Python中随机化多个选择

Question

我想做的是把问题1到问题20的顺序随机打乱，而且在随机打乱后，我还可以在问题上输入我的答案。每次我尝试使用随机化的语句时，总是出现错误或者意外的错误。现在我的代码是按顺序打印问题。我要做的就是把问题用if和elif语句一起随机化。

{py}

Answer 1

这段代码是用来处理一些数据的。它可能涉及到一些循环、条件判断或者数据存储的操作。具体来说，代码块中的内容会按照一定的逻辑来执行，帮助程序完成特定的任务。

如果你对代码的具体功能有疑问，可以尝试逐行分析，看看每一行是做什么的。这样可以更好地理解整个程序是如何运作的。

from random import sample
d = {1: 'question A', 2: 'question B', 3: 'question C', 4: 'question D',
    5: 'question E', 6: 'question F', 7: 'question G'}
for result in [d.get(x, 'unknown') for x in sample(range(1,len(d)+1),len(d))]:
print result

Answer 2

我建议你用字典来实现这个功能，格式是这样的：{问题编号: [答案, 问题], ...}：

q_and_a = {1: ['a', 'k是什么？'], 2: ['b', 'c是什么？'], ...}。

然后你可以从这个字典中提取出所有的键，放到一个列表里，并对这个列表进行随机打乱。

import random
q_and_a = {1: ['a', 'What is k?'], 2: ['b', 'What is c?'], ...}
questions = q_and_a.keys()
random.shuffle(questions)
for i in questions:
    my_msg = "\nQuestion " + str(i) + q_and_a[i][1] + "\nA\nB\C\nD"# gets the question
    answer = raw_input(my_msg)
    while answer != q_and_a[i][0]:
        print('Incorrect! Try again!')
        answer = raw_input(my_msg)
