Python-如何随机化具有 A、B、C、D 的问题

Question

我的目标是拥有它，以便它可以随机化问题。

例如，测试开始，第一个问题可能是第 8 题。Question 这个词现在只是一个评论。

我希望它看起来像这样：

What does OSI stand for?

A- Open Systematic Information
B- Open Systems Interconnect
C- Organised Stairway Interweb
D- Open Safe Internet

代码如下：

#Intro

name=input("Hello, what is your name? ")
print()
print ("Hello "+ name)
print()

valid = False
while not valid:
    ready=input("Are you ready to begin the test? (Please enter YES/NO)")
    print()

    if ready.lower() =="yes":
        print ("Excellent. Welcome to the Networking Principles test. ")
        valid = True
    elif ready.lower() =="no":
        print ("Okay, tell me when your ready. ")
    else:
        print ("Please asnwer yes or no")

count=0


if ready.lower()=="yes":
    print()
    print("Please answer each answer with A,B,C or D only. The test will now begin..."
    )


#Question 1
    print()
    print('What does OSI stand for?')
    print()
    print("A- Open Systematic Information")
    print("B- Open Systems Interconnect")
    print("C- Organised Stairway Interweb")
    print("D- Open Safe Internet")
    answer = input()

    if answer.lower() =="b":
        print ("Correct, Well Done")
        count = count + 1
    else:
        print ("Wrong Answer. The asnwer was B, OSI stands for Open Systems Interconnect")


#Question 2
    print()
    print("What is the fourth Layer of the OSI Model?")
    print()
    print("A- Transport Layer")
    print("B- Teleport Layer")
    print("C- Telecommunications Layer")
    print("D- Topology Layer")
    answer = input()

    if answer.lower() =="a":
        print ("Correct, Well Done")
        count = count + 1
    else:
        print ("Wrong Answer. Layer 4 is the Transport Layer")

Answer 1

您可以将答案放在一个列表中，然后致电random.shuffle()：

import random

answers = [
    "Open Systematic Information",
    "Open Systems Interconnect",
    "Organised Stairway Interweb",
    "Open Safe Internet",
]
random.shuffle(answers)

for letter, answer in zip("ABCD", answers):
    print("{}- {}".format(letter, answer))

每次运行时，它可能会产生不同的输出，例如：

A- Organised Stairway Interweb
B- Open Systematic Information
C- Open Safe Internet
D- Open Systems Interconnect

Answer 2

您可以将所有问题保存在一个字典列表中：

questions = [{'question': 'What does OSI stand for?',
              'correct': ['Open Systems Interconnect'],
              'incorrect': ['Open Systematic Information', 
                            'Organised Stairway Interweb',
                            'Open Safe Internet']},
             {'question': "What is the fourth Layer of the OSI Model?",
              'correct': ['Transport Layer'],
              'incorrect': ['Teleport Layer', 
                            'Telecommunications Layer', 
                            'Topology Layer']}, 
             ...]

现在您可以每次给用户随机选择的给定数量的问题：

import random
import string

to_answer = random.sample(questions, number_of_questions)

然后问问题：

for q_num, question in enumerate(to_answer, 1):
    print("Question {0}: {1}".format(q_num, question['question']))

并以随机顺序呈现答案，将每个答案与answer_key中的相应键（a、b、c 等）存储起来：

    answers = question['incorrect'] + question['correct']
    random.shuffle(answers)
    answer_key = {}
    for answer, key in zip(answers, string.ascii_lowercase):
        print("{0}: {1}".format(key, answer))
        answer_key[key] = answer

接受用户的输入：

    while True:
        user_answer = input().lower()
        if user_answer not in answer_key:
            print("Not a valid answer")
        else:
            break

最后检查它们是否正确并反馈：

    correct = question['correct']
    if answer_key[user_answer] in correct:
        print("Correct!")
    else:
        s = "Incorrect; the correct answer{0}:"
        print(s.format(" was" if len(correct) == 1 else "s were"))
        for answer in correct:
            print(answer)

这支持单个问题的多个正确答案的可能性，并且尽可能少地硬编码，因此整个事情由questions配置。这减少了代码的重复，并且使以后更容易找到错误。

示例输出（number_of_questions = 1 和 questions 如上所示）：

Question 1: What does OSI stand for?
a: Open Systematic Information
b: Open Safe Internet
c: Organised Stairway Interweb
d: Open Systems Interconnect
e
Not a valid answer
b
Incorrect; the correct answer was:
Open Systems Interconnect

Answer 3

您可以像这样从文件中提取信息，

while count < 10:
wordnum = random.randint(0, len(questionsfile)-1)
print 'What is:  ', answersfile[wordnum], ''
options = [random.randint(0, len(F2c)-1),
    random.randint(0, len(answersfile)-1),random.randint(0, len(answersfile)-1)]
options[random.randint(0, 2)] = wordnum
print '1 -', answersfile[options[0]],
print '2 -', answersfile[options[1]],
print '3 -', answersfile[options[2]],
print '4 -', answersfile[options[3]]
answer = input('\nYou  choose number ?: ')
if options[answer-1] == wordnum:

Answer 4

名称QuestionX。 然后从这些QuestionX 中随机选择一个或随机播放。

例如：

import random
def Question1():
    print('Q1:What does OSI stand for?')
    answer = raw_input()
    print(answer)

def Question2():
    print("Q2:What is the fourth Layer of the OSI Model?")
    answer = raw_input()
    print(answer)

Questions = [Question1, Question2]

#Solution 1
q = random.choice(Questions)
q()

#Solution 2
for q in random.sample(Questions, len(Questions)):
    q()

#Solution 3
random.shuffle(Questions)
for q in Questions:
    q()

如果您想随机选择问题中的选项。 你可以在上面做同样的事情。

def Question1():
    print('What does OSI stand for?')
    def A(): print("A- Open Systematic Information")
    def B(): print("B- Open Systems Interconnect")
    def C(): print("C- Organised Stairway Interweb")
    def D(): print("D- Open Safe Internet")
    choices = [A, B, C, D]
    random.shuffle(choices)
    for c in choices:
        c()

Question1()

输出：

What does OSI stand for?
B- Open Systems Interconnect
D- Open Safe Internet
C- Organised Stairway Interweb
A- Open Systematic Information

正如您在输出中看到的，您似乎不应该硬编码选项的名称。您应该在洗牌后添加 A,B,C,D。
