提问by Kim Hyesung
I modified an html file by removing some of the tags using beautifulsoup. Now I want to write the results back in a html file.
My code:
我通过使用beautifulsoup. 现在我想将结果写回到一个 html 文件中。我的代码：
from bs4 import BeautifulSoup
from bs4 import Comment
soup = BeautifulSoup(open('1.html'),"html.parser")
[x.extract() for x in soup.find_all('script')]
[x.extract() for x in soup.find_all('style')]
[x.extract() for x in soup.find_all('meta')]
[x.extract() for x in soup.find_all('noscript')]
[x.extract() for x in soup.find_all(text=lambda text:isinstance(text, Comment))]
html =soup.contents
for i in html:
print i
html = soup.prettify("utf-8")
with open("output1.html", "wb") as file:
file.write(html)

How can I get a result the same as print i(ie. so the tag and its content appear on the same line)? Thanks.
我怎样才能得到与print i（即标签及其内容出现在同一行）相同的结果？谢谢。

Just convert the soupinstance to stringand write:
只需将soup实例转换为字符串并写入：
with open("output1.html", "w") as file:
file.write(str(soup))

For Python 3, unicodewas renamed to str, but I did have to pass in the encoding argument to opening the file to avoid an UnicodeEncodeError.
对于 Python 3，unicode已重命名为str，但我确实必须传入 encoding 参数以打开文件以避免UnicodeEncodeError.
with open("output1.html", "w", encoding='utf-8') as file:
file.write(str(soup))

Use unicode to be safe:
使用 unicode 是安全的：
with open("output1.html", "w") as file:
file.write(unicode(soup))
