我正在上在線課程，并且試圖使捕獲個(gè)人筆記的課程結(jié)構(gòu)的過(guò)程自動(dòng)化，并將其保存在Markdown文件中。這是一個(gè)示例章節(jié)：以下是HTML外觀的示例：  <!-- 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>我的問(wèn)題是：構(gòu)造此數(shù)據(jù)的最佳方法是什么，以便以后在編寫文本文件時(shí)可以輕松訪問(wèn)它？它會(huì)更好，以與列的數(shù)據(jù)幀chapter，lesson，lesson_link？一個(gè)具有MultiIndex的DataFrame？嵌套字典？如果是字典，我應(yīng)該給鍵命名什么？還是我錯(cuò)過(guò)了另一種選擇？某種數(shù)據(jù)庫(kù)？
