Python mechanize doesn't work when HTTPS and P

Question

I use Python 2.7.2 and Mechanize 0.2.5.
When I access the Internet, I have to go through a proxy server. I wrote the following codes, but an URLError occurred at the last line.. Does anyone have any solution about this?

import mechanize

br = mechanize.Browser()
br.set_debug_http(True)
br.set_handle_robots(False)

br.set_proxies({
    "http"  : "192.168.20.130:8080",
    "https" : "192.168.20.130:8080",})
br.add_proxy_password("username", "password")

br.open("http://www.google.co.jp/")  # OK
br.open("https://www.google.co.jp/") # Proxy Authentication Required

I don't recommend you to use Mechanize, it's outdated. Take a look at requests it will make your life a lot easier. Using proxies with requests it's just this:

import requests

proxies = {
  "http": "10.10.1.10:3128",
  "https": "10.10.1.10:1080",
}

requests.get("http://example.org", proxies=proxies)
