See the documentation on how to append a tag:
请参阅有关如何附加标签的文档：
soup = BeautifulSoup("<b></b>")
original_tag = soup.b
new_tag = soup.new_tag("a", href="http://www.example.com")
original_tag.append(new_tag)
original_tag
# <b><a href="http://www.example.com"></a></b>
new_tag.string = "Link text."
original_tag
# <b><a href="http://www.example.com">Link text.</a></b>

Other answers are straight off from the documentation. Here is the shortcut:
其他答案直接来自文档。这是快捷方式：
from bs4 import BeautifulSoup
temp_soup = BeautifulSoup('<div id="file_history"></div>')
# BeautifulSoup automatically add <html> and <body> tags
# There is only one 'div' tag, so it's the only member in the 'contents' list
div_tag = temp_soup.html.body.contents[0]
# Or more simply
div_tag = temp_soup.html.body.div
your_new_soup.body.insert(3, div_tag)
