if self.answers:
            for i, answer in enumerate(self.answers):
                self.questions['Question ' + str(i+1)] = answer

    def start(self):
        if not self.answers:
            print "No question and answer set yet"
            return
        # you only need a YES answer, so set a while loop to break only on YES
        while raw_input('Are you ready to do the test? (Please enter YES/NO) ').lower() != 'yes':
            pass
        # reset the count in case people break in the middle of the questions
        self.count = 0
        # just iterate the list, and get the key/value pair as a question
        for i, answer in enumerate(self.answers):
            question = 'Question ' + str(i+1)
            ans = raw_input(question +'\n' + self.title)
            if ans.lower() == self.questions[question]:
                print "Correct"
                self.count += 1
            # quite obvious, if not Correct, that's Wrong
            else:
                print "Wrong"
        # once all questions answered, set completed flag as True
        self.completed = True
        # now go to get_result to print all stats you want
        return self.get_result()

    def get_result(self):
        # to check if all questions are actually completed
        if not self.completed:
            print "You still haven't completed the test yet"
            return
        print "\n|Congratulation!,", "You have completed the test."
        print "|Here's your result."
        print "|Total score: " + str(self.count) + "/20"
        division = float(self.count)/float(20)
        multiply = float(division*100)
        result = round(multiply)
        print "|Total percentage is", int(result), "%"
        if result <= 70:
            print ("|Sorry, you have failed.\n|You should study more.")
        # well again, if result is not <=70, it will be above.
        else:
            print ("|Congratulations, you have passed!")

用法：

# set the title so do not repeat yourself on each question asked
# and the answers will be a list of the Correct answer, you get the idea
myquestions = Questions(title='What is your answer?\nPlease enter A, B, C or D: ', answers=['b','d','a','c','a','b','a','c','d','b','c','d','a','c','c','b','d','a'])

# After you instantiated your class, the __init__ is called, and so the questions dictionary is created automatically
 myquestions.questions
{'Question 1': 'b',
 'Question 10': 'b',
 'Question 11': 'c',
 'Question 12': 'd',
 'Question 13': 'a',
 'Question 14': 'c',
 'Question 15': 'c',
 'Question 16': 'b',
 'Question 17': 'd',
 'Question 18': 'a',
 'Question 2': 'd',
 'Question 3': 'a',
 'Question 4': 'c',
 'Question 5': 'a',
 'Question 6': 'b',
 'Question 7': 'a',
 'Question 8': 'c',
 'Question 9': 'd'}

要开始测试，请致电myquestions.start()

myquestions.start()
Are you ready to do the test? (Please enter YES/NO) yes

Question 1
What is your answer?

A
B
C
D
Please enter A, B, C or D: b
Correct

...

Question 18
What is your answer?

A
B
C
D
Please enter A, B, C or D: s
Wrong

|Congratulation!, You have completed the test.
|Here's your result.
|Total score: 1/20
|Total percentage is 5 %
|Sorry, you have failed.
|You should study more.

完成所有问题后，系统会调用get_result并打印您的统计信息。

我的代码并未真正优化，但这应该让您了解如何使用 Class 来解决您将来遇到的任何类似问题。
