How to implement the equivalent of urllib.urlretrieve in Python 3?

I would like to download an APK file from http://www.apkmirror.com using a different user agent. The following works in Python 2:

import urllib

class ApkURLopener(urllib.FancyURLopener):
    version = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.81 Safari/537.36'

urllib._urlopener = ApkURLopener()

download_link = 'https://www.apkmirror.com/wp-content/themes/APKMirror/download.php?id=215041'
download_file = '/tmp/apkmirror_test/youtube.apk'

if __name__ == "__main__":
    urllib.urlretrieve(url=download_link, filename=download_file)

I'm struggling a bit to find the code to do the same in Python 3 without using urllib.request.urlretrieve, which might become deprecated in the future. So far I've come up with

#!/usr/bin/python3
import urllib.request

download_link = 'https://www.apkmirror.com/wp-content/themes/APKMirror/download.php?id=215041'
download_file = '/tmp/apkmirror_test/youtube.apk'

USER_AGENT = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.81 Safari/537.36'

request = urllib.request.Request(url=download_link, headers={'User-Agent': USER_AGENT})

if __name__ == "__main__":
    response = urllib.request.urlopen(url=request)

I suspect I should use the write method of the response object, but I'm not sure how, or indeed whether this is the way to do it. Any advice?

Solution

Based on Alternative of urllib.urlretrieve in Python 3.5, I completed the Python 3 script as follows:

#!/usr/bin/python3
import urllib.request
import contextlib

download_link = 'https://www.apkmirror.com/wp-content/themes/APKMirror/download.php?id=215041'
download_file = '/tmp/apkmirror_test/youtube2.apk'

USER_AGENT = 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.81 Safari/537.36'

request = urllib.request.Request(url=download_link, headers={'User-Agent': USER_AGENT})

if __name__ == "__main__":
    response = urllib.request.urlopen(url=request)

    with open(download_file, 'wb') as out_file:
        with contextlib.closing(response) as fp:
            block_size = 1024 * 8
            while True:
                block = fp.read(block_size)
                if not block:
                    break
                out_file.write(block)
