request - How to download a full webpage with a Python script?

Question

Currently I have a script that can only download the HTML of a given page.

Now I want to download all the files of the web page including HTML, CSS, JS and image files (same as we get with a ctrl-s of any website).

My current code is:

import urllib
url = "https://en.wikipedia.org/wiki/Python_%28programming_language%29"
urllib.urlretrieve(url, "t3.html")

I visited many questions but they are all only downloading the HTML.

The following implementation enables you to get the sub-HTML websites. It can be more developed in order to get the other files you need. I sat the depth variable for you to set the maximum sub_websites that you want to parse to.

import urllib2
from BeautifulSoup import *
from urlparse import urljoin


def crawl(pages, depth=None):
    indexed_url = [] # a list for the main and sub-HTML websites in the main website
    for i in range(depth):
        for page in pages:
            if page not in indexed_url:
                indexed_url.append(page)
                try:
                    c = urllib2.urlopen(page)
                except:
                    print "Could not open %s" % page
                    continue
                soup = BeautifulSoup(c.read())
                links = soup('a') #finding all the sub_links
                for link in links:
                    if 'href' in dict(link.attrs):
                        url = urljoin(page, link['href'])
                        if url.find("'") != -1:
                                continue
                        url = url.split('#')[0] 
                        if url[0:4] == 'http':
                                indexed_url.append(url)
        pages = indexed_url
    return indexed_url


pagelist=["https://en.wikipedia.org/wiki/Python_%28programming_language%29"]
urls = crawl(pagelist, depth=2)
print urls

Python3 version, 2019. May this saves some time to somebody:

#!/usr/bin/env python


import urllib.request as urllib2
from bs4 import *
from urllib.parse  import urljoin


def crawl(pages, depth=None):
    indexed_url = [] # a list for the main and sub-HTML websites in the main website
    for i in range(depth):
        for page in pages:
            if page not in indexed_url:
                indexed_url.append(page)
                try:
                    c = urllib2.urlopen(page)
                except:
                    print( "Could not open %s" % page)
                    continue
                soup = BeautifulSoup(c.read())
                links = soup('a') #finding all the sub_links
                for link in links:
                    if 'href' in dict(link.attrs):
                        url = urljoin(page, link['href'])
                        if url.find("'") != -1:
                                continue
                        url = url.split('#')[0] 
                        if url[0:4] == 'http':
                                indexed_url.append(url)
        pages = indexed_url
    return indexed_url


pagelist=["https://en.wikipedia.org/wiki/Python_%28programming_language%29"]
urls = crawl(pagelist, depth=1)
print( urls )
