Question

我已经开始编写多项选择测验，但是我希望Python程序能够随机选择一个用户尚未回答的看不见的问题，这个问题不应该包含以前错误解答的问题。我目前的代码如下：

example.py

print ('WELCOME TO THE MULTIPLE CHOICE TEST\n')
name = input('WHAT IS YOUR NAME? ')
print ('\nHI THERE ' + name + '! LET''S PLAY A GAME!\n')
print ('I will ask you 10 questions and give you three choices for each 
question.\n\nYou select which choice is the correct answer. Eg. A, B or 
C\n')
print ('\n-----------------------------------------------------------\n')

score = 0
score = int(score)  #Convert the 0 into a number so we can add scores

print ('Q1: What is 1 + 1\n')
print ('A. 1')
print ('B. 2')
print ('C. 0')
print ('')

Q1answer = "B"
Q1response= input('Your answer : ').upper()

if (Q1response != Q1answer):
    print ('Sorry, that is incorrect!')
else:
    print ('Well done! ' + Q1response + ' is correct!')
    score = score + 1

print ('Your current score is ' + str(score) + ' out of 10')
print ('\n-----------------------------------------------------------\n')

print ('Q2: What is 0 + 0')
print ('A. 0')
print ('B. 1')
print ('C. -1')
print ('')

Q2answer = "A" or "a"
Q2response= input('Your answer : ').upper()

if (Q2response != Q2answer):
    print ('Sorry, that is incorrect!')
else:
    print ('Well done! ' + Q2response + ' is correct!')
    score = score + 1

print ('Your current score is ' + str(score) + ' out of 10') 
print ('\n-----------------------------------------------------------\n')

-------------------------------------------- --------------------------------

修订后的代码：

import random
score = 0
score = int(score)

questions = {  # (also contains the answers)
"What is 1 + 1?": "2",
"What is 0 + 0?": "0",
"What is 1 + 2?": "3",
"What is 1 + 3?": "4",
"What is 1 + 4?": "5",
"What is 2 + 1?": "3",
"What is 3 + 2?": "5",
"What is 8 + 2?": "10",
"What is 6 + 0?": "6",
"What is 6 + 1?": "7",
"What is 7 + 1?": "8",
"What is 10 + 0?": "0",
}
learned_questions = set()

while len(questions) > len(learned_questions):
    unanswered_questions = set(questions) - learned_questions
    chosen_question = random.choice(list(unanswered_questions))
    correct_answer = questions[chosen_question]

    print (chosen_question)
    given_answer = input()

    if given_answer == correct_answer:
        print ("Correct!")
        learned_questions.add(chosen_question)
        score = score + 1
        print ('Your current score is ' + str(score) + ' out of 10')
        print ('\n-----------------------------------------------------------\n')
    else:
        print ("Wrong!  Correct answer would have been:", correct_answer)
        print ('Your current score is ' + str(score) + ' out of 10')
        print ('\n-----------------------------------------------------------\n')

Answer 1

收集所有现有问题：

questions = {  # (also contains the answers)
    "What is 1 + 1?": "2",
    "What is 0 + 0?": "0",
}

制作所有正确回答的问题的另一个集合：

learned_questions = set()

通过从两组的差异中做出选择，只选择不属于learned_questions的问题：

unanswered_questions = set(questions) - learned_questions
chosen_question = random.choice(list(unanswered_questions))
correct_answer = questions[chosen_question]

询问用户的答案：

print chosen_question
given_answer = raw_input()

检查给定答案是否正确，将此问题添加到学习问题的集合中：

if given_answer == correct_answer:
  print "Correct!"
  learned_questions.add(chosen_question)
else:
  print "Wrong!  Correct answer would have been:", correct_answer

在所有问题都得到解决之前，将所有这些完成：

while len(questions) > len(learned_questions):
    …

现在一起：

questions = {  # (also contains the answers)
    "What is 1 + 1?": "2",
    "What is 0 + 0?": "0",
}
learned_questions = set()
while len(questions) > len(learned_questions):
  unanswered_questions = set(questions) - learned_questions
  chosen_question = random.choice(list(unanswered_questions))
  correct_answer = questions[chosen_question]
  print chosen_question
  given_answer = raw_input()
  if given_answer == correct_answer:
    print "Correct!"
    learned_questions.add(chosen_question)
  else:
    print "Wrong!  Correct answer would have been:", correct_answer

如何让我的测验随机选择用Python看不见的问题？
