How to save "complete webpage" not just basic html using Python

I am using following code to save webpage using Python:

import urllib
import sys
from bs4 import BeautifulSoup

url = 'http://www.vodafone.de/privat/tarife/red-smartphone-tarife.html'
f = urllib.urlretrieve(url,'test.html')

Problem: This code saves html as basic html without javascripts, images etc. I want to save webpage as complete (Like we have option in browser)

Update: I am using following code now to save all the js/images/css files of webapge so that it can be saved as complete webpage but still my output html is getting saved like basic html:

import pycurl
import StringIO

c = pycurl.Curl()
c.setopt(pycurl.URL, "http://www.vodafone.de/privat/tarife/red-smartphone-tarife.html")

b = StringIO.StringIO()
c.setopt(pycurl.WRITEFUNCTION, b.write)
c.setopt(pycurl.FOLLOWLOCATION, 1)
c.setopt(pycurl.MAXREDIRS, 5)
c.perform()
html = b.getvalue()
#print html
fh = open("file.html", "w")
fh.write(html)
fh.close()

Solution

Try emulating your browser with selenium. This script will pop up the save as dialog for the webpage. You will still have to figure out how to emulate pressing enter for download to start as the file dialog is out of selenium's reach (how you do it is also OS dependent).

from selenium import webdriver
from selenium.webdriver.common.action_chains import ActionChains
from selenium.webdriver.common.keys import Keys

br = webdriver.Firefox()
br.get('http://www.google.com/')

save_me = ActionChains(br).key_down(Keys.CONTROL)\
         .key_down('s').key_up(Keys.CONTROL).key_up('s')
save_me.perform()

Also I think following @Amber suggestion of grabbing the linked resources may be a simpler, thus a better solution. Still, I think using selenium is a good starting point as br.page_source will get you the entire dom along with the dynamic content generated by javascript.
