Merely knowing python does not a data scientist make.

Of course, but wouldn't one be better preparing themselves for data science by working with python/django on a web app vs working with Ruby/Rails?

I think knowing python is just a small part. So yes, it would help, just not enough for it to matter (unless you know up front that you want to do these things).
