Well you’re right about the libraries—Python really does have everything (although sometimes those libraries are not great quality, but at least they mostly work). But Julia makes it easy to use Python libraries with Pycall. And there are big things that just don’t exist yet in the Julia world, such as a web framework. I recently tried to create a web project using Genie.jl, which advertises itself as a ready-for-prime-time web framework for Julia, and I gave up after a few days. It’s just not in the same universe as something like Django, plus it’s barely documented.
