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

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!
