我如何获得一个python测验来随机化问题?
我的任务是使用python进行测验,将问题存储在外部文件中。然而,我不知道如何让我的问题随机化,在20个可能的问题中一次只显示10个 我尝试过使用import random,但是语法我如何获得一个python测验来随机化问题?,python,python-3.x,random,Python,Python 3.x,Random,我的任务是使用python进行测验,将问题存储在外部文件中。然而,我不知道如何让我的问题随机化,在20个可能的问题中一次只显示10个 我尝试过使用import random,但是语法random.shuffle(问题)似乎无效。我不知道现在该怎么办 question.txt文件的格式如下: 类别 问题: 答复 答复 答复 答复 正确答案 解释 我的代码: #allows program to know how file should be read def open_file(file_nam

我的代码:
#allows program to know how file should be read
def open_file(file_name, mode):
"""Open a file."""
try:
the_file = open(file_name, mode)
except IOError as e:
print("Unable to open the file", file_name, "Ending program.\n", e)
input("\n\nPress the enter key to exit.")
sys.exit()
else:
return the_file
def next_line(the_file):
"""Return next line from the trivia file, formatted."""
line = the_file.readline()
line = line.replace("/", "\n")
return line
#defines block of data
def next_block(the_file):
"""Return the next block of data from the trivia file."""
category = next_line(the_file)
question = next_line(the_file)
answers = []
for i in range(4):
answers.append(next_line(the_file))
correct = next_line(the_file)
if correct:
correct = correct[0]
explanation = next_line(the_file)
time.sleep(1.5)
#beginning of quiz questions
def main():
trivia_file = open_file("trivia.txt", "r")
title = next_line(trivia_file)
welcome(title)
score = 0
# get first block
category, question, answers, correct, explanation = next_block(trivia_file)
while category:
# ask a question
print(category)
print(question)
for i in range(4):
print("\t", i + 1, "-", answers[i])
# get answer
answer = input("What's your answer?: ")
# check answer
if answer == correct:
print("\nCorrect!", end=" ")
score += 1
else:
print("\nWrong.", end=" ")
print(explanation)
print("Score:", score, "\n\n")
# get next block
category, question, answers, correct, explanation = next_block(trivia_file)
trivia_file.close()
print("That was the last question!")
print("Your final score is", score)
main()
这是与程序相关的大部分代码。我将非常感谢您的支持。您可以阅读该文件并将其内容分成八块。要生成唯一的随机问题,可以使用
random.shuffle
,然后使用列表切片创建问题组。此外,使用collections.namedtuple
来形成问题的属性以供以后使用更为简洁:
import random, collections
data = [i.strip('\n') for i in open('filename.txt')]
questions = [data[i:i+8] for i in range(0, len(data), 8)]
random.shuffle(questions)
question = collections.namedtuple('question', ['category', 'question', 'answers', 'correct', 'explanation'])
final_questions = [question(*i[:2], i[2:6], *i[6:]) for i in questions]
现在,要创建10的组
:
group_questions = [final_questions[i:i+10] for i in range(0, len(final_questions), 10)]
结果将是一个列表,其中包含namedtuple
对象:
[[question(category='Category', question='Question', answers=['Answer', 'Answer', 'Answer', 'Answer'], correct='Correct Answer', explanation='Explanation ')]]
要从每个namedtuple
中获取所需的值,可以查找以下属性:
category, question = question.category, question.question
等等。您需要在文件的一个过程中阅读所有问题及其答案,然后可能将问题(及其答案)重新排列,最后依次提问。(另见:)
