selector = parsel.Selector(text=response)
# print(selector.get())
# exit()
#用屬性把連結撈出來
link = selector.css('.wp-block-columns.is-layout-flex.wp-container-2').getall()
print(link)
'''

這個P標籤沒有class屬性
為什麼會被提取出來
<p><a href="https://thepornlinks.com/" title="ThePornLinks.com" target="_blank" data-wpel-link="external" rel="external noopener noreferrer">ThePornLinks.com</a></p>

最佳解答

Dears,

因為你的程式語法link = selector.css('.wp-block-columns.is-layout-flex.wp-container-2').getall() 是查找符合這個CSS條件底下的所有資料，然後<p>標籤的階層在<div>標籤底下，所以才會得到這個結果。

以下幫你把階層關係整理一下。
CODE：

<div class="wp-block-columns is-layout-flex wp-container-2">
    <div class="wp-block-column is-layout-flow" style="flex-basis:100%">
        <p>
            <a href="https://thepornlinks.com/" title="ThePornLinks.com" target="_blank" data-wpel-link="external" rel="external noopener noreferrer">ThePornLinks.com</a>
        </p>
    <meta content="160728" name="xubstercom">
    </div>
</div>
