Just a quick note that I released mwclient 0.6.2. This version incorporates a lot of fixes from the last year, as I have not had time for earlier intermediate releases. Users are recommended to upgrade to the latest version, especially if they use the library for uploading images.
Mwclient is a Python library that allows easy access to the MediaWiki API and should be more or less usable on MediaWiki 1.11 or higher and should graciously fallback when the write api is disbled.
See https://apps.sourceforge.net/mediawiki/mwclient/ for download links.
