[Wikidata] Enable claims with the same property, but different value for claimit.py
completed by: Allen Guo
PyWikibot  is a Python-based framework to write bots for MediaWiki. There
are currently 2 versions of pywikibot currently used:
- version 1.0 (also known as pywikibot-compat) is the legacy version
- version 2.0 (also known as pywikibot-core) is a rewrite of the original
framework, focusing solely on MediaWiki wikis with an API (version 1.14 or
newer) and offering an improved internal architecture.
Wikidata  is the Wikimedia project that hosts interwiki links and different data snippets about the various articles in Wikipedia, Wikivoyage and Wikimedia Commons. Current support for Wikidata in Pywikibot is incomplete.
claimit.py adds claims (or facts, if you prefer) to Wikidata items based on categories. The purpose of this task is to add the capability to add claims with the same property, but different values. Note that there is already a patch for this bug , but it needs more work.
In order for this task to be considered completed, your patch needs to be reviewed and merged in the repository. Please allow at least 12h for this to happen. See also the bug report at 
After you have successfully claimed this task in Google Melange please do use the bug report  in Bugzilla for communication instead of Google Melange. This allows more PWB developers to be reached! General development questions can be asked on the Pywikibot mailing list and the #pywikipediabot IRC channel.
