自定义刷题工具-python实现

背景：

最近想要刷题，虽然目前有很多成熟的软件，网站。但是能够支持自定义的导入题库的非常少，或者是要么让你开会员，而直接百度题库的话，正确答案就摆在你一眼能看见的地方，看的时候总觉得自己也会，然后考的时候又啥都不记得了，然后最重要的一点是自定义导入，否则现如今成熟的牛客力扣啥才是最优的选择

自定义题库要素A

代码：

代码结构如下：注意python的名称好像不太重要可以随意改

questions.json

这个就不举例了，实际上是通过xlsx文件执行QuestionsJsonGenerator自动生成的。

QuestionsJsonGenerator.py
 

import json
import openpyxl
import os
import re

class QuestionsJsonGenerator:
    def __init__(self, excel_file, json_file):
        self.excel_file = excel_file
        self.json_file = json_file
        self.questions = []

    def read_excel(self):
        workbook = openpyxl.load_workbook(self.excel_file)
        sheet = workbook.active
        rows = list(sheet.iter_rows(values_only=True))
        headers = rows[0]

        for row in rows[1:]:
            question_data = {}
            for header, value in zip(headers, row):
                if header == "标签":
                    question_data['tags'] = [tag for tag in re.split(r'[，,]', value) if tag.strip()]
                elif header == "类型":
                    question_data['type'] = value
                elif header == "问题":
                    question_data['question'] = value
                elif header == "答案":
                    if question_data['type'] == "multiple":
                        question_data['answer'] = re.split(r'[，,]', value)
                    else:
                        question_data['answer'] = value
                elif header == "答案解释":
                    question_data['explanation'] = value if value else ""
                elif header == "选项":
                    # 使用不同的分隔符对选项进行分割
                    raw_options = re.split(r'[;\n：；]+', value)
                    # 去除空白项
                    options = [opt.strip() for opt in raw_options if opt.strip()]
                    question_data['options'] = {}
                    for opt in options:
                        # 允许使用 : 或 . 作为键值分隔符
                        key_value = re.split(r'[:.]', opt)
                        if len(key_value) == 2:
                            key = key_value[0].strip()
                            val = key_value[1].strip()
                            question_data['options'][key] = val
            # 只有在处理完一行所有数据后才添加到 questions 列表中
            self.questions.append(question_data)

        # Add IDs to each question
        for i, question in enumerate(self.questions):
            question['id'] = i + 1

    def write_json(self):
        if os.path.exists(self.json_file):
            with open(self.json_file, 'r', encoding='utf-8') as file:
                data = json.load(file)
        else:
            data = {'questions': []}

        data['questions'] = self.questions

        with open(self.json_file, 'w', encoding='utf-8') as file:
            json.dump(data, file, indent=2, ensure_ascii=False)

    def generate_json(self):
        self.read_excel()
        self.write_json()

# 使用示例
excel_file = '题库/牛客-java.xlsx'  # 替换为你的Excel文件路径
json_file = 'questions.json'  # 替换为你的JSON文件路径

generator = QuestionsJsonGenerator(excel_file, json_file)
generator.generate_json()

导入模板，数据准备演示

图例：

说明：

看图，自己最好设置一个模板，还有觉得我的这种切分不够你使用习惯的自己去改代码就行，下面说明在哪改吧

标签切分

if header == "标签":
    question_data['tags'] = [tag for tag in re.split(r'[，,]', value) if tag.strip()]

答案切分

elif header == "答案":
    if question_data['type'] == "multiple":
        question_data['answer'] = re.split(r'[，,]', value)
    else:
        question_data['answer'] = value

选项切分

elif header == "选项":
    # 使用不同的分隔符对选项进行分割
    raw_options = re.split(r'[;\n：；]+', value)
    # 去除空白项
    options = [opt.strip() for opt in raw_options if opt.strip()]
    question_data['options'] = {}
    for opt in options:
        # 允许使用 : 或 . 作为键值分隔符
        key_value = re.split(r'[:.]', opt)
        if len(key_value) == 2:
            key = key_value[0].strip()
            val = key_value[1].strip()
            question_data['options'][key] = val

执行QuestionsJsonGenerator.py

执行成功后检查一个json有没有问题，这里用我这里生成的截图做参考
