對于產品串列中的一項，我有以下代碼：
<div class="nice_product_item">
<div class="npi_name">
<h2>

<span style="color:red">Stoc limitat!</span>

</a>
</h2>
</div>
<div class="price_block_list">
<span class="old_price"> 999,00 Lei </span>
<span class="price_discount">-12%</span>
<span class="cheaper_by">mai ieftin cu 120,00 lei</span>
<span class="real_price">879,00 Lei</span>
<span class="evo-credit">evoCREDIT</span></div>
</div>
</div>一些產品獲得了 price_discount 跨度，而另一些則沒有
<span class="price_discount">-12%</span>
我使用以下代碼來抓取產品名稱：
texts = []
for a in soup.select("div.npi_name a[href]"):
if a.span:
text = a.span.next_sibling
else:
text = a.string
texts.append(text.strip())
我不知道我需要什么條件才能獲得折扣產品的名稱。
注意：它必須適用于串列
uj5u.com熱心網友回復：
處理資料的一種方法可能是選擇所有有折扣的商品：
soup.select('div.nice_product_item:has(.price_discount):has(a[href])')
迭代ResultSet，選擇您需要的資訊并以結構化方式存盤它，如字典串列，以便稍后處理它，例如DataFrame并保存到 csv、json、...
