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

There are some code pieces that are not used by Pywikibot and a quick scan with vulture creates the output below;

$ python -m vulture ./ --min-confidence 61
pywikibot/tools/__init__.py:456: unused variable 'exc_tb' (100% confidence)
pywikibot/tools/__init__.py:456: unused variable 'exc_val' (100% confidence)
scripts/imagecopy.py:396: unused variable 'commonsconflict' (100% confidence)
scripts/redirect.py:646: unreachable code after 'break' (100% confidence)

Setup Pywikibot locally and remove these unused codes. It will be also useful to recheck this report with vulture and also before making a patch, run unit tests to make sure no regressions have been introduced.

Acceptance Criteria

• Submit a patch fixing 4 cases of unused code related to this task! You are expected to provide a patch in Wikimedia Gerrit. See https://www.mediawiki.org/wiki/Gerrit/Tutorial for how to set up Git and Gerrit.
