The post mentions it will be coming in 2018

This is something that lgtm.com supports. Right now, I can't find a Python project with a dependency on a vulnerable package to show you, but here's the page that shows Django's dependencies (and this is where a known vulnerable version would be highlighted).

https://lgtm.com/projects/g/django/django/dependencies

You can try https://gemnasium.com, it has Python support.

You can use requires.io or pyup.io right now for Python.

One can use sourceclear.com for Python support.

But hey!

  Python support coming in 2018.
