Question

我正在尝试自动完成无聊的事情中的Random Quiz Generator。该项目需要编写一个python程序来生成35个测验文件和35个答案文件。每个测验文件将以随机顺序包含50个多项选择题。

我还没有完成答案文件，但是我完成了大部分测验文件的编码。我的问题：在每个测验文件中，我只有一个问题“问题50”，而不是50个问题。

我认为循环有问题，但是我不知道哪里出了错...下面是我的代码。谢谢您的帮助。

import os, random

capitals = {'Alabama': 'Montgomery', 'Alaska': 'Juneau', 'Arizona': 'Phoenix', 'Arkansas': 'Little Rock', 'California': 'Sacramento', 'Colorado': 'Denver', 'Connecticut': 'Hartford', 'Delaware': 'Dover', 'Florida': 'Tallahassee', 'Georgia': 'Atlanta', 'Hawaii': 'Honolulu', 'Idaho': 'Boise', 'Illinois': 'Springfield', 'Indiana': 'Indianapolis', 'Iowa': 'Des Moines', 'Kansas': 'Topeka', 'Kentucky': 'Frankfort', 'Louisiana': 'Baton Rouge', 'Maine': 'Augusta', 'Maryland': 'Annapolis', 'Massachusetts': 'Boston', 'Michigan': 'Lansing', 'Minnesota': 'Saint Paul', 'Mississippi': 'Jackson', 'Missouri': 'Jefferson City', 'Montana': 'Helena', 'Nebraska': 'Lincoln', 'Nevada': 'Carson City', 'New Hampshire': 'Concord', 'New Jersey': 'Trenton', 'New Mexico': 'Santa Fe', 'New York': 'Albany', 'North Carolina': 'Raleigh', 'North Dakota': 'Bismarck', 'Ohio': 'Columbus', 'Oklahoma': 'Oklahoma City', 'Oregon': 'Salem', 'Pennsylvania': 'Harrisburg', 'Rhode Island': 'Providence', 'South Carolina': 'Columbia', 'South Dakota': 'Pierre', 'Tennessee': 'Nashville', 'Texas': 'Austin', 'Utah': 'Salt Lake City', 'Vermont': 'Montpelier', 'Virginia': 'Richmond', 'Washington': 'Olympia', 'West Virginia': 'Charleston', 'Wisconsin': 'Madison', 'Wyoming': 'Cheyenne'}


states = list(capitals.keys())

for quizNum in range(35):
    quizFile = open(f"Capital_Quiz{quizNum+1}.txt",'w')
    answerFile = open(f"Capital_Quiz_answer{quizNum+1}", 'w')
    
    # Write out the header for the quiz.
    quizFile.write('Name:\n\nDate:\n\nPeriod:\n\n') 
    quizFile.write((' ' * 20) + f"State Capitals Quiz (Form {quizNum+1})") 
    quizFile.write('\n\n')
    
    random.shuffle(states)
    
    for questionNum in range(50):
        correct_answer = capitals[states[questionNum]]
        wrong_answer = list(capitals.values())
        wrong_answer.remove(correct_answer)
        wrong_answer = random.sample(wrong_answer, 3)
        answer_option = wrong_answer + [correct_answer]
        random.shuffle(answer_option)
    
        quizFile.write(f"{questionNum + 1}. What is the capital of {states[questionNum]}?\n")
        for i in range(4):
            quizFile.write(f"{'ABCD'[i]}. {answer_option[i]}\n")
        quizFile.write("\n")
        quizFile.close()

Answer 1

问题出在最后一行：

quizFile.close()

每当您写一个问题时，您都将关闭文件，因此第二个问题将覆盖第一个问题，等等，这说明了为什么最后您只有第50个问题。

要解决此问题，您可以简单地减少quizfile.close()的缩进，使其与quizfile = open ...对齐。即您不会每个问题每次都关闭文件，只有在写完所有50个问题后才关闭文件

Answer 2

您要在错误的位置关闭文件。

import os, random

capitals = {'Alabama': 'Montgomery', 'Alaska': 'Juneau', 'Arizona': 'Phoenix', 'Arkansas': 'Little Rock', 'California': 'Sacramento', 'Colorado': 'Denver', 'Connecticut': 'Hartford', 'Delaware': 'Dover', 'Florida': 'Tallahassee', 'Georgia': 'Atlanta', 'Hawaii': 'Honolulu', 'Idaho': 'Boise', 'Illinois': 'Springfield', 'Indiana': 'Indianapolis', 'Iowa': 'Des Moines', 'Kansas': 'Topeka', 'Kentucky': 'Frankfort', 'Louisiana': 'Baton Rouge', 'Maine': 'Augusta', 'Maryland': 'Annapolis', 'Massachusetts': 'Boston', 'Michigan': 'Lansing', 'Minnesota': 'Saint Paul', 'Mississippi': 'Jackson', 'Missouri': 'Jefferson City', 'Montana': 'Helena', 'Nebraska': 'Lincoln', 'Nevada': 'Carson City', 'New Hampshire': 'Concord', 'New Jersey': 'Trenton', 'New Mexico': 'Santa Fe', 'New York': 'Albany', 'North Carolina': 'Raleigh', 'North Dakota': 'Bismarck', 'Ohio': 'Columbus', 'Oklahoma': 'Oklahoma City', 'Oregon': 'Salem', 'Pennsylvania': 'Harrisburg', 'Rhode Island': 'Providence', 'South Carolina': 'Columbia', 'South Dakota': 'Pierre', 'Tennessee': 'Nashville', 'Texas': 'Austin', 'Utah': 'Salt Lake City', 'Vermont': 'Montpelier', 'Virginia': 'Richmond', 'Washington': 'Olympia', 'West Virginia': 'Charleston', 'Wisconsin': 'Madison', 'Wyoming': 'Cheyenne'}


states = list(capitals.keys())

for quizNum in range(35):
    quizFile = open(f"Capital_Quiz{quizNum+1}.txt",'w')
    answerFile = open(f"Capital_Quiz_answer{quizNum+1}", 'w')

    # Write out the header for the quiz.
    quizFile.write('Name:\n\nDate:\n\nPeriod:\n\n') 
    quizFile.write((' ' * 20) + f"State Capitals Quiz (Form {quizNum+1})") 
    quizFile.write('\n\n')

    random.shuffle(states)

    for questionNum in range(50):
        correct_answer = capitals[states[questionNum]]
        wrong_answer = list(capitals.values())
        wrong_answer.remove(correct_answer)
        wrong_answer = random.sample(wrong_answer, 3)
        answer_option = wrong_answer + [correct_answer]
        random.shuffle(answer_option)

        quizFile.write(f"{questionNum + 1}. What is the capital of {states[questionNum]}?\n")
        for i in range(4):
            quizFile.write(f"{'ABCD'[i]}. {answer_option[i]}\n")
        quizFile.write("\n")
    quizFile.close() # This should be in outer for loop

您也没有将答案写到answerFile

为什么我的python循环仅返回最后一轮结果
