给我一段代码，它能网页保存内容为mht文件

以下是使用Python的 requests 和 beautifulsoup4 模块实现将网页保存为mht文件的代码：

import requests
from bs4 import BeautifulSoup

url = "https://www.example.com"  # 将此处的网址替换为你要保存的网页URL
response = requests.get(url)

soup = BeautifulSoup(response.content, "html.parser")
html = soup.prettify()

mhtml_content = f"""Content-Type: multipart/related; boundary=boundary-example-1

--boundary-example-1
Content-Type: text/html; charset=UTF-8
Content-Transfer-Encoding: quoted-printable

{html}

--boundary-example-1--"""

headers = {
    "Content-Type": "application/x-mimearchive",
    "Content-Disposition": "attachment; filename=index.mht",
}

with open("index.mht", "w", encoding="utf-8") as f:
    f.write(mhtml_content)

print("mht文件保存成功！")

将代码中的 `url` 替换为你要保存的网页的URL，运行代码即可将网页保存为名为 `index.mht` 的文件。
