How to implement the random question composing function in online answering questions requires specific code examples
With the development of the Internet, more and more education and training institutions and online Education platforms have begun to use online question answering to conduct knowledge assessments. Such online question answering activities often require candidates to face a set of questions with a certain level of difficulty from a question bank, rather than just choosing a few fixed questions to answer. Therefore, it has become particularly important to implement an online question answering system with the function of randomly composing questions.
Below we will introduce how to use programming language to implement this function and give specific code examples.
First of all, we need to prepare a question bank, which should contain questions of various difficulties and types. We can use a database to store these questions. Each question should contain information such as the title of the question, the type of question (single-choice question, multiple-choice question, fill-in-the-blank question, etc.), the difficulty of the question, etc.
Next, we need to implement a function to randomly organize volumes. The function of this function is to randomly select a certain number of questions from the question bank and then return a list of these questions. We can use the following code to implement this function:
import random
def generate_paper(num_questions):
# 从数据库中查询题库中的所有题目
questions = query_questions_from_database()
# 随机选择一定数量的题目
selected_questions = random.sample(questions, num_questions)
return selected_questionsIn the above code, the parameter num_questions of the generate_paper function represents the number of questions that need to be selected. query_questions_from_databaseThe function is used to query all questions in the question bank. You can implement this function according to the specific database type and programming language used.
When we call the generate_paper function, it will randomly select a certain number of questions and return a list of these questions.
Next, we need to implement an interface for displaying questions and receiving answer results. We can use web pages to implement this interface, and use HTML, CSS and JavaScript to implement the interactive functions of the interface. The following is a simple example:
<!DOCTYPE html>
<html>
<head>
<title>在线答题系统</title>
<style>
/* CSS样式 */
</style>
</head>
<body>
<div>
<h1 id="在线答题系统">在线答题系统</h1>
<div id="question-container"></div>
<button onclick="submitAnswer()">提交答案</button>
</div>
<script>
// JavaScript代码
// 随机获取题目
fetch('/get_questions?num=5')
.then(response => response.json())
.then(questions => {
// 将题目展示到界面上
const questionContainer = document.getElementById('question-container');
questions.forEach(question => {
const questionElement = document.createElement('div');
questionElement.innerHTML = question.title;
questionContainer.appendChild(questionElement);
});
});
// 提交答案
function submitAnswer() {
// 获取答案并发送给后台
}
</script>
</body>
</html>In the above code, we use a fetch method to get the questions from the background. In the fetch method, we sent a request to /get_questions and specified the query parameter num as 5, which means we need to get 5 questions. The background server returns the corresponding number of questions based on this parameter.
We can also implement a button to submit the answer on the interface. When the button is clicked, the answer is obtained and sent to the background for judgment.
The above is a simple sample code to implement the function of random question formation in online answering questions. You can make corresponding modifications and extensions according to actual needs to meet specific business needs.
The above is the detailed content of How to implement the random question composing function in online answering questions. For more information, please follow other related articles on the PHP Chinese website!
