Google Code-in

Pywikibot is a Python-based framework to write bots for MediaWiki (more information).

Thanks to work in Google Code-in, Pywikibot now has a script called download_dump.py. It downloads a Wikimedia database dump from http://dumps.wikimedia.org/, and places the dump in a predictable directory for semi-automated use by other scripts and tests.

As @zhuyifei1999 wrote in https://gerrit.wikimedia.org/r/#/c/399179/14/scripts/maintenance/download_dump.py@84 , the script should use response.iter_content instead of response.raw. Also, it should use stream=True when fetching the content.
