Python 基于文本的随机问题测验

Question

这是一个基于文本的测验示例，其中程序应该给出 5 个问题供用户随机回答。问题是它工作得很好，但只给出了 3 个随机问题，然后就停止了。

import random

question1=["The answer is A","A","a"]
question2=["The answer is B","B","b"]
question3=["The answer is A","A","a"]
question4=["The answer is F","F","f"]
question5=["The answer is A","A","a"]

questions=[question1,question2,question3,question4,question5]

used_questions=[]

while len(used_questions)!=len(questions):

    random_question=random.choice(questions)

    while random_question in used_questions:
        random_question=random.choice(questions)

    used_questions.append(random_question)

    print([random_question[0]])

    players_answer=input("")

    if players_answer in random_question:
        print("\nCorrect!")
    else:
       print("\nWrong!")

Answer 1

问题 1、3 和 5 相同，因此您只有三个独特的问题，因此只显示三个问题。只要 used_questions 的一个元素等于 random_question，random_question in used_questions 的计算结果为 True；他们不必引用内存中完全相同的列表。

正如评论和其他答案中提到的，洗牌是一种更简单的方法。

import random

questions=[
    ["The answer is A","A","a"],
    ["The answer is B","B","b"],
    ["The answer is A","A","a"],
    ["The answer is F","F","f"],
    ["The answer is A","A","a"]
]

random.shuffle(questions)
for question in questions:
    print(question[0])
    players_answer=input("")
    if players_answer in question:
        print("\nCorrect!")
    else:
       print("\nWrong!")

结果：

The answer is F
F

Correct!
The answer is A
B

Wrong!
The answer is A
Q

Wrong!
The answer is B
B

Correct!
The answer is A
A

Correct!

Answer 2

一个更简单的方法是使用 shuffle:

random.shuffle(questions)

这会随机排列您的问题。然后你可以循环 questions.
