推荐答案

您可以使用此答案):

PageElement.extract()从树中删除标签或字符串.它 返回提取的标签或字符串.

PageElement.extract() removes a tag or string from the tree. It returns the tag or string that was extracted.

from bs4 import BeautifulSoup, Comment

data = """<div class="foo">
cat dog sheep goat
<!--
<p>test</p>
-->
</div>"""

soup = BeautifulSoup(data)

div = soup.find('div', class_='foo')
for element in div(text=lambda text: isinstance(text, Comment)):
    element.extract()

print soup.prettify()

因此，您得到的div没有注释:

As a result you get your div without comments:

<div class="foo">
    cat dog sheep goat
</div>
