Question

我正在尝试基于之前提供的变量循环遍历json列表中的整数。这是我的JSON列表：

    tracks =[
   {
      'album_name':'Nevermind',
      1:'Smells like teen spirit',
      2:'In Bloom',
      3:'Come as you are',
      4:'Breed',
      5:'Lithium',
      6:'Polly',
      7:'Territorial Pissings',
      8:'Drain You',
      9:'Lounge act',
      10:'Stay away',
      11:'On a plain',
      12:'Something in the way'
   },
   {
      'album_name':'Relapse',
      1:'Hello',
      2':'3AM',

   },

]

这是我的html循环：

<div class="single_album">
    <h2>Track list</h2>
    {% for tracks in tracks if tracks.album_name == album_name %}
        <ol>
            <li>{{ tracks[x] }}</li>
        </ol>
    {% endfor %}
</div>

如果我把1代替'x'就行了，因为它打印了第一个记录，即“1：'闻起来像青少年精神'”但是我不知道如何制作一个循环，其中x将增加每次循环，因为我不确定它是否应该放在python或html文件中。

JSON结合python循环只打印整数
