句法:

 

下面给出的例子解释了 Beautiful Soup 中注释的概念。
示例 1:在本示例中,我们将创建一条评论。

# Initialize the object with the document
soup = BeautifulSoup(doc, "html.parser")
  
# Get the whole comment inside b tag
comment = soup.b
  
# Print the comment
print(comment)


Python3
# Import Beautiful Soup
from bs4 import BeautifulSoup

doc = ""
  
# Initialize the object with the document
soup = BeautifulSoup(doc, "html.parser")
  
# Get the whole comment inside b tag
comment = soup.b.string
  
# Print the type of the comment
print(type(comment))


输出:
