How to pass proxy-authentication (requires digest auth) by using python requests module

Question

I was using Mechanize module a while ago, and now try to use Requests module.
(Python mechanize doesn't work when HTTPS and Proxy Authentication required)

I have to go through proxy-server when I access the Internet.
The proxy-server requires authentication. I wrote the following codes.

import requests
from requests.auth import HTTPProxyAuth

proxies = {"http":"192.168.20.130:8080"}
auth = HTTPProxyAuth("username", "password")

r = requests.get("http://www.google.co.jp/", proxies=proxies, auth=auth)

The above codes work well when proxy-server requires basic authentication.
Now I want to know what I have to do when proxy-server requires digest authentication.
HTTPProxyAuth seems not to be effective in digest authentication (r.status_code returns 407).

No need to implement your own! in most cases

Requests has built in support for proxies, for basic authentication:

proxies = { 'https' : 'https://user:password@proxyip:port' } 
r = requests.get('https://url', proxies=proxies) 

see more on the docs

Or in case you need digest authentication HTTPDigestAuth may help.
Or you might need try to extend it like yutaka2487 did bellow.

Note: must use ip of proxy server not its name!
