将网页抓取结果存储在DataFrame或字典中

Question

我正在上在线课程，并且试图使捕获个人笔记的课程结构的过程自动化，并将其保存在Markdown文件中。这是一个示例章节：以下是HTML外观的示例：  <!-- Header of the chapter -->  <div class="chapter__header">      <div class="chapter__title-wrapper">        <span class="chapter__number">          <span class="chapter-number">1</span>        </span>        <h4 class="chapter__title">          Introduction to Experimental Design        </h4>          <span class="chapter__price">            Free          </span>      </div>      <div class="dc-progress-bar dc-progress-bar--small chapter__progress">        <span class="dc-progress-bar__text">0%</span>        <div class="dc-progress-bar__bar chapter__progress-bar">          <span class="dc-progress-bar__fill" style="width: 0%;"></span>        </div>      </div>  </div>  <p class="chapter__description">    An introduction to key parts of experimental design plus some power and sample size calculations.  </p>  <!-- !Header of the chapter --><!-- Body of the chapter -->  <ul class="chapter__exercises hidden">      <li class="chapter__exercise ">        <a class="chapter__exercise-link" href="https://campus.datacamp.com/courses/experimental-design-in-r/introduction-to-experimental-design?ex=1">          <span class="chapter__exercise-icon exercise-icon ">            <img width="23" height="23" src="https://cdn.datacamp.com/main-app/assets/courses/icon_exercise_video-3b15ea50771db747f7add5f53e535066f57d9f94b4b0ebf1e4ddca0347191bb8.svg" alt="Icon exercise video" />          </span>          <h5 class="chapter__exercise-title" title='Intro to Experimental Design'>Intro to Experimental Design</h5>          <span class="chapter__exercise-xp">            50 xp          </span></a>      </li>我的问题是：构造此数据的最佳方法是什么，以便以后在编写文本文件时可以轻松访问它？它会更好，以与列的数据帧chapter，lesson，lesson_link？一个具有MultiIndex的DataFrame？嵌套字典？如果是字典，我应该给键命名什么？还是我错过了另一种选择？某种数据库？
