I recently published https://github.com/metabolize/rq-dashboard-on-heroku and want to add badges to show the locked version of Python and rq-dashboard, the main dependency it’s wrapping.
This is along the lines of #2259, which was for package.json-based applications, and also included some discussion of a Python application that used `requirements.txt`. It’s useful for showing the pinned version of any dependency in a Python application that uses a lockfile.
In the future, as an alternative to reading Pipfile.lock, I could see expanding this to read Pipfile. However for my purposes I prefer to show the locked dependency, since that’s the version that a user of my package would actually get if they ran it on Heroku.
