Question

我有一个要排序的整数字符串列表。格式如下：

l= ['17', '23', '35', '79', .....]

我需要将每个数字字符串转换为整数，以便我可以对它们的数值进行排序。我试过以下，

l.sort(key=int)

然而，我得到了

基数为10的int（）的文字无效：＆＃39; ＆＃39;

我认为这是由于字符串之间的空白。那是对的吗？如果是这样，我该如何解决？

                        <h4 class="panel-title">
                          <a data-toggle="collapse" data-parent="#accordion" href="#collapse4" class="collapsed">Tab4</a>
                        </h4>

                      <div id="collapse4" class="panel-collapse collapse">
                        <div class="panel-body">Lorem ipsum dolor sit amet, consectetur adipisicing elit,
                        sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,

                      </div>
                    </div>
                  </div>
        
        </div>

然后你可以按原样排序。
