这只是代码的一部分。它不会替换div和href的值。这是一个美丽的汤类标签

soup = BeautifulSoup(ourUrl)
dem = soup.findAll('p')
for i in range(0,len(dem)-1):
              dk = dem[i]


              if ('<div') in dk:
                   print "it here"
                   dk =dk.replace('<div','<!--')
                   dk =dk.replace('</div>','--->')
                   dem[i] = dk
for i in range(0,len(dem)-1):
              dk = dem[i]
              if ('<a href') in dk:
                   print "it here"
                   dk =dk.replace('<a href','<!--')
                   dk =dk.replace('</a>','--->')
                   dem[i] = dk

dem值类似于：

dem =[    <p class="left-text padding-left-10">
<a href="/people" class="red-text">See all people</a>
</p>
<p class="left-text padding-left-10">

<p>He rose from the slums of Brooklyn to take on the biggest Mafia dons of the 1950s and 1960s. Joey Gallo began his criminal career as a small-time loan shark and jukebox racketeer. He became a top enforcer in the Profaci crime family, but felt he never got the respect he deserved. So Gallo formed his own gang and revolted against mafia Don Joe Profaci in a long, bloody war on the streets of New York. But there was another side to Joey Gallo--the ruthless mob leader was also an artist and an avid reader. Living in Greenwich Village with his wife Jeffie, Gallo was inspired by his beatnik neighbors and their counterculture ideas. He also began hobnobbing with New York's social elite, befriending everyone from Neil Simon to Jerry Orbach. In the end though, nothing could save Joey Gallo from a dramatic end.</p>

dem值太大而无法输入，所以我给了你一个提取物。即使有

Answer 1

如果要用包含替换标记的注释替换元素，请用新的bs4.Comment()对象替换该对象：

from bs4 import Comment

for para in soup.find_all('p'):
    for div in para.find_all('div'):
        div.replace_with(Comment(unicode(div)))
    for link in para.find_all('a', href=True):
        link.replace_with(Comment(unicode(link)))

在Python中，不是使用for循环range()，而是直接循环序列;在上面的代码中，我直接遍历.find_all()结果。

BeautifulSoup元素可以打印为好像它们只是HTML文本，但实际上它们不是字符串而是Tag() objects。不要试图将它们视为字符串。

.replace没有在美丽的汤工作
