我在Python中使用beautifulsoup来获取所有链接：
links = soup.select('.cover > .card-click-target')
print(links);
但它给了我一个包含一个元素和字符串值的数组。
我的HTML代码是：
<div class="cover">
<div class="cover-image-container">
<div class="cover-outer-align">
<div class="cover-inner-align">
<img alt="Kate Mobile Lite" class="cover-image" data-cover-large="" data-cover-small="" src="" aria-hidden="true">
</div>
</div>
</div>
<a class="card-click-target" href="/s/kate_new_6" aria-label=" Kate Mobile Lite ">
<span class="movies preordered-overlay-container id-preordered-overlay-container" style="display:none">
<span class="preordered-label">Предзаказ</span>
</span>
<span class="preview-overlay-container"> </span>
</a>
</div>
<div class="cover">
<div class="cover-image-container">
<div class="cover-outer-align">
<div class="cover-inner-align">
<img alt="Kate Mobile Lite" class="cover-image" data-cover-large="" data-cover-small="" src="" aria-hidden="true">
</div>
</div>
</div>
<a class="card-click-target" href="/s/kate_new_6" aria-label=" Kate Mobile Lite ">
<span class="movies preordered-overlay-container id-preordered-overlay-container" style="display:none">
<span class="preordered-label">Предзаказ</span>
</span>
<span class="preview-overlay-container">
</span>
</a>
</div>

我不完全信任BeautifulSoup中的CSS选择器，只是一个快速搜索，你会发现this answer here谈到更新BeautifulSoup解决了他遇到的问题。
我强烈建议您write a function完成这项工作
links = soup.find_all(lambda tag: tag.parent.get('class', None) == ['cover'] \
and tag.get('class', None) == ['card-click-target'])
匿名lambda函数将搜索类card-click-target的所有标记，并确保这些标记具有类cover的父级。
