Convert Content-Type header into file extension

Question

So what I am trying to do is convert a HEADER requests content-type into a file extension. The typical content-type is like this for html pages "text/html; charset=utf-8" that is the given response from python. I have looked into using the mimetype module with no success as it doesn't look like it accommodates what I am looking for.

Rundown:

I want to convert "text/html; charset=utf-8" into this ".html"

The typical image content-type is "image/jpeg" depending on the image type, but I am not too worried about images, given that most urls specify the image in the path. This is more for websites that don't end in "blahahah.html"

I do not want to use any libraries that are not in the base python library.

You could split and strip:

r = requests.get("http://stackoverflow.com/questions/29674905/convert-content-type-header-into-file-extension")

from mimetypes import guess_extension

print(guess_extension(r.headers['content-type'].partition(';')[0].strip()))
